Abstract

Die Erfindung betrifft eine Pumpe (1), insbesondere eine Kühlmittelpumpe in einem Kraftfahrzeug, mit
- einem auf einem Pumpenwelle (2) angeordneten Laufrad (3),
- einem verstellbaren Schieber (4), der über das Laufrad (3) verschoben werden kann und dadurch eine Förderrate der Pumpe (1) regelt,
- einer ebenfalls auf dem Pumpenwelle (2) angeordneten Sekundärpumpe/Verdrängerpumpe (6), zum Aufbau eines den Schieber (4) steuernden Fluiddrucks,
- mit einer Ventileinrichtung (7), die eine Saugseite und eine Druckseite der Sekundärpumpe/Verdrängerpumpe (6) voneinander trennt oder verbindet und dadurch den von der Sekundärpumpe/Verdrängerpumpe (6) aufbaubaren Fluiddruck zum Verstellen des Schiebers (4) steuert.

The invention relates to a pump (1), in particular a coolant pump in a motor vehicle, with
an impeller (3) arranged on a pump shaft (2),
- An adjustable slide (4), which can be moved over the impeller (3) and thereby regulates a delivery rate of the pump (1),
a secondary pump / displacement pump (6) also arranged on the pump shaft (2), for establishing a fluid pressure controlling the slide (4),
- With a valve device (7) which separates a suction side and a pressure side of the secondary pump / positive displacement pump (6) from each other and thereby controls the secondary pump / positive displacement pump (6) buildable fluid pressure for adjusting the slide (4).
