Abstract

A device for actuating a locking mechanism, in particular for actuating a parking lock of a vehicle having an automatic transmission. The device comprises a piston which axially moves, a retaining device which is self-activating when the piston is in an axial position in which the locking mechanism is open to hold the piston in the axial position in which the locking mechanism is open, and an actuating device for actuating a release element, which deactivates the retaining device. To hold the piston in an axial position in which the locking mechanism is closed, the retaining device is self-activating, and can be deactivated to enable the piston to move, starting from the axial position in which the locking mechanism is closed, to the axial position in which the locking mechanism is open.
