摘要： An electric control system for an automobile transmission includes an endless transmission member running on a pair of V-shaped pulley units, the mutual distances of the conical sheaves of which are hydraulically adjustable to transmit an output torque of an engine to a driven apparatus. The electric control system is arranged to determine an optimum fluid pressure in relation to the actual output torque of the engine and to determine an optimum transmission ratio for low fuel consumption in relation to the actual output power of the engine. The control system produces a first electric control signal indicative of the difference between the optimum fluid pressure and the actual fluid pressure in one of actuators for the respective pulley units and produces a second electric control signal indicative of the difference between the optimum and actual transmission ratios. The pressure of fluid applied to one of the actuators is controlled in response to the first electric control signal, and the flow quantity of fluid applied to the other actuator is controlled in response to the second electric control signal.

摘要： A fuel pump apparatus has an electric motor and a regenerative pump having a pump housing and an impeller rotated by the motor shaft journalled by a bearing to the pump housing. The impeller is operative to produce in the pump housing a fluid pressure which is unbalanced in the circumferential direction of the impeller and forms circumferentially unbalanced radially inward forces the resultant force of which is applied through the impeller to a first side of the peripheral surface of the shaft. The discharge port of the pump is open to the interior space within the motor. An opening is formed in the bearing and has an inner end faced to a second side of the peripheral surface of the motor shaft substantially diametrically opposite to the first side, whereby the discharge pressure of the pump is applied through the motor interior space and through the opening in the bearing to the second side of the motor shaft to counterbalance to the resultant force of the circumferentially unbalanced radially inward forces applied to the motor shaft.

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 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.

摘要： A regenerative pump has a pump housing and a disc-like impeller mounted in the housing so as to be rotated by a motor. The impeller is provided with circumferential rows of radial vane grooves formed in the opposite end faces of the impeller adjacent to the outer periphery thereof. The rows of grooves are surrounded by a circumferential fluid passage which is formed between the impeller and the pump housing and communicated with suction and discharge ports formed in the pump housing and open to the circumferential fluid passage adjacent to the outer peripheral edges of respective end faces of the impeller. Each of the vane grooves has a bottom face which is arcuate as viewed in a radial section of the impeller. The suction port is substantially tangential to the bottom face of each vane groove in the adjacent end face of the impeller at the junction between the groove bottom face and the end face of the impeller.
