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.

Piston pump

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, particularly a high-pressure fuel pump for an internal combustion engine

The invention relates to a method for operating a piston pump, which is driven by means of a coil () of an electromagnet, wherein a piston () of the piston pump can be moved against a restoring force by means of the electromagnet, wherein a voltage (U) is applied to the coil () during a switch-on duration such that a current (I) flows through the coil () and the piston () is accelerated, wherein two different quenching methods are used for the current (I) in the coil ().

Method for operating a piston pump, control device of a piston pump, and piston pump

The present invention relates to a fuel pump () which comprises a pump housing (), a delivery element () for delivering fuel, a heat-generating actuator () for actuating the delivery element (), a first fuel path () which leads from an inlet () to a delivery space (), and a second fuel path () which leads from the inlet () past the heat-generating actuator () to a first housing opening (), wherein the first housing opening () is arranged above the inlet () in the vertical direction (V). The present invention also relates to a fuel pump arrangement which comprises a fuel pump () according to the invention and a fuel tank () in which the fuel pump () is at least partially and preferably entirely arranged. The present invention also relates to a method for operating a fuel pump ().

Fuel pump with improved delivery properties

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.

High-pressure fuel pump

An arrangement transmits a torque between a shaft and a hub. The hub has at least approximately the interior geometry of an equilateral n-sided polygon, the side surfaces of which at least approximately bear against a clutch portion, which is of circular overall cross section, of the shaft, and wherein the shaft has at least one driver portion which is rotationally conjoint with respect to the clutch portion and which extends in the direction of a corner of the n-sided polygon.
