摘要： A circumferential flow type liquid pump has, and a pump casing including a pump base and a pump cover. The pump casing rotatably supports an impeller and defines an elongated arcuate pump flow path along the outer periphery of the impeller and a suction inlet and a discharge outlet at both ends of the pump flow path. A plurality of gas venting holes are formed in a sliding surface of the pump cover along the pump flow path and communicate with the outside of the pump. Bubbles formed in the fuel in the pump flow path are positively discharged out of the pump casing assembly, and no vapor lock is caused.

摘要： A fuel pump has a pump cover with an inlet through which fuel from a fuel tank is drawn by an impeller to a pumping chamber formed by a pump bottom and the pump cover. The inlet has divergent sides oriented such that fuel being pumped is routed radially outward of primary vortices in a section of the pumping chamber adjacent the inlet to a section of the pumping chamber opposite the inlet. In a first embodiment, the upper side of the inlet is oriented at approximately a 10 to 12 degree angle from the lower side. In a second embodiment, the upper side is oriented at approximately a 127 degree angle from a line parallel the shaft rotation, and the lower side is oriented at approximately a 139 degree angle from the same line.

摘要： A unit for delivery of fuel from the fuel tank to the internal combustion engine of a motor vehicle includes a feed pump which is arranged in the fuel tank and constructed as a flow pump with substantially circular-cylindrical impeller driven in rotation in a correspondingly circular-cylindrical pump chamber. In at least one of the two chamber end walls, at least one approximately annular delivery duct which is groove-like in cross section extends from a suction opening which opens into the pump chamber to a pressure opening leading out of the latter. This end wall of the chamber is penetrated in the region of the pressure opening by a bore hole connecting the pump chamber with a region of the system in which low pressure prevails. Gas bubbles can be removed from the pump and accordingly from the delivery path in a particularly reliable and simple manner in that this bore hole is situated in a sealing surface which defines the delivery duct in the radial direction with reference to the axis of rotation of the impeller.

摘要： An electric-motor tubine-vane fuel pump that includes a housing having a fuel inlet and a fuel outlet, and an electric motor with a rotor responsive to application of electrical power for rotating within the housing. A pump mechanism includes a turbine impeller coupled to the rotor for corotation therewith and having a periphery with a circumferential array of pockets. An arcuate channel surrounds the impeller periphery, and is operatively coupled to the fuel inlet and outlet of the housing for delivering fuel under pressure to the outlet. The impeller periphery is formed by a continuous uninterrupted serpentine rib of uniform peripheral thickness that extends at an angle back and forth between opposed axial side edges of the impeller periphery circumferentially around the impeller forming identical truncated pyramidal pockets alternating with each other around the impeller periphery on opposite side edges of the impeller.

摘要： A boiler feed pump including an elongate casing adapted to be interconnected in a pipeline and a variable speed electrical motor driving an axially extending shaft, which drives a condensate inducer pump and a multiple stage centrifugal pump, all of which are housed within the casing. The inducer pump comprises a series of axially spaced rotating annular disks which the condensate flows between. The centrifugal pump receives the condensate from the inducer pump and pumps it to a higher pressure suitable for feeding a boiler. The motor can operate at a variable speed to handle various flow demands. The motor also serves as a thrust balancing device for the multiple stage centrifugal pump.

摘要： A toric pump has a metal impeller housing formed with a flat end face into which an annular impeller receiving recess extends to a depth which exceeds the axial thickness of the impeller mounted in the recess by an amount only sufficient to provide a minimum operating clearance for the impeller sides when an impeller cover is mounted on the housing with a flat end face of the impeller cover in sealed face to face engagement with the flat end face of the housing. A bore in the impeller housing receives a cylindrical portion of the pump drive motor to accurately locate the rotary axis of the impeller with respect to the peripheral side surface of the stripper portion of the pump housing. All impeller-stripper portion clearances are established by machining of the die cast impeller housing and the formation of a flat surface on the impeller cover. A filter cover mounted upon the impeller cover cooperatively defines with the impeller cover an enclosed filter receiving chamber having an externally accessible inlet port opening into the chamber through the filter cover and a pump inlet passage opening from the filter chamber into a pump chamber recessed into the flat end face of the impeller cover. The impeller cover is formed with an externally accessible outlet port communicating with the pump chamber. A resilient block of filter media is enclosed in the filter chamber to filter air or other fluid flowing through the chamber from the inlet port to the pump inlet passage.

摘要： A vehicle fuel pump having an impeller on which close fins are formed continuously in the circumferential direction, and a motor supplied with a voltage from a vehicle power source to drive and rotate the impeller. A fuel in a pump chamber formed between the opposed surfaces of each adjacent a pair of close fins of the impeller is pressurized and forced out by the rotation of the impeller. The delivery pressure of the fuel pumped out of the fuel pump is set to a level higher than the pressure in an intake pipe communicating with the engine by about 2 to 3 kg/cm.sup.2, while the flow rate during engine operation is set to a range of 50 to 200 l/h. At least part of the side surface of one of each pair of close fins located on the downstream side with respect to the direction of rotation of the impeller is formed parallel to a plane perpendicular to the direction of rotation of the impeller, while an outer end portion of the side surface of the other close fin located on the upstream side is formed so as to be slanted relative to a plane perpendicular to the direction of impeller rotation so that the capacity of the pump chamber is increased, whereby the lowest flow rate in a state where the voltage supplied from the vehicle power source drops when the engine is started is set to 20 l/h or higher, thereby preventing engine starting failure.
