Abstract
A coupling member for use in priming a fluid pump of an internal combustion engine, the coupling member including a first end, a second end, and a cylindrical length therebetween. The first end of the coupling member may be configured to axially engage a drive shaft of a rotational drive, a plurality of fins may extend along at least a portion of the cylindrical length, and the plurality of fins may be configured to engage an oil drive gear of an internal combustion engine. Each fin from the plurality of fins may protrude radially from an outer surface of the coupling member, and the coupling member may be further configured to translate a rotational force provided by the rotational drive to the oil drive gear of the internal combustion engine.
Claims17
A coupling member comprising:
- a first end;
- a second end;
- and
- a cylindrical length therebetween,
- wherein the first end of the coupling member is configured to axially engage a drive of a rotational drive, a plurality of fins extend along only a portion of the cylindrical length, the plurality of fins configured to engage an oil drive gear of an internal combustion engine, each fin from the plurality of fins protruding radially from an outer surface of the coupling member to translate a rotational force provided by the rotational drive to the oil drive gear of the internal combustion engine.
A pump priming device for an internal combustion engine with a fluid pump having at least one of a suction side and a pressure side, the pump priming device comprising:
- a coupling member comprising:
- a first end,
- a second end,
- a cylindrical length therebetween, and
- a plurality of fins extending along only a portion of the cylindrical length,
- wherein each fin from the plurality of fins protrudes radially from an outer surface of the coupling member;
- a rotational drive;
- and
- a drive shaft mounted to the rotational drive,
- wherein the coupling member, via the fins, and the drive shaft translates the rotational force provided by the rotational drive to an oil drive gear of the internal combustion engine, such that at least one of the suction side and pressure side of the fluid pump are primed.
A method for priming a fluid pump of an internal combustion engine having at least one of a suction side and a pressure side, the method comprising:
- providing a coupling member, wherein the coupling member comprises:
- a first end,
- a second end,
- a cylindrical length therebetween, and
- a plurality of fins extending along only a portion of the cylindrical length, wherein each fin from the plurality of fins protrudes radially from an outer surface of the coupling member;
- inserting a fluid into the fluid pump of the internal combustion engine;
- engaging the coupling member, via the fins, and a drive shaft of a rotational drive such that a rotational force provided by the rotational drive is translated to the coupling member;
- aligning each fin from the plurality of fins with a corresponding geometrical portion of an oil drive gear of the internal combustion engine;
- inserting each fin from the plurality of fins into the corresponding geometrical portion of the oil drive gear such that each fin from the plurality of fins is capable of translating the rotational force applied to the coupling member to the oil drive gear;
- generating the rotational force using the rotational drive and translating the rotational force through the coupling member and into the oil drive gear of the internal combustion engine;
- and
- forcing the fluid inserted into the fluid pump into at least one of the suction side and the pressure side of the fluid pump.
