Abstract (en)

[origin: EP1026401A2] The side plate(16) of the pump is loaded by a disc spring(30) in the direction of the displacement chamber, and the pump casing(2) is sealed on the end face side. The displacement component is a vane wheel. A rotor(6) is torsionally fixed on the shaft(4) and supports radially movable vanes(8), the end sections of which lie closely upon the inner circumference of a thrust ring(10) mounted in the pump casing. The side plate is preloaded against the thrust ring and cell wheel by the disc spring.
