Abstract: A casing for a fluid pump is provided. The casing includes a unitary, single-piece, elongated shell having opposite first and second open ends. A circumferential bead is formed in the shell. A sleeve is received in the first open end of the shell. The sleeve is disposed between the bead and the first open end. A heat sink cap is received in the first open end and engages the sleeve. The shell includes a crimp formed at the first open end. The crimp contacts the heat sink cap and retains the heat sink cap in the first open end. The shell includes a lip formed at the second open end. A motor section and at least a part of a pumping section of the pump are encapsulated within the shell between the lip and the crimp. A fluid pump and a method of encapsulating the fluid pump are also provided.

Abstract: A fluid pump includes an inlet plate and an electric motor. The electric motor has a shaft that rotates about an axis. A pumping arrangement is rotationally coupled to the shaft. The pumping arrangement includes an rotating element. The fluid pump further includes a thrust bearing driver including a disc-like plate having first and second faces, and two posts extending perpendicularly from the first face. The shaft has a terminal end including a pair of slots that cooperate with the posts of the thrust bearing driver. The inner gear rotor has an inner surface including a pair of slots that cooperate with the posts of the thrust bearing driver. The posts of the thrust bearing driver are received in the slots of both the shaft and the rotating element, and the thrust bearing driver is sandwiched between the shaft, the inlet plate, and the rotating element.

Abstract: A fluid pump includes a rotor which is centered about an axis, the rotor having a rotor central chamber and a plurality of vane slots. A stator has a recess therein within which the rotor is located, the recess having a recess peripheral surface which is eccentric to the axis. Each vane slot includes a vane therein such that the vanes define a plurality of pumping chambers which expand and contract based on rotational position the rotor relative to the stator. A positioning ring is located within the rotor central chamber such that the positioning ring engages each vane and such that the positioning ring urges each vane into contact with the recess peripheral surface. The positioning ring is radially aligned with a midpoint of each vane.

Abstract: A fuel pressure regulator includes a fuel inlet; a fuel outlet; a seating surface; and a valve member assembly. The valve member assembly includes a poppet and also includes a sealing member which is made of an elastomer material and which is annular in shape and including a sealing member surface. The sealing member is supported by the poppet. The valve member assembly is moveable between 1) a closed position in which the sealing member surface engages the seating surface, thereby preventing fuel flow from the fuel inlet to the fuel outlet and 2) an open position in which the sealing member surface is spaced apart from the seating surface, thereby allowing fuel flow from the fuel inlet to the fuel outlet.

Abstract: A positive displacement fluid pump is provided. The fluid pump includes a housing defining an internal cavity. A motor having a drive shaft that rotates about an axis is housed within the internal cavity of the housing. An internal plate is adjacent the motor and includes a central bore through which the drive shaft extends. The fluid pump further includes an external plate including an inlet in fluid communication with a suction port and an outlet in fluid communication with a delivery port. A pumping ring is sandwiched between the internal and external plates, and a pumping arrangement is located within the pumping ring and axially between the internal plate and the external plate. The pumping arrangement is rotatably coupled to the drive shaft such that rotation of the pumping arrangement by the drive shaft causes fluid to be pumped from the suction port to the delivery port.

Abstract: A sealing ring gland receives a sealing ring. The sealing ring gland includes an inner wall surface which seals against an inner periphery of the sealing ring. An outer wall surface is radially offset from the inner wall surface and seals against an outer periphery of the sealing ring. The sealing ring is axially compressed between an upper wall surface and a lower wall surface of the sealing ring gland. At least one of the upper wall surface and the lower wall surface includes an expansion volume which provides space for the sealing ring to expand upon swelling of the sealing ring.

Abstract: A fuel pump includes a housing which is tubular; an inlet plate closes one end of the housing and an end cap closes the other end of the housing. The end cap includes an outlet passage and a vapor purge passage. An electric motor within the housing rotates a pumping element to pump fuel through the fuel pump. A valve assembly of the fuel pump includes a valve member located within the purge passage, the valve member being moveable between a first position which blocks fluid communication therethrough and a second position which provides fluid communication therethrough. A valve retainer fixed to the end cap includes a first leg, a second leg which is opposed to the first leg, and a cross-beam which joins the first leg and the second leg. The valve member is stopped by the cross-beam at the second position.
