Abstract
A switching valve includes a stator and a rotor. The stator includes multiple connection ports. The rotor has predetermined switching positions and interacts with the stator to form a fluidic connection or a fluidic disconnection of predetermined connection ports. The rotor can be mounted rotatably via a bearing and pressing device loaded with a predefined pressing force in a direction of the stator. The bearing and pressing device includes a compensation element to load the rotor and transmit the pressing force. The compensation element is configured to make an elastic flexural deformation so that the compensation element loads the rotor when the rotor is wobbling with respect to an axis of rotation.
