Abstract:
A switching valve is described that has a stator which is arranged in a housing and which has multiple connection ports. The switching valve also has a rotatable rotor which is arranged in the housing and which, in predetermined switching positions defined by associated angular positions, interacts with the stator for the fluidic connection or separation of predetermined connection ports. The rotor is rotatably mounted, and acted on with a predefined pressing force in the direction of the stator, by means of a bearing and pressing device arranged in the housing. The bearing and pressing device has a spring device which exerts a load on the rotor or on an element that is capable of performing a wobbling movement.
