Patent number: 11085407Abstract: In at least some implementations, a fuel supply module includes a reservoir and a fuel pump carried by the reservoir. The reservoir may include a body and a lid that define an internal volume to contain a supply of fuel, and the reservoir may include an inlet through which fuel enters the internal volume and an outlet from which fuel is discharged from the fuel supply module. The fuel pump is carried by the reservoir and has a first inlet communicating with the internal volume to take fuel into the fuel pump from the internal volume and a second inlet spaced above the first inlet relative to the direction of the force of gravity to take fluid or vapors into the fuel pump from the internal volume. The fuel pump includes an outlet from which fluid is discharged for delivery to an engine through the reservoir outlet.Type: GrantFiled: September 1, 2017Date of Patent: August 10, 2021Assignee: Walbro LLCInventors: Eric D. Anderson, Travis P. Baur, Elton J. Fisch, Cyrus M. Healy, Kevin L. Israelson, Gerald J. LaMarr, Jr., Robby L. Linton, Edward J. Talaski

Patent number: 11008987Abstract: A fuel pump for a fuel system includes a nozzle, a venturi, a pump inlet and a flow controller. The nozzle has an orifice through which fuel is ejected and the venturi is downstream of the nozzle and has an inlet through which fuel discharged from the orifice flows, a passage downstream of the venturi inlet through which fuel flows to create a drop in pressure in the area of the venturi, and an outlet through which fuel is discharged from the venturi. Fuel is drawn through the pump inlet by the drop in the pressure created in the area of the venturi and the flow controller is downstream of the outlet and has a chamber in which fuel from the venturi outlet is received. The flow controller causes fuel to fill the venturi to ensure performance of the fuel pump.Type: GrantFiled: February 26, 2014Date of Patent: May 18, 2021Assignee: WALBRO LLCInventors: Kenneth J. Cotton, Elton J. Fisch, David D. Hacker, Jeffrey D. Hanby, Kevin L. Israelson, Roger N. Smith
