Referring in particular to the Figures submitted as a part hereof, magnetically operated pumping apparatus 100 is provided in a reciprocating embodiment illustrated herein in FIGS. 1 through FIG. 7 and a rotational embodiment wherein the elements thereof are illustrated herein in FIG. 8 through FIG. 20. While not illustrated herein, it should be understood within the scope of the present invention that the magnetically operated pumping apparatus 100 is configured to be electrically coupled to a conventional AC or DC power supply in order to provide the necessary electrical current to provide operation of the pumping member 20 as described herein.

Referring now to FIG. 1 through FIG. 7, the reciprocating embodiment of the magnetically operated pumping apparatus 100 is illustrated herein. The magnetically operated pumping apparatus 100 includes a cylinder housing 5 having an interior volume 6 that is hollow. It should be understood within the scope of the present invention that the cylinder housing 5 can be manufactured from durable materials such as but not limited to plastic. Furthermore, it should be understood within the scope of the present invention that the cylinder housing 5 could be provided in a plurality of alternate lengths and diameters as needed for the application in which the magnetically operated pumping apparatus 100 will be employed. Circumferentially disposed around the cylinder housing 5 is a coil 10. The coil 10 is a conventional coil of copper wire that is electrically coupled to a suitable power source. The coil 10 is configured to have electrical current transmit therethrough wherein the current direction and timing controls the movement of the pumping member 20 as a result of the impact thereof on the rare earth magnet 18. The electrical current and direction thereof in the coil 10 creates an electromagnetic field which interacts with the rare earth magnet 18 disposed within the pumping member 20 to provide the desired movement of the pumping member 20 as is further discussed herein. In the reciprocating embodiment of the magnetically operated pumping apparatus 100 the coil 10 is divided into four separately controlled portions wherein each portion is independently operated by separate circuits controlling the charging and discharging of each portion of the coil 10 in order to control the electromagnetic field produced by the coil 10 and provide the reciprocating movement of the pumping member 20 as the rare earth magnet 18 interacts with the changes in electromagnetic field of the coil 10.

The magnetically operated pumping apparatus 100 includes intake assembly 25 wherein the intake assembly 25 is integrally formed with the cylinder housing 5. The intake assembly 25 functions as a one-way valve so as to permit fluid to flow into and around the pumping member 20. The intake valve assembly 25 includes a seal 26 and seal retaining shaft 27 wherein the seal 26 and seal retaining shaft 27 function to allow fluid to enter the interior volume 6 of the cylinder housing 5 as the pumping member 20 moves from its first position to its second position. It should be understood within the scope of the present invention that the intake assembly 25 could be configured with alternate elements in order to facilitate introduction of fluid into the interior volume 6 of the cylinder housing 5. The pumping member 20 has operably coupled to the second end 22 thereof a flange member 30. The flange member 30 is manufactured from rubber or similar flexible material and is configured to move between a first position and a second position depending upon the travel direction of the pumping member 20. The flange member 30 during travel between the second position of the pumping member 20 to the first position, as is illustrated herein in FIG. 5, will bend so as to allow fluid to pass through the channels 19 and into the interior volume 6 rearwards of the pumping member 20. During movement from the second position to the first position, the fluid passing through the channels 19 applies pressure to the flange member 30 providing bending thereof as illustrated herein in FIG. 5. This provides filling of the interior volume 6 of the cylinder housing 5. The movement of the pumping member 20 is controlled by the manipulation of the electrical current through the portions of the coil 10. As illustrated herein in FIGS. 6 and 7, the flange member 30 is in a position so as to be planar in orientation and adjacent second end 22 of the pumping member 20 during the movement of the pumping member 20 from its first position to its second position. In the second position of the flange member 30 as illustrated herein in FIGS. 6 and 7, the pumping member 20 is traversing towards the second end 2 of the cylinder housing 5. As the pumping member 20 traverses towards second end 2, fluid disposed within the interior volume 6 between the second end 22 of the pumping member 20 and the second end 2 of the cylinder 5 is propelled outwards from the cylinder housing 5 at the second end 2 thereof. Conversely, as the pumping member travels towards first end 1 of the cylinder housing 5 the flange member 30 bends to an arcuate shape, as is illustrated herein in FIG. 5, so as to allow fluid to pass through the channels 19 past the second end 22 in order to fill the interior volume 6 between the second end 22 of the pumping member 20 and the second end 2 of the cylinder housing 5 with fluid. This reciprocating motion of the pumping member 20 provides continuous filling and evacuation of the interior volume 6 of the cylinder housing 5 and can be employed in various alternate applications. While an embodiment of the flange member 30 has been illustrated and discussed herein, it is contemplated within the scope of the present invention that the flange member 30 could be provided in various alternate embodiments in order to achieve the desired functionality as described herein.

