    摘要: A regenerative pump apparatus has a housing and a substantially disc-shaped impeller rotatably housed by the housing. Circumferential rows of radial vane grooves are formed in the outer peripheral portions of both side surfaces of the impeller. Each circumferential row includes first vane grooves of an axial depth equal to or greater than a half of the impeller thickness and second vane grooves of an axial depth smaller than a half of the impeller thickness. The first and second vane grooves are arranged alternatingly in the circumferential direction in each row, such that the first vane grooves and the second vane grooves in one row are axially aligned with the second vane grooves and the first vane grooves in the other row.

    摘要: A rotary piston vacuum pump has a rotor eccentrically disposed in a cylinder and mounted therein for revolution in rolling contact with the cylindrical inner peripheral surface of the cylinder so that a crescent-shaped space is defined between the rotor and the cylinder and moved around the axis of the cylinder. A vane is radially reciprocally mounted in a vane chamber having an inner end open to the cylindrical inner peripheral surface of the cylinder. The vane has an inner end in sliding contact with the outer peripheral surface of the rotor to divide the crescent-shaped space into a suction chamber in communication with a suction port and a discharge port to be communicated with a discharge port having an inner end open in a wall of an outer part of the vane chamber. The rate of communication between the discharge port and the discharge chamber through the outer vane chamber part is varied by the reciprocal movement of the vane so that the communication is interrupted at least when the point of contact between the rotor and the cylinder inner peripheral surface reaches the vane.

    摘要: An electrically operated fuel pump apparatus comprises an electric motor and a regenerative pump having a pump housing and a disc-like impeller. The motor shaft has an end portion extending into a central axial through-hole formed in an end wall of the pump housing. A joint member comprising a ring-like base and a circumferential row of axial rods extending therefrom is rotatably disposed in the axial through-hole in the end wall of the pump housing and secured to the end portion of the motor shaft. The impeller is rotatably and axially movably mounted on an impeller shaft provided separately of the motor shaft and secured to the other end wall of the pump housing. The impeller is formed therein with a circumferential row of axial apertures with which the axial rods of the joint member loosely engage to transmit the rotation of the motor shaft to the impeller while permitting axial movement of the impeller relative to the motor shaft and the pump housing.

    摘要: An electric fuel pump for pumping a liquid fuel from a tank to an engine. The pump device has a regenerative pump section and an electric motor section for driving the regenerative pump section. The regenerative pump section includes a pump casing having a first inner surface and a second inner surface axially opposing to and spaced from each other to define therebetween a pump chamber, a shaft adapted to be rotatingly driven by the electric motor section and an impeller accommodated by the pump chamber and mounted on the shaft for rotation therewith but axially movably relatively thereto. The impeller has one axial end surface opposing to the first inner surface with a first gap formed therebetween, and the other axial end surface opposing to the second inner surface of the pump casing with a second gap formed therebetween. The first inner surface and the second inner surface of the pump casing has axial thrust generating surfaces which are so shaped as to gradually decrease the first and the second gaps towards the downstream sides as viewed in the direction of flow of fuel introduced into these gaps. In consequence, axial thrust forces are generated by wedging action of the fuel introduced into the gaps so that the impeller is kept out of contact with the inner surfaces of the pump casing during operation of the pump device.

    摘要: A fuel pump comprises a regenerative pump section, a driving section and a housing, the regenerative pump section being provided with a vapor vent for discharging fuel vapor. The vapor vent communicates with an outside of the fuel pump through a vent housing for a vortex flow. The vent housing has a vent chamber, a tangential groove and a discharge hole. A vortex flow of the fuel including the fuel vapor generates in the vent chamber and flows from the tangential groove to the discharge hole. When the fuel vapor does not generate, the vortex phenomenon is enhanced so that an amount of the fuel discharged from the discharge hole is reduced. The vent housing may have a radial control groove communicating with a control hole in addition to the tangential groove.

    摘要: A regenerative pump has a pump housing and a disc-like impeller mounted in the pump housing for axial movement therein and rotated by an electric motor. The impeller is provided with circumferential rows of vane grooves formed in the end faces of the impeller adjacent to the outer periphery thereof. The pump housing has inner surfaces closely spaced from the impeller end faces. Circumferentially continuous annular projections or circumferentially discontinuous projections are formed on either the impeller end faces or the housing inner surfaces to keep at least the major surface areas of the impeller end faces closely spaced from the mating inner surfaces of the housing. Axial passages extend through the impeller to equalize fluid pressures on the opposite impeller end faces.

The spring has at least two deflection modes, one of which shows a larger spring constant than the other deflection mode and appears in one of two valve positions. The controller outputs a relatively large force for displacing the valve elements to the valve position at which the spring is deflected at the larger spring constant.
