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.

Abstract: 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.

Abstract: A plunger fuel pump for an internal combustion engine includes a pump cylinder and a pump plunger that is axially displaceable in the pump cylinder. The plunger fuel pump has a seal with an annular basic structure arranged around the circumference of the pump plunger. The seal is produced by injection molding in an axial injection direction.

Abstract: The invention relates to a high pressure fuel pump for a fuel injection system of an internal combustion engine, having a pump housing in which is formed a working space, into which fuel can be supplied from a low pressure region of the radial piston pump, the working space being delimited by a pump piston which can be driven, in order to pressurize the fuel, by an external drive, in particular by a camshaft of an internal combustion engine, wherein in order to meter the fuel quantity supplied to the working space, a throttle device having a variable throttle action is arranged on or in the pump housing.

Abstract: A fuel system for an internal combustion engine includes at least one first fuel pump and a pressure region into which the fuel pump pumps and which communicates with an elastic volume reservoir. The elastic volume reservoir has a characteristic pressure/volume curve, which is defined by at least two points. It is proposed that a first point is defined by a first volume at a first pressure that is somewhat greater than a vapor pressure of the fuel at ambient temperature, and that a second point is defined by a second volume and a second pressure in the pressure region that corresponds to a maximum pressure; the difference between the first and second volumes corresponds at least approximately and at least to a value by which the volume of the fuel in the pressure region decreases upon cooling down from a maximum temperature to ambient temperature.
