Abstract: A dual outlet washer pump for an automotive vehicle to alternately supply a stream of washer fluid to separate locations has a valve element with a frame portion surrounding a flat, flexible membrane mounted in vertically plainer fashion in a discharge section, which is movable from a center position unobstructing either of a pair of discharge ports to a first position in which fluid flow from a pumping chamber enters a first discharge side of the discharge section to directly impact a first side of the membrane causing flexure thereof away from the first discharge port to fluid flow there through and can currently causes contact of a second side of the membrane within an inner, lateral side of the discharge section adjacent the second discharge port to block fluid flow there through, the membrane opening the second discharge port and closing the first discharge port in the like manner when an impeller pump is rotated in a counter direction.

Abstract: An electric-operated fuel pump (20) has a vaned impeller (28, 28') that is disposed within a pumping chamber (27) for rotation about an axis (21). The pumping chamber has a main channel (42) extending arcuately about the axis to one axial side of the impeller. The main channel has a radially outer margin that opens (58) along at least a portion of the channel's arcuate extent to an adjoining contaminant collection channel (56) 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 (40). A sump (72) is disposed at the end of the contaminant collection channel proximate the outlet. The impeller (28') has a ring (70) girdling the impeller vanes (52) with a radially inner surface that is slightly concave in axial cross section.

Abstract: A fuel pump has a motor which rotates a shaft with an impeller fitted thereon for pumping fuel within a pumping chamber comprised of semi-elliptically shaped flow channels formed in a pump cover and a pump bottom which encase the impeller. Primary vortices developed by the rotary pumping action of the impeller closely approximate the shape of the pumping chamber thus minimizing secondary counterflowing vortices with their attendant decrease in pump efficiency. An alternative design is the special case of an ellipse where the major axis and the minor axis of the ellipse have equal lengths such that the pumping chamber has semi-circular shaped flow channels.

Abstract: A method for operating fuel system that supplies fuel to a plurality of injectors in an internal combustion engine via a first pump and a second pump with a bypass circuit coupled between the first and second pump for returning fuel to a fuel tank, the pumps connected in series, is provided. The method includes before actuating fuel injectors during an engine start, operating the first pump, where fuel is driven through the bypass circuit that generates a fuel pressure that is delivered to the injectors that is greater than the fuel pressure delivered to the injectors during the moderate pressure mode of operation when the bypass regulator is maintaining a constant fuel line pressure. The method also includes during actuation of the fuel injectors after an engine start, operating the first and second pumps, where fuel pressure is regulated at a specified regulator pressure via bypass flow in the bypass.

Abstract: A fuel delivery module for an automotive fuel delivery system includes a reservoir and a fuel pump. The fuel pump delivers fuel from the tank to the reservoir via a fuel tank inlet and reservoir outlet and from the reservoir to the engine via a reservoir inlet and engine outlet. The reservoir is formed with a plurality of contaminant traps for collecting contaminants contained in the fuel as the fuel is pumped through the reservoir such that the contaminants settle unto said contaminant traps thereby reducing the amount of contaminants entering the reservoir inlet.

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

Abstract: 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.
