Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to engine oil purging systems and more particularly pertains to a new engine oil purging system for accelerating air entering a valve cover to force oil in an engine into an oil pan of the engine when the oil is being changed.

2. Description of the Prior Art

The use of engine oil purging systems is known in the prior art. While these devices fulfill their respective, particular objectives and requirements, the need remains for a system that has certain improved features that include a mounting collar that is quickly coupled to a valve cover to seal around an oil fill hole. Additionally, the system should include a plurality of blades to accelerate the air passing through the system and entering the valve cover.

SUMMARY OF THE INVENTION

The present invention meets the needs presented above by generally comprising a housing that has a bore extending through a top end and a bottom end of the housing. A mounting collar is mounted to the housing. The mounting collar is positioned adjacent the bottom end of the housing and extends through an oil fill hole to be secure the housing to a valve cover. An axle is positioned in the bore of the housing and is aligned with a longitudinal axis of the housing. A plurality of main blades is coupled to the axle. The main blades are rotated when the axle is rotated to accelerate the air being drawn from the top end of the housing and exhausted from the bottom end to blow oil out of engine valves and into an oil pan of an engine. A drive mount is removably mounted to the top end of the housing. The drive mount has at least one vent aperture extending therethrough that is in fluid communication with the bore. A drive spindle extends through and is rotatably mounted to the drive mount. The drive spindle has a drill end extending upwardly from the drive mount and a drive end engaging the axle when the drive mount is mounted to the top end of the housing. The drill end is removably engageable with an electric drill and is rotatable by the electric drill to rotate the axle along with the main blades to draw air into the vent aperture and push the air outwardly of the bottom end of the housing.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new engine oil purging system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 8, the air accelerating system 10 generally comprises a housing 12 that has a bore 18 therein that extends through a top end 14 and a bottom end 16 of the housing 12. The housing 12 may include a majority portion adjoining the top end 14 which is frusto-conical in shape and which tapers outwardly from the top end 14 toward the bottom end 16 and a minority portion adjoining the bottom end 16 and tapering inwardly from the majority portion to the bottom end 16. This causes air driven into the top end to increase in pressure at it transfers from the majority portion to the minority portion.

A mounting collar 20 is mounted to the housing 12. The mounting collar 20 is positioned adjacent the bottom end 16 of the housing 12 and extends through an oil fill hole 22. The mounting collar 20 is securable to a valve cover 24 of an engine to secure the housing 12 to the valve cover 24. The mounting collar 20 is comprised of a compressible material to form a seal against the valve cover 24 to inhibit air leaking out between the mounting collar 20 and the valve cover 24. The mounting collar 20 includes a body section 26 and a threaded shoulder 28 downwardly extending from the body section 26. The shoulder 28 threadably engages the valve cover 24 adjacent to the oil fill hole 22 to secure the body section 26 and the housing 12 to the valve cover 24. A combined height of the housing 12 and the mounting collar 20 is between 10 cm and 20 cm.

An axle 30 is positioned in the bore 18 of the housing 12. The axle 30 is aligned with a longitudinal axis of the housing 12. A plurality of main blades 32 is coupled to the axle 30 and the main blades 32 are vertically elongated along the axle 30. Each of the main blades 32 is rotated when the axle 30 is rotated to act as an impeller to accelerate the air is drawn from the top end 14 of the housing 12 and exhausted from the bottom end 16 to blow oil out of engine valves and into an oil pan of the engine. The air is accelerated as the air passes by the main blades 32.

The system 10 may comprise a kit which includes a pair of provided heads 40. Each of the heads 40 is removably couplable to the top end 14 of the housing 12 and more particularly may be threadably coupled to the top end 14. Each of the heads 40 enables air to be driven into the bore 18 and outwardly of the bottom end 16. Only one of the heads 40 is usable at a time.

The pair of heads 40 includes a drive mount 42 that is removably mounted to the top end 14 of the housing 12. The drive mount 42 has vent apertures 44 extending therethrough that are in fluid communication with the bore 18. A drive spindle 46 extends through and is rotatably mounted to the drive mount 42. The drive spindle 46 has a drill end 48 extending upwardly from the drive mount 42 and a drive end 50 engaging the axle 30 when the drive mount 42 is mounted to the top end 14 of the housing 12. The drill end 48 is removably engageable with a conventional electric drill. The drive spindle 46 is rotatable by the electric drill to rotate the axle 30 along with the main blades 32 to draw air into the vent apertures 44 and push the air outwardly of the bottom end 16 of the housing 12. The drill end 48 may either be coupled to the drill chuck or it may be formed to receive a bit attached to the drill.

The other of the pair of heads 40 includes an air funnel 52 that is removably mountable to the top end 14 of the housing 12. The air funnel 52 includes a receiver 54 extending upwardly from the air funnel 52. The receiver 54 is in fluid communication with the bore 18 when the air funnel 52 is mounted on the housing 12. The receiver 54 is fluidly engageable with a compressed air line to allow compressed air to direct through the receiver 54 and into the bore 18 to push air outwardly of the bottom end 16 of the housing 12. A valve 56 is mounted on the air funnel 52 and is in communication with the receiver 54 to selectively open or close an air conduit 58 fluidly connecting the receiver 54 and the bore 18. The air funnel 52 provides a tight fit between the compressed air line and the oil fill hole 22.

A plurality of fan blades 60 is coupled to and radiate outwardly from the axle 30. The fan blades 60 are positioned adjacent to the bottom end 16 of the housing 12 and are rotated when the axle 30 is rotated. The fan blades 60 accelerate the air that has passed through the housing 12 into the valve cover 24 to force the air into the valve cover 24.

In use, the shoulder 28 of the mounting collar 20 is inserted into the oil fill hole 22 of the valve cover 24 to secure the mounting collar 20 and the housing 12 to the valve cover 24. The drive mount 42 is coupled to the top end 14 of the housing 12 so that that the drive spindle 46 engages the axle 30. A drill is then engaged with the drive spindle 46 to rotate the axle 30 and pull air into the bore 18 and exhaust it out of the bottom end 16 of the housing 12 to force the oil in the valves to the oil pan to be drained. If a compressed air supply is available, it may be used with the air funnel 52 to direct air through the housing 12 and into the oil fill hole 22.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
