摘要

The contactor has a servo support (2) for a gear of a vehicle which is provided between an air supply (4) and the servo support facility (2) with reducing device (6) provided by a compressed air fed to limit. The reducer is directly connected to a component such that an element (10), depending on the position of the component (12) is mechanically influenced and that a servo pressure is adjusted and accordingly reduced.
