Claims (7)
das Zylindergehäuse (14) auf einer Seite des Kol bens (12) eine Pumpkammer und auf der anderen Sei te des Kolbens (12) eine Steuerkammer (18) auf weist,
die Pumpkammer (16) einen Fluideinlaß (22) mit einem ersten Rückschlagventil (23) und einen Fluidauslaß (20) mit einem zweiten Rückschlagven til (21) aufweist,
die Steuerkammer (18) einen Unterdruckanschluß (26) und einen Belüftungsanschluß (28) aufweist, die beide durch eine Ventilvorrichtung (27, 29) gesteuert werden, und
der Kolben (12) mit einem Federelement (19) in Richtung der Pumpkammer (16) axial vorgespannt ist und bei Steuerkammer-Unterdruck gegen die Feder kraft des Federelementes (19) in Richtung der Steuerkammer (18) bewegt wird.1. Piston pump for fluid delivery, with a freely floating pump piston ( 12 ) in a cylinder housing ( 14 ), wherein
the cylinder housing (14) on one side of the spool (12) having a pumping chamber and on the other te Be of the piston (12) a control chamber (18) comprises,
the pump chamber ( 16 ) has a fluid inlet ( 22 ) with a first check valve ( 23 ) and a fluid outlet ( 20 ) with a second check valve ( 21 ),
the control chamber ( 18 ) has a vacuum connection ( 26 ) and a ventilation connection ( 28 ), both of which are controlled by a valve device ( 27 , 29 ), and
the piston ( 12 ) is axially biased with a spring element ( 19 ) in the direction of the pump chamber ( 16 ) and is moved in the direction of the control chamber ( 18 ) against the spring force of the spring element ( 19 ) when the control chamber is under pressure.
