Patent number: 11261853Abstract: A piston pump, in particular a high-pressure fuel pump for an internal combustion engine, includes a pump housing, a pump piston, and a delivery chamber that is delimited at least by the pump housing and the pump piston. The piston pump further includes a seal configured to seal the delivery chamber and a separate guide element configured to guide the pump piston. The seal and the guide element are arranged between the pump piston and the pump housing. The seal is formed as a plastic ring with a substantially sleeve-shaped base portion.Type: GrantFiled: June 7, 2018Date of Patent: March 1, 2022Assignee: Robert Bosch GmbHInventors: Siamend Flo, Oliver Albrecht, Frank Nitsche, Andreas Plisch, Dietmar Uhlenbrock, Olaf Schoenrock, Jurij Giesler, Ekrem Cakir

Patent number: 10781814Abstract: The invention relates to a piston pump, in particular for injection systems for motorized two-wheeled vehicles and/or for motorized three-wheeled vehicles, having a compression chamber, a piston, an inlet valve, and an outlet valve. A fluid can flow into the compression chamber via the inlet valve, and the fluid can flow out of the compression chamber via the outlet valve. A region in the form of a channel, which is arranged fluidically upstream of the outlet valve, in particular directly upstream of the outlet valve, has a cross-section which is reduced compared to a compression chamber region at a distance from the outlet valve. The invention is characterized in that a piston end face facing the channel has a region which can be immersed into the channel.Type: GrantFiled: September 7, 2015Date of Patent: September 22, 2020Assignee: Robert Bosch GmbHInventors: Andreas Plisch, Jurij Giesler, Siamend Flo, Thorsten Allgeier, Walter Maeurer, Lena Maren Baessler

Patent number: 10619628Abstract: The present invention relates to a fuel pump (1) which comprises a pump housing (2), a delivery element (3) for delivering fuel, a heat-generating actuator (4) for actuating the delivery element (3), a first fuel path (5) which leads from an inlet (20) to a delivery space (7), and a second fuel path (6) which leads from the inlet (20) past the heat-generating actuator (4) to a first housing opening (21), wherein the first housing opening (21) is arranged above the inlet (20) in the vertical direction (V). The present invention also relates to a fuel pump arrangement which comprises a fuel pump (1) according to the invention and a fuel tank (10) in which the fuel pump (1) is at least partially and preferably entirely arranged. The present invention also relates to a method for operating a fuel pump (1).Type: GrantFiled: September 2, 2015Date of Patent: April 14, 2020Assignee: Robert Bosch GmbhInventors: Andreas Plisch, Frank Nitsche, Joerg Heyse, Siamend Flo, Thorsten Allgeier, Walter Maeurer, Tim Reule

Patent number: 10443587Abstract: A high-pressure fuel pump includes a pump housing with a housing wall and a damping device configured to damp inlet-side pressure pulses by varying a damping volume with an elastically deformable wall. At least one section of the elastically deformable wall is formed from one or more of at least one part of a jacket-like area of the housing wall and at least one part of a sealing support. The section is embodied such that it includes at least one main part configured to vary the damping volume.Type: GrantFiled: May 13, 2014Date of Patent: October 15, 2019Assignee: Robert Bosch GmbHInventors: Siamend Flo, Oliver Albrecht, Frank Nitsche, Thorsten Allgeier, Juergen Koreck, Andreas Plisch, Gerd Teike
