Piston pump

The invention relates to a piston pump (16), in particular a high-pressure fuel pump for an internal combustion engine, comprising a pump housing (26), a pump piston (28) and a delivery chamber (38) delimited at least by the pump piston (28) and the pump housing (26). It is proposed that a seal (44)...

Beschreibung
Zusammenfassung:	The invention relates to a piston pump (16), in particular a high-pressure fuel pump for an internal combustion engine, comprising a pump housing (26), a pump piston (28) and a delivery chamber (38) delimited at least by the pump piston (28) and the pump housing (26). It is proposed that a seal (44) for sealing the delivery chamber (38) and a separate guide element (46) for guiding the pump piston (28) are arranged preferably between the pump piston (28) and the pump housing (26), the seal (44) being designed as a plastic ring having a substantially sleeve-shaped base section (45). 本发明涉及一种塞泵(16)，尤其是用于内燃机的燃料高压泵，具有泵壳体(26)、泵活塞(28)和至少由所述泵活塞(28)和所述泵壳体(26)限界的输送室(38)。本发明提出，优选在所述泵活塞(28)和所述泵壳体(26)之间布置有用于密封所述输送室(38)的密封件(44)和用于对所述泵活塞(28)导向的单独的导向元件(46)，其中，所述密封件(44)构造为塑料环，其具有基本上套筒形的基础区段(45)。
