An electric pump (2) draws and discharges fluid. When the fluid receives heat from the pump (2), the fluid has a saturation vapor pressure that can surpass the pressure of fluid that is drawn into the pump (2) and is lower than the pressure of fluid discha...

The pump has a membrane (50) with its peripheral end attached between a guiding body (20) and a hydraulic block. A piston (22) driving mechanism comprises a cam (42) having an eccentric cylinder that is driven, through intermediate gears, by an engine shaf...

The invention provides a fuel pump module for vehicle in which the overall length can be largely reduced and the vapor generated in the inside can be discharged to the outside. To achieve this, an electrically driven fuel pump 13 and a fuel filter 14 which...

The device has two electrical leads (11,12) leading to the motor and a suppression part (17) between the leads. The suppression part is a capacitor with a varistor connected in parallel with it in the form of a plate varistor or an envelope of fuel resista...

Permanent magnets (30, 31) are placed in both sides on the basis of a centerline of a rotor (16) perpendicular to a direction of a load applied to an impeller (4) by a pressure distribution within a pump flow path (7), and also an axial center (31a) of the...

A fuel injection system, comprising a low pressure fuel delivery pump (78) with constant output in fluid communication with a low pressure fuel line; said fuel line connected to an electronic controlled fuel pressure regulator (80) and fuel pressure sensor...

The fuel pump has surface regions sealed by the casing wall and pressurized from the side channel sectors. These surface regions (12, 13) are bounded by chambers (16, 17) formed in the axial walls (5, 6) of the pump wheel (4). They are subdivided by ribs i...
