  • Piston pump
    Patent number: 11261853
    Abstract: 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: Grant

  • Piston pump, particularly a high-pressure fuel pump for an internal combustion engine
    Patent number: 11168677
    Abstract: A piston pump, in particular high-pressure fuel pump for an internal combustion engine, includes a pump housing, a pump piston and a conveying chamber defined at least by the pump piston and the pump housing. A seal for sealing the conveying chamber and a separate guide element for guiding the pump piston may be arranged between the pump piston and the pump housing. The seal is designed as a metal sleeve, and may have a radially outwardly projecting web.

  • Piston pump comprising a piston with a profiled front face
    Patent number: 10781814
    Abstract: 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.