Now referring to FIG. 8 through FIG. 20, the rotational embodiment of the magnetically operated pumping apparatus 100 is illustrated therein. The rotational embodiment includes cylinder housing 40 wherein cylinder housing 40 has a hollow interior volume 43 and further includes a first end 41 and second end 42. The cylinder housing 40 is manufactured from a durable material such as but not limited to plastic. The cylinder housing 40 has surroundably present thereto a housing 50. The housing is configured to surround and protect the magnetically operated pumping apparatus 100 and it should be understood within the scope of the present invention that the housing 50 could be provided in alternate shapes and sizes. The cylinder housing 40 has surroundably mounted thereto a stator coil 60 proximate the midpoint thereof. The stator coil 60 includes frame 61 and copper wire 62. The stator coil 60 is electrically coupled to a conventional power supply operable to produce a current through the copper wire 62. The stator coil 60 produces an electromagnetic field that interacts with the magnets 70 disposed within the pumping member 80. The electrical current transmitted through the stator coil 60 provides an electromagnetic field resulting in an interaction with the magnets 70 that result in a rotational movement of the pumping member 80.

The cylinder housing 40 has circumferentially mounted thereto a first magnet bearing 45 and a second magnet bearing 48. The first magnet bearing 45 and second magnet bearing 48 are axially poled magnets that function to maintain the pumping member 80 in place during rotation thereof. While the preferred shape of the first magnet bearing 45 and second magnet bearing 48 is ring shaped, it is contemplated within the scope of the present invention that the first magnet bearing 45 and second magnet bearing 48 could be provided in alternate shapes and positioned circumferentially about the cylinder housing 40. The magnets 70 disposed within the pumping member 80 are diametrically poled so as to interact with the stator coil 60 to produce a rotational movement of the pumping member 80. It should be understood within the scope of the present invention that the pumping member 80 could have alternate quantities of magnets disposed in the interior volume thereof. The pumping member 80 has formed on the outer surface thereof a plurality of channels 81 wherein the channels 81 extend the length of the pumping member 80. The channels 81 are helical in form and are operable to promote fluid flow therethrough during rotation of the pumping member 80. The pumping member 80 includes a first end 85 and a second end 88 that are both tapered in shape. The tapered form of the first end 85 and the second end 88 provides the ability for fluid to flow therepast during rotational movement of the pumping member 88. As electrical current is transmitted through the stator coil 60, the resulting electromagnetic field interacts with the magnets 70 to produce rotation of the pumping member 80. It should be understood within the scope of the present invention that the directional current transmitted through the stator coil 60 could be altered in order to provide the desired rotational direction of the pumping member 80. It should be understood within the scope of the present invention that the rotational embodiment of the magnetically operated pumping apparatus 100 could be provided in alternate sizes in order to fulfill the needs of a desired application.

While specifically illustrated herein, it should be understood within the scope of the present invention that the magnetically operated pumping apparatus 100 could include cooling components to provide temperature control thereof as needed for various applications. By way of example but not limitation, the magnetically operated pumping apparatus 100 could employ fans, heat sinks and other similar elements to provide cooling of the magnetically operated pumping apparatus 100.

In the preceding detailed description, reference has been made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments, and certain variants thereof, have been described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that other suitable embodiments may be utilized and that logical changes may be made without departing from the spirit or scope of the invention.
