Patent number: 11898523Abstract: A fuel system that provides fuel to an internal combustion engine includes a fuel tank and a fuel pump configured to receive fluid from the fuel tank and supply pressurized fluid to the engine via a fuel filter. The filter receives fuel from the pump and provides filtered fuel to the engine. The filter is disposed in a filter chamber of a filter housing. The filter housing includes a fuel inlet that directs fuel received from the fuel pump into the filter chamber, a fuel outlet that directs filtered fuel received from the fuel filter to the fuel supply line, and a bypass outlet that directs fuel not drawn into the fuel filter by the internal combustion engine to a fuel pressure regulator. The regulator receives the unfiltered fuel from the bypass outlet and returns the unfiltered fuel to the fuel tank.Type: GrantFiled: August 5, 2022Date of Patent: February 13, 2024Assignee: Robert Bosch GmbHInventors: Paul Mason, Alberto Levi Rossano Ruiz, David Toutant

Patent number: 10309424Abstract: A vehicle fuel pump module includes a jet pump assembly and feed tube that delivers fuel to the assembly. The module includes a jet pump choke that is disposed in the jet pump assembly and provides a reduction of pressure of fluid within the jet pump assembly. The jet pump choke includes include a choke housing that defines a passageway that extends between a fluid inlet and outlet, and a slot that is formed in a surface of the passageway. A ball is fixed within and obstructs the passageway, and abuts the slot. A fluid path defined between the ball and surfaces of the slot provides fluid communication between the fluid inlet and outlet of the choke housing.Type: GrantFiled: November 20, 2017Date of Patent: June 4, 2019Assignees: Robert Bosch LLC, Robert Bosch GmbHInventors: Paul Mason, David Toutant

Publication number: 20190153983Abstract: A vehicle fuel pump module includes a jet pump assembly and feed tube that delivers fuel to the assembly. The module includes a first choke and a second choke. The first choke is disposed in the feed tube and provides filtering of the fluid and a reduction of pressure within the feed tube. The second choke is disposed in the jet pump assembly and provides a reduction of pressure of fluid within the jet pump assembly. The first and second chokes each include a choke housing that defines a passageway that extends between a fluid inlet and outlet, and a slot that is formed in a surface of the passageway. A ball is fixed within and obstructs the passageway, and abuts the slot. A fluid path defined between the ball and surfaces of the slot provides fluid communication between the fluid inlet and outlet of the choke housing.Type: ApplicationFiled: November 20, 2017Publication date: May 23, 2019Inventors: Paul Mason, David Toutant

Patent number: 9982640Abstract: A fuel supply system includes a fuel pump having an inlet configured to pick up fuel and an outlet configured to discharge fuel. A pressure vessel is in fluid communication with the outlet of the fuel pump such that fuel is directed from the fuel pump into the pressure vessel, the pressure vessel having an outlet port. A pressure regulation valve subassembly is detachably coupled with the outlet port via a male-female interface that positively locks against axial separation upon axial coupling in a first orientation and relative rotation of less than 360 degrees to a second orientation. A reservoir defines an internal space at least partially receiving the fuel pump, the pressure vessel, and the pressure regulation valve subassembly. The reservoir includes an interior wall that obstructs rotation of the pressure regulation valve subassembly from the second orientation to the first orientation.Type: GrantFiled: August 25, 2015Date of Patent: May 29, 2018Assignee: Robert Bosch GmbHInventors: Paul Mason, David Toutant, Tommy Ristovski
