Abstract

A rotary actuator has a first rotatable part having a control surface with an undulating or sawtooth profile, and has a fixed second part having at least one detent element running on the control surface. The detent element is accommodated, in a manner which allows movement against a restoring force, in an aperture which tapers in a V shape towards the first part. The detent element is accommodated with play between the side walls bounding the aperture. The detent element interacts with the radially oriented control surface in such a way that, as it runs up a projection on the control surface as a result of a movement of the first part, it is moved against one side wall and, upon passing beyond the projection, strikes against the other side wall due the restoring force.
