Title (EN) PISTON PUMP
(FR) POMPE À PISTON
(DE) KOLBENPUMPE
Abstract:
(EN) The invention relates to a piston pump, in particular for a motor vehicle, comprising a piston (8) that is movably mounted in a housing, a linear actuator (4) for moving the piston (8) in a first direction, and a return spring (23) for moving the piston (8) in a second direction, the end face of a first end (10) of the piston (8) delimiting a first pressure chamber (11) that is associated with a first hydraulic circuit. According to the invention, the end face of a second end (18) of the piston (8) delimits a second pressure chamber (17).
(FR) L’invention concerne une pompe à piston, en particulier pour un véhicule automobile, avec un piston (8) monté de manière à pouvoir coulisser dans un boîtier, un actionneur linéaire (4) permettant de faire coulisser le piston (8) dans une première direction, et un ressort de rappel (23) permettant de faire coulisser le piston (8) dans une seconde direction, le piston (8) muni d’une première extrémité (10) délimitant, sur la face frontale, une première chambre de pression (11), qui est associée à un premier circuit hydraulique. Selon l’invention, le piston (8) muni d’une seconde extrémité (18) délimite, sur la face frontale, une seconde chambre de pression (17).
(DE) Die Erfindung betrifft eine Kolbenpumpe, insbesondere für ein Kraftfahrzeug, mit einem verschiebbar in einem Gehäuse gelagerten Kolben (8), mit einem Linearaktuator (4) zum Verschieben des Kolbens (8) in eine erste Richtung, und mit einer Rückstellfeder (23) zum Verschieben des Kolbens (8) in eine zweite Richtung, wobei der Kolben (8) mit einem ersten Ende (10) stirnseitig eine erste Druckkammer (11), die einem ersten Hydraulikkreis zugeordnet ist, begrenzt. Es ist vorgesehen, dass der Kolben (8) mit einem zweiten Ende (18) stirnseitig eine zweite Druckkammer (17) begrenzt.
