摘要： A distributor assembly (12) includes a distributor housing (102) and a valve selector plate (104). The distributor housing (102) includes an axial bore (106) extending in an axial direction through the distributor housing. The valve selector plate (104) is disposed in the axial bore (106) and is rotatable around a rotational axis (130) parallel to the axial direction between a first orientation and a second orientation. The valve selector plate (104) includes a first substantially planar face (132), a second substantially planar face (134), axial passages (136) radially offset from the rotational axis (130) and extending through the valve selector plate (104) from the first face (132) to the second face (134), and at least one fluid blocking section (138) configured to block axial flow through the distributor assembly. Each fluid blocking section (138) is interposed between and radially aligned with the axial passages (136) with respect to the rotational axis (130). A two-speed gerotor motor is also disclosed.

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： Fuel pump 10 includes a filter 42 that rests on ledge 48, between the pump housing 12 and inlet cap 56. Filter detector 50 has a valve engager stem 62 for opening the check valve 58 and bearing feet 52 that engage the perimeter of the filter but the bearing feet are out of alignment with the ledge. When the filter is absent from the pump, the bearing feet 52 of the valve engager move beyond the ledge 48 and the valve engager stem 62 retracts from the check valve 58 and the valve closes to terminate flow of fuel to the pump, thus limiting the fuel that can escape from then pump when it is opened. At least one of the inlet and outlet caps 56 and 76 are rotatably mounted to the intermediate body of the pump to allow the fuel inlet and outlet to be oriented at angular intervals about the pump to facilitate the connection of fuel lines to the pump.

摘要： The present invention relates to an internal gear pump (1) for controlling the slip of a hydraulic vehicle brake system. The present invention suggests that a check valve (24) for connecting the pressure chamber (9) of the internal gear pump (1) to a pump discharge unit is integrated with an axial directional disk (12) of the internal gear pump (1). The check valve (24) prevents the drop of braking pressure due to the flow of fluid in the internal gear pump (1) when a vehicle brake system is operated without the drive of the internal gear pump (1).

摘要： The present invention corresponds to a check valve with an inertial mass that is installed in the bottom of the production tubing and above the progressive cavity pump (PCP) of an oil well, which prevents that the hydrostatic column that is inside of the production tubing go down in the moment where the artificial lift of the column stops for the detention of the PCP pump. If we prevent that this phenomenon to happen, the PCP pump will not rotate in the opposite direction of its normal operation and it will not be clogged by any particulate material that is contained in it.
