摘要： A pump for supplying gasoline to the fuel injectors of an automotive engine includes a pump case, and upper and lower pump housings mounted within the case and forming an annular pumping channel. The pumping channel includes a vapor channel extending along an axially enlarged section of the bottom portion of the pumping channel from the pump's inlet to a purge orifice which extends axially through the lower pump housing from a radially inward portion of the pumping channel.

摘要： A fuel pump has a motor (14) with a shaft (18) extending therefrom and an impeller (20) fitted thereon for pumping fuel from a fuel tank to an internal combustion engine. A pumping chamber (36), which encases the impeller (20), is comprised of a cover channel (38) and a bottom channel (40) formed in a pump cover (24) and a pump bottom (22), respectively. The impeller (20) has a plurality of radially extending vanes (50) on an outer circumference separated by partitions (56) of shorter radial length. The partitions are comprised of substantially quarter-circle shaped arcuate portions (60) extending from the outer circumference of the impeller (20) to a diverging portion, preferably to a substantially flat top (66) with rounded corners (67). Fluid active vane grooves thus formed circumferentially between the vanes (50) and axially between the partitions (60) which reduce fuel vortices angular acceleration within the pumping chamber (36) thus increasing pump efficiency.

摘要： A regenerative turbine impeller comprises an annular disk having an annular partition wall extending radially therefrom. A first plurality of circumferentially spaced turbine vanes provided on one side of the partition wall radially projecting from the annular disk and have a radial length greater than the partition wall. A second plurality of circumferentially spaced turbine vanes circumferentially spaced about the disk extend radially therefrom and are provided on a second side of the partition wall. The second plurality of vanes rotationally staggered with respect to the first plurality of turbine vanes.

摘要： The housing has two portions forming a cover (40) and a bottom (38). The cover has an inlet port defining a directional control surface having an inclined frusto-conical portion and an inclined planar portion joined and laterally extending from it to radially accelerate the fuel. The bottom has an annular bottom channel which, when the cover and bottom are assembled defines with the cover channel (54), a flow inlet channel. A transition section is located at the beginning of the inlet channel and extends along a portion of the arc of the inlet channel.

摘要： A pumping chamber main channel (42) has a radially outer margin that opens along at least a portion of the channel's arcuate extent to an adjoining contaminant collection channel (56) which extends arcuately within the housing and which is effective as the vaned impeller (28') rotates, to collect certain fluid-entrained particulates expelled from the main channel and to convey the collected particulates towards an outlet of the pumping chamber.

摘要： A gerotor pump includes a pair of relief ports superimposed on and directly communicating with the pump's inlet and outlet channels, respectively. The relief ports simultaneously communicate with an open mesh pumping chamber so as to provide an intermittent controlled leak from the open mesh pumping chamber. Upon rotation of the gear members of the gerotor pump when the volume in the open mesh pumping chamber is increasing to a maximum volume, fluid in the open mesh pumping chamber vents into the relief port superimposed on and communicating with the outlet channel while continuing to communicate with the relief port superimposed on and communicating with the inlet channel. Upon further rotation of the gear member when the volume in the open mesh pumping is decreasing, fluid in the open mesh pumping chamber is prevented from venting into the relief port superimposed and communicating with the inlet channel while continuing to communicate with the relief port superimposed on and communicating with the outlet channel. Thus, fluid over-pressure in an excessive fluid leakage from the open mesh pumping chamber is limited.

摘要： A fuel pump has a motor mounted within a housing with a shaft extending therefrom to which a helically shaped impeller is fitted for pumping fuel from a fuel tank to an automotive engine. An end section of the housing has an inlet leading from the fuel tank to a pre-swirl fuel channel or trough located at the radially outermost perimeter of an impeller mating face on the end section. The trough has an inlet ramp which routes fuel to an inclined section with an axial grade to force the fuel to flow in the direction of impeller rotation. A trough termination ramp between the inclined section and the inlet ramps fuel toward the impeller at a steeper grade than the inclined section such that the fuel trough becomes flush with the impeller mating face. Fuel can thus be picked-up by the impeller throughout at least 340 DEG of rotation.
