Hydraulic system for actuating an interlocking switching element of a gearing device

A hydraulic system (1) for actuating an interlocking switching element (2) of a gearing device with two piston chambers (3, 4) and at least one double-action piston element (5) bounding the piston chambers (3, 4) is described. The piston element (5) can be subjected in the region of one of the piston chambers (4) to an actuating pressure (p_off) acting in the opening direction of the switching element (2) and in the region of the further piston chamber (3) to an actuating pressure (p_off) acting in the closing direction of the switching element (2). The actuating pressure (p_on, p_off) can be supplied to one or the other piston chamber (3 or 4) via a valve device (6), and the valve device (6) is actuable with a pilot control pressure (p_V) via an electrohydraulic actuator (7). According to the invention, the valve device (6) and the electrohydraulic actuator (7) are designed and operatively connected to each other in such a manner that, in the event of a drop in pressure, a hydraulic total force component act
