摘要： A pump, comprising a pump insert which is arranged in an accommodating space of a cup-shaped pump housing. The pump insert comprises a first housing part and a second housing part between which a rotor is rotatably arranged, and a stroke ring which surrounds the rotor and is arranged between the first housing part and the second housing part. A spring flexing along the rotational axis is arranged between the accommodating housing and the second housing part. The spring comprises a spring structure which is made of metal and which imbues the spring with its essential spring characteristics along the rotational axis. The spring is supported towards the second housing part in a region which is arranged in axial alignment with the stroke ring in the direction of the rotational axis, and thus presses the second housing part against the stroke ring.

摘要： A rotary engine casing having at least one end wall of an internal cavity for a rotor including a seal-engaging plate sealingly engaging the peripheral wall to partially seal the internal cavity and a member mounted adjacent the seal-engaging plate outside of the internal cavity. The member and seal-engaging plate having abutting mating surfaces which cooperate to define between them at least one fluid cavity communicating with a source of liquid coolant. When the casing includes a plurality of rotor housings, the end wall may be between rotor housings. A method of manufacturing a rotary engine casing is also discussed.

摘要： A fluid pump includes a housing, a rotary shaft, and pump units which are contained in the housing and sucks in, pressurizes, and discharges fluid with being rotationally driven by the rotary shaft. The housing has a suction passage conducting the fluid from a suction port to the pump unit, a discharge passage conducting the fluid from the pump unit to a discharge port, a return passage returning a portion of the fluid flowing through the discharge passage to an upstream side of the pump unit, and a control valve controlling a flow of the returned fluid. The return passage is formed so as to conduct the returned fluid in the same direction as a flow of a sucked fluid flowing through the suction passage to make the returned fluid flow together with the sucked fluid.

摘要： In accordance with one embodiment, the gear pump comprises a first gear meshed with a second gear as well as a housing, in which the gears are supported. The housing includes a first void, which at least partly adjoins a first side surface of the first gear, and a second void, which at least partly adjoins a second side surface of the first gear. The gear pump further comprises a fluid intake channel configured to direct fluid towards the gears, wherein at least one deflector is arranged within the fluid intake such that an incident fluid flow is diverted towards the first void as well as to the second void.

摘要： A gear pump includes a drive gear mounted to a first gear shaft, a driven gear meshable with the drive gear, a plurality of journal bearings, and a first porting path. The first porting path is adapted to provide high pressure fluid communication from a discharge of the gear pump to a first hybrid pad location for a first journal bearing selected from the plurality of journal bearings, the first hybrid pad location circumferentially adjacent to a first fluid film location. Each location is disposed annularly between an inner surface of the first journal bearing, and an outer surface of the first gear shaft or second gear shaft corresponding to the first journal bearing.

摘要： A guided-vane rotary internal combustion engine including a plurality of working chambers which are separated from one another by way of vane assemblies which rotate with a rotor assembly about an axis employs a rotor assembly having a plurality of sectors wherein each sector is associated with a corresponding working chamber and a plurality of spark plugs wherein each spark plug is mounted within a corresponding sector for igniting an air/fuel mixture contained within a corresponding working chamber. A rotor disk is mounted upon the rotor assembly for rotation therewith and acts as a distributor through which energizing charges are conducted to the spark plugs. In addition, a controller is utilized for selectively activating or de-activating the working chambers of the engine upon the occurrence of a predetermined event.
