Claims (7)

1. Kolbenpumpe zur Fluidförderung, mit einem frei schwimmenden Pump-Kolben (12) in einem Zylinder­ gehäuse (14), wobei
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.
2. Kolbenpumpe nach Anspruch 1, dadurch gekennzeich­ net, daß das Zylindergehäuse einen Kolben-Posi­ tionsgeber (37, 38) aufweist, der an einer Kolben- Endposition durch den Kolben (12) betätigt wird und ein Umschalten der Ventilvorrichtung (27, 29) auslöst. 2. Piston pump according to claim 1, characterized in that the cylinder housing has a piston position transmitter ( 37 , 38 ) which is actuated at a piston end position by the piston ( 12 ) and a switching of the valve device ( 27 , 29 ) triggers.
3. Kolbenpumpe nach Anspruch 2, dadurch gekennzeich­ net, daß zwei Kolben-Positionsgeber (37, 38) an beiden Kolben-Endpositionen vorgesehen sind, die wechselseitig ein Umschalten der Ventilvorrichtung (27, 29) auslösen.3. Piston pump according to claim 2, characterized in that two piston position sensors ( 37 , 38 ) are provided at both piston end positions, which mutually trigger a switching of the valve device ( 27 , 29 ).
4. Kolbenpumpe nach einem der Ansprüche 1-3, dadurch gekennzeichnet, daß das Federelement (19) eine Druckfeder in der Steuerkammer (18) zwischen dem Kolben (12) und dem Zylindergehäuse (25) ist.4. Piston pump according to one of claims 1-3, characterized in that the spring element ( 19 ) is a compression spring in the control chamber ( 18 ) between the piston ( 12 ) and the cylinder housing ( 25 ).
5. Kolbenpumpe nach Anspruch 4, dadurch gekennzeich­ net, daß der Kolben (12) eine konkave Ausnehmung (13) aufweist und die Druckfeder (19) spiralförmig . ausgebildet ist, so daß sie in zusammengedrücktem Zustand teilweise die konkave Kolben-Ausnehmung (13) ausfüllt.5. Piston pump according to claim 4, characterized in that the piston ( 12 ) has a concave recess ( 13 ) and the compression spring ( 19 ) spiral. is formed so that it partially fills the concave piston recess ( 13 ) in the compressed state.
6. Kolbenpumpe nach einem der Ansprüche 1-5, dadurch gekennzeichnet, daß der Hubraum des Kolbens (12) ein definiertes Volumen zum Fördern einer defi­ nierten Fluidmenge bei einem Kolbenhub hat.6. Piston pump according to one of claims 1-5, characterized in that the displacement of the piston ( 12 ) has a defined volume for delivering a defi ned amount of fluid during a piston stroke.
7. Kolbenpumpe nach einem der Ansprüche 1-6, dadurch gekennzeichnet, daß die Pumpe in einem Fahrzeug zum Pumpen von Schmieröl vorgesehen ist, wobei die Unterdruckleitung (32) mit dem Ansaugtrakt (52) eines Verbrennungsmotors (50), der Fluideinlaß (22) mit einem Ölvorrat (54) und der Fluidauslaß (20) mit einem Ölverbraucher (56) verbunden ist.7. Piston pump according to one of claims 1-6, characterized in that the pump is provided in a vehicle for pumping lubricating oil, the vacuum line ( 32 ) with the intake tract ( 52 ) of an internal combustion engine ( 50 ), the fluid inlet ( 22 ) is connected to an oil reservoir ( 54 ) and the fluid outlet ( 20 ) is connected to an oil consumer ( 56 ).
