Abstract
A valve for use in a coolant flow. The valve comprises a valve housing with an inlet and at least one outlet, a valve body which is rotatably received by the valve housing, an actuator for rotating the valve body, and a fail-safe mechanism which can be pretensioned rotationally. The valve body is in rotational engagement with an axially moveable coupling element, via which the valve body is releasably connected indirectly to the actuator shaft. In the event of a fault, the valve body can be decoupled from the actuator shaft by an axial movement of the coupling element. The axial movement of the coupling element also causes the fail-safe mechanism to come into rotational engagement with the coupling element in order to rotate the valve body to a predefined fail-safe position.
