Abstract

A system for automatically metering liquid or paste-like auxiliary washing agents stored in reservoirs for automatically controlled washing machines. It has a central fluid line disposed in a housing bottom and a plurality of nozzles disposed in the housing bottom on a circular line extending concentrically to the axis of a rotor. The nozzles can be connected individually to the outlet by a connecting line inside the motor-drivable rotor. In the connection to the connecting line, seals are provided. Due to a force continually axially acting on the rotor in the direction of the housing bottom, said rotor presses the seals until the contact surfaces of the rotor and the housing bottom substantially form a common plane.
