摘要： A motor pump unit with a multipart housing comprises a reversible internal gear machine and an electric motor with a rotor and a stator, which is coupled to the internal gear machine via a shaft rotatably mounted in the housing. One shaft end extends from the internal gear machine axially through the rotor that is carried by the shaft. First and second connecting channel ends in the working chamber of the internal gear machine are connected via check valves in the housing to a leakage channel loop, which is fluidically connected to a leakage channel that is fluidically connected to the working chamber, and which has a shaft leakage channel extending axially through the shaft and a rotor leakage channel that is fluidically connected thereto and extends axially through the rotor and/or a gap leakage channel between the rotor and stator, which is fluidically connected to the shaft leakage channel.

摘要： The invention proposes a vane pump (VP) with adjustable delivery volume, which vane pump has a pump housing (G), a cam ring (KR) arranged therein, and a rotor (R) which is rotatably movably mounted therein. The vane pump (VP) has a regulating device (RV) through which the delivered pressure medium (DM) flows and which has two outlets (A1, A2) which are each connected to one of two pressure chambers (DK1, DK2) in order to charge these with regulable proportions of the pressure medium (DM), wherein, to change the eccentricity of the cam ring (KR) relative to the rotor (R), the two pressure chambers (DK1, DK2) act on the outer surface of the cam ring (KR). The vane pump (VP) has two criss-crossing control ducts (STK*, STK#) which connect in each case one of the outlets (A1, A2) to one of the two pressure chambers (DK1, DK2) in order to charge these with the regulable proportions of the pressure medium (DM). The criss-crossing control ducts (STK*, STK#) are preferably arranged in a cover (D′) of the pump housing such that the control ducts (STK*, STK#) are in a criss-crossing arrangement without coming into contact with one another. By means of this design, the vane pump (VP) can be easily reconfigured for a change in rotational direction of the rotor.

摘要： A metering system for metering a liquid has an electric motor (32) for setting a desired feed rate, by modifying the rotation speed of the electric motor. It furthermore has an eccentric drive (52, 56), drivable by said electric motor (32), for a pump (53) that has two delivery directions. It also has a pump ring (62) made of an elastomeric material and a stationary ring (70) which is arranged relative to the pump ring (62) and to the eccentric drive (52, 56) in such a way that a pump chamber (120), extending in a circumferential direction, is formed between the stationary ring (70) and pump ring (62). The chamber changes shape upon rotation of the electric motor (32) in order to deliver a liquid to be metered through the pump chamber (120). A stationary seal (142) is provided in the pump chamber (120), between two fluid ports.

摘要： An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.

摘要： A roller vane pump that uses slippers on its rollers to create multiple seals. The roller vane pump has a fixed cam ring that has a rotor within. The rotor has openings that receive rollers that rotate about the inside of the cam ring. Each roller has a slipper rotatably connected thereto. The use of the slipper allows multiple seals to be created between the slipper, the rollers, and the cam ring and additionally allows for the roller vane pump to rotate clockwise or counterclockwise without the changing of parts.

摘要： A safe backspin device is provided to prevent uncontrolled backspin during operation of a progressive cavity pump. The safe backspin device has a bore and in one embodiment a ball that seats within the bore that act as a check valve. The check valve allows for unrestricted fluid flow in a normal flow direction. Fluid bypass ports allow for a restricted and controlled flow of fluid when the fluid direction of the progressive cavity pump is reversed from the normal flow direction. The bypass ports may be angled to clear sand buildup around an intake of the progressive cavity pump and in an annulus outside of a safe backspin device within a wellbore. In alternative embodiments a flapper valve may be used instead of a ball.

摘要： A pump system includes an inlet port, a discharge port, a drive aperture and a drain aperture. The drive aperture and the drain aperture are interchangeable such that the pump system may be utilized on either a clockwise or counterclockwise driven propeller. A propeller gearbox driven pump drive shaft is mounted into either aperture such that the aperture which receives the drive shaft becomes the drive aperture while the other aperture becomes the drain aperture. By allowing either pumping gear to become the driver gear by receiving the drive shaft, the pump system may accommodate either a clockwise or counterclockwise propeller gearbox.
