DESCRIPTION

The electricity generators and methods for generating electricity will be described with reference to FIGS. 1A-5D. Referring first to FIG. 1A, an example prime mover 10 in accordance with the present disclosure is depicted. In accordance with at least one cross section, prime mover 10 is depicted in FIG. 1B and in accordance with another cross section, prime mover 10 is depicted in FIG. 1C and includes housing and generator components.

Referring to FIGS. 1A-1C, prime mover 10 can include a cylindrical member 12. This cylindrical member need not be and is not perfectly cylindrical. Member 12 need only be balanced upon center rod 13 as if it were cylindrical. Therefore, portions of member 12 may be counterbalanced with opposing portions, portions may be void, but what is included in member 12 are bases 16A and/or 16B which can be considered opposing bases about the outer sidewalls 15 of member 12. In accordance with example implementations, member 12 can be considered a rotor.

Additional members 14 are also provided. Members 14 are depicted in pairs; however, it is contemplated that a single member 14 may be sufficient to facilitate operation of prime mover 10. Further, members 14 can be cylindrical in the same sense that member 12 is cylindrical, however, wherein member 14 is fixed in relation to rotating member 12, member 14 can be of any shape having sidewalls 17 and base 18.

Prime mover 10 includes opposing bases 18A and 16A and/or 18B and 16B. In accordance with example implementations, member 12 or 14 can rotate about center rod 13 or with center rod 13, in relation to the other member. Therefore, member 12 may rotate in relation to a fixed member or members 14. Likewise, member or members 14 may rotate in relation to fixed member 12.

Referring to FIG. 1C, at least one cross section of prime mover 10 configured as a generator is shown with housing 20 about member 12. Housing 20 can include a generator component 24 with a complimentary generator component 22 fixed to member 20. These generator components can be considered electrically conductive and or magnetic components and can be operably fixed to the housing and the rotating member, whether that be member 12 or member 14.

Prime mover 10 will have a plurality of chambers associated with the opposing bases. These chambers will facilitate the conversion of source energy to mechanical energy that drives the rotating member in relation to the fixed member.

Referring next to FIG. 2, an example electrical generator 30 is shown. Generator 30 can include a housing 20 which has a substantially cylindrical internal space 32 defined by an annular wall 34 extending between opposing end walls 36 and 38. Undulating cam surfaces 40 and 42 can define chambers of bases 18A and 18B. There is also a substantially cylindrical rotor 12 disposed within housing 20 between the undulating cam surfaces 40 and 42. Rotor 12 is rotatably mounted on a center rod 13 which can be considered a drive shaft. In this depicted configuration, rotor 13 defines a plurality of slots extending axially therethrough, for example slots 44 and 46, each of which receives a corresponding slidable vane, for example vanes 48 and 50. These vanes can be slidably engaged to reciprocate axially in a direction parallel to the center rod 13 when the rotor 12 rotates. Electrical generator 30 can also include a plurality of operable ports to facilitate the introduction of source energy into the chambers between the opposing bases and the exhaust of spent source energy, for example air intake port 38, a fuel injection port 40, and an exhaust port 42 on each end wall thereof. The air intake port 52, the fuel injection port 54, and the exhaust port 56 are depicted for a generator configured as a combustion prime mover.

Referring next to FIG. 3, an isometric view of a rotor of generator 30 is shown. In accordance with example configurations, rotor 12 can include electrically conductive components such as armature windings 86 and 88. In this configuration, magnets, for example, magnets 82 and 84 (See FIG. 2), can be disposed within the housing 20. As depicted generator 30 is configured as a permanent magnet generator which also include additional operable elements such as a commutator and brush which are not shown. In other examples, the generator may include field windings in place of magnets and accordingly be an induction generator. In all configurations, a rotating member includes a generator component that rotates in relation to a fixed member that includes a complimentary generator component. Typically, this is the rotor rotating in relation to the housing.

The components of the prime mover of the present disclosure can facilitate the conversion of source energy to mechanical energy in multiple ways, for example combustion or expansion may be utilized to rotate the rotor about the rod 13.

Referring to FIGS. 4A-4D, combustion is utilized. Air received through the air intake port 52 during an intake stroke is trapped between adjacent vanes 48 and 50 as shown in FIG. 4A. The air is then compressed during a compression stroke due to a decreasing volume between the adjacent vanes 48 and 50 as the vanes move towards the rotor 12 as shown in FIG. 4B. Fuel received though the fuel injection port 54 is ignited and expands during an expansion stroke due to an increasing volume between the adjacent vanes 48 and 50 as the vanes move away from the rotor 12 as shown in FIG. 4C. Exhaust gases are then forced out through the exhaust port 56 during an exhaust stroke as shown in FIG. 4D.

Referring next to FIGS. 5A-D, an expansion driven prime mover is utilized. A working high-pressure fluid is received through intake port 60 and is trapped between vanes 48 and 50 as shown in FIG. 5A. The high-pressure fluid expands during the expansion stroke due to the increasing volume between vanes 48 and 50 as shown in FIG. 5B. The high-pressure fluid continues to drive the vanes until the leading vane 50, reaches the exhaust port 61 as shown in FIG. 5C, at which time the expanded gasses are exhausted and the cycle repeats as shown in FIG. 5D.

As disclosed, a prime mover is provided that can include a housing defining an annular wall extending between opposed end walls. Spaced-apart and opposed undulating cam surfaces are disposed within the housing. A rotor is also disposed within the housing between the undulating cam surfaces. The rotor can be configured to slidably receive a plurality of vanes. The rotary engine further includes an integrated generator having an armature winding mounted on the rotor and a magnet mounted within the internal chamber on the annular wall of the housing.

In compliance with the statute, embodiments of the disclosure have been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the entire disclosure is not limited to the specific features and/or embodiments shown and/or described, since the disclosed embodiments comprise forms of putting the disclosure into effect. The disclosure is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted in accordance with the doctrine of equivalents.
