Abstract

In a variable-capacity pump 1, of the type in which blades 5 are radially movable in a rotor 2, and in which there is around the rotor a number of pump chambers 9 mutually separate from the blades, a ventilating duct 19 belongs to each pump chamber. During a part of the revolution of the rotor 2, this duct can be connected to an opening 21, located in the pump housing 8, to a ventilating arrangement 20. <IMAGE>
