摘要:
The automotive electrical oil pump (10) comprises an oil displacement pumping unit (14) comprising a pump rotor (96) rotating in a pump chamber (100) for pumping pressurized oil to an oil recipient. Further, the oil pump comprises an electric driving motor (12) for driving the pump rotor (96) of the pumping unit (14), an electrical connector plug (26) for electrically connecting the driving motor (12) to a power source, and a fluid connector (22) comprising a pump inlet (77) and a pump outlet (44) which are fluidically connected to a corresponding chamber inlet (104) and chamber outlet (108). The fluid connector (22) comprises at least one first lateral circular ring opening (42) defining the pump inlet (77) or the pump outlet (44). The fluid connector further comprises a separate second lateral circular ring opening (72) or a circular front opening (110) defining the pump outlet (44) or the pump inlet (77), wherein the pump outlet (44) and the pump inlet (77) are arranged coaxially to each other.

The present disclosure discloses a connection structure of an exhaust bearing seat for a compressor and a screw compressor, falling within the art of compressors, and designed to solve the problem of large radial vibration of the existing exhaust-end bearing seat. The connection structure of an exhaust bearing seat for a compressor disclosed in the present disclosure comprises an exhaust bearing seat, an oil separation bucket and an oil separation screen assembly all arranged at an exhaust end of a body of the compressor, wherein a tail end of the exhaust bearing seat is connected with the oil separation screen assembly, and an outer periphery of the oil separation screen assembly is provided with a vibration-reducing element, which is connected to an inner wall of the oil separation bucket. The vibration of the exhaust bearing seat is transmitted to the vibration-reducing element through the oil separation screen assembly, and then to the oil separation bucket after being absorbed by the vibration-reducing element, such that the tail portion of the exhaust bearing seat is obviously suppressed from radial vibration. Owing to the adoption of the above-mentioned connection structure of an exhaust bearing seat, the screw compressor provided in the present disclosure has reduced radial vibration at the exhaust-end bearing seat, and is rendered with longer service life and wider application scope.

Hydraulic pump unit (1) comprising a pump (2), a reservoir (3), multiple line connectors (99) and at least one valve seat (40) and a main body (5) including a channel system (50) having duct ends (502) which define multiple ports (52) in a common port face (51). The port face (51) of the main body (5) is a planar face of an outer surface of the main body (5). The pump unit comprises a function plate (6) which comprises a slotted passageway (60). The function plate (6) is placed to the port face (51) such that the slotted passageway (60) mates with at least two ports (52) to define a flow path in between these ports (52). An end body (9) sandwiches the function plate (6) between the port face (51) of the main body (5) and the end body (9) itself.

A vane pump 100 includes a rotor 2 that is rotationally driven; vanes 3 inserted into the rotor 2 in a freely slidable manner; pump chambers 6 that are defined between the vanes 3 at adjacent positions; suction ports 14 and 15 that guide working oil to the pump chambers 6; suction pressure chamber 13 that is communicated with the suction ports 14 and 15 and that stores the working oil; and a suction passage 12 that is connected to the suction pressure chamber 13 and that has an suction opening end 12a that opens at an outer surface of a pump body 10. In a state in which the vane pump 100 is mounted, the suction pressure chamber 13 is mounted below the suction opening end 12a of the suction passage 12.

A cartridge vane pump (100) includes: a body-side side plate (20) that is brought into contact with end surfaces of a rotor (2) and a cam ring (4); first and second discharge ports (7a) and (7b) that are formed in the body-side side plate (20); and an adapter (40) that is formed with first and second connection channels (41a) and (41b) for connecting the first and second discharge ports (7a) and (7b) formed in the body-side side plate (20) and first and second discharge channels (93a) and (93b) formed in a body (90).
摘要:
A submersible pumping apparatus for displacing transmission fluid includes a pump operably coupled with a motor. A filter housing is attached to the pump and has a cavity with an inlet aperture extending to an exhaust port of the pump. A fluid filter is engaged with the cavity and has a filter cover with a relief valve disposed within an outlet aperture that extends from the cavity to an exit port on the filter cover. The relief valve is configured to open when a fluid pressure from the exit port reaches a threshold and close when the fluid pressure is below the threshold. A rotor cover is attached to the motor and has a circuit board for operating the motor, such that the rotor cover is configured to prevent the circuit board from being exposed to liquid.

A pump including a pressure plate having two inlets and outlets, wherein each inlet has an auxiliary intake port in fluid communication with the inlet, and each outlet has an auxiliary discharge port in fluid communication with the outlet, and a cam/rotor assembly attached to the pressure plate. The cam/rotor assembly includes a rotatable cam having an opening, a rotor within the cam opening, the rotor having multiple radial slots, and multiple vanes that move within the slots, wherein a pumping chamber is defined by a space between rotor and cam. Rotor rotation within the cam causes the vanes to extend and retract within the pumping chamber. The movement of the vanes discharges into the outlets and auxiliary discharge ports a fluid drawn into the pumping chamber via inlets and auxiliary intake ports. The auxiliary inlet and auxiliary discharge ports reduce pressure pulsations in a variable displacement dual-lobe vane pump.

A pump includes a casing defining an interior volume. The pump casing includes at least one balancing plate that can be part of a wall of the pump casing with each balancing plate including a protruding portion having two recesses. Each recess is configured to accept one end of a fluid driver. The balancing plate aligns the fluid displacement members with respect to each other such that the fluid displacement members can pump the fluid when rotated. The balancing plates can include cooling grooves connecting the respective recesses. The cooling grooves ensure that some of the liquid being transferred in the internal volume is directed to bearings disposed in the recesses as the fluid drivers rotate.
