摘要： An electric-operated fuel pump has a vaned impeller that is disposed within a pumping chamber for rotation about an axis. The pumping chamber has a main channel extending arcuately about the axis to one axial side of the impeller. The main channel has a radially outer margin that opens along at least a portion of the channel's arcuate extent to an adjoining contaminant collection channel which extends arcuately about the axis and which is effective, as the pumping element rotates, to collect certain fluid-entrained particulates expelled from the main channel and to convey such collected particulates toward the pump outlet. A sump is disposed at the end of the contaminant collection channel proximate the outlet. Several grooves in the seal surface between inlet and outlet, which is called “strip area.” The grooves are extended radially outward, the angles match the impeller vane angles and these grooves prevent leakage of the contaminations.

摘要： A vehicle regenerative-type fuel pump which reduces the possible accumulation and effects of contamination relative to impellers with outer ring members. The outer ring members have non-uniform configurations (slanted, curved, grooved, etc.) which reduce the affects of contamination which can cause wear and roughing of the outer surface resulting in higher torque and reduced pump efficiencies.

摘要： A non-corrosive fuel pump housing (36) that can be used in high-pressure applications and with aggressive or flex fuels. The fuel pump housing (36) is comprised of a pump cover (40) and pump body (38). The pump cover (40) and pump body (38) each have a narrow seal ring (101, 104), a cavity circle (103, 106), and a tapered seal ring (102, 105) extending radially from the narrow seal ring (101, 104) to the cavity circle (103, 106) that reduce friction between the impeller (34) and pump housing (36) and limit leakage between the impeller (34) and the pump housing (36). The pump housing (36) is composed of a thermosetting or thermoplastic material; as such material and manufacturing costs are less than traditional anodized aluminum pump housings.

摘要： A pump (10) has a housing containing an internal pumping chamber (30). A fluid inlet (32) and a fluid outlet (34) are spaced arcuately apart about an axis (12), and an impeller (20) within the housing rotates about the axis to pump fluid from the inlet to the outlet. The impeller has mutually parallel opposite faces (40, 42) circumferentially bounded by a vaned periphery (38). The impeller has a pattern of through-holes (46) extending between its faces and the one face that confronts a wall surface of the housing to which the inlet is proximate has, in association with each through-hole, a groove (44) that adjoins and tails circumferentially away from the respective through-hole in a sense opposite the sense in which the impeller rotates to pump fluid from the inlet to the outlet. The groove inclines and provides a reaction surface against which fluid exerts a lifting force to aid in force-balancing the impeller.

摘要： A fuel pump includes a housing, and a motor. An impeller has first and second impeller flow channels having a plurality of vanes positioned therein. The impeller defines a flow passageway extending through the impeller. A cover is attached to the housing and defines a cover flow channel. The cover flow channel receives fuel from an inlet formed in the cover. A first portion of the cover flow channel is aligned with the first impeller flow channel and a second portion of the cover flow channel is aligned with the second impeller flow channel. The cover flow channel extends around the cover more than 360 degrees. A body is positioned within the housing and defines an impeller chamber, sized to receive the impeller, and an outlet passageway is positioned to fluidically connect to the flow passageway of the impeller to receive higher pressure fuel for delivery to the engine.

摘要： A mechanical returnless fuel system comprises a fuel pump having an output for supplying fuel to fuel injectors of an automotive engine. The fuel system includes a pressure regulating valve that returns a portion of the pump output in excess of engine fuel usage to the fuel supply. The pressure regulating valve results in a fuel pressure that varies as a function of engine fuel demand. During operation, a controller determines a projected engine fuel demand, then determines an estimated fuel pressure based upon the projected engine fuel demand. The controller utilizes the estimated fuel pressure to provide a more accurate calculation of the opening time for the fuel injectors and thereby improve engine control.

摘要： A rotary fuel pump employs pressure balancing features on the non-vaned side of the impeller to provide localized application of fluid forces so that the impeller is more precisely balanced within the pumping chamber. A generally disc-shaped impeller body has an impeller with a body-side surface and a cover-side surface. The cover-side surface defines an impeller flow channel extending circumferentially around the impeller. The impeller includes a plurality of vanes positioned at least partially within the impeller flow channel. The body-side surface has a plurality of discontinuous undercut regions each coaxially aligned with at least a portion of the impeller flow channel. The impeller has a plurality of apertures wherein each aperture connects the impeller flow channel with a respective undercut region, whereby pressure forces against the impeller from the fuel are substantially balanced in the axial direction.
