Abstract

The invention relates to a parking lock device (68) for a motor vehicle, comprising at least one actuating unit (69), provided for the actuation of a parking lock, and at least one evacuation slide (100) having at least one pressure chamber (106) with at least one actuation terminal (108) connected to the actuating unit (69). The evacuation slide (100) has at least one control surface (114) associated with the pressure chamber (106), said surface being provided in order to supply a switching force that is dependent on a working fluid pressure in the pressure chamber (106).
