Abstract

An actuating apparatus has a first and a second actuating element that delimit a pressure chamber. The actuating apparatus has a rotary decoupling bearing coupled via a compensation assembly to the second actuating element for joint movement along the spatial axis. The compensation assembly comprises a first ramp element which is supported axially on the second actuating element and is preloaded relative to the second actuating element by a first preloading apparatus for rotation about the spatial axis and a second ramp element coupled to the rotary decoupling bearing. An axial overall length of the compensation group along the spatial axis changes in the case of a rotation, of the first ramp element relative to the second actuating element. The compensation assembly has a blocking element and a blocking toothing system in blocking engagement with a counter-blocking toothing system of the first ramp element
