<p>A clutch actuation device in a motor vehicle is to be capable of being controlled by a clutch pedal and additionally and independently by a one-way clutch. At the same time it is proposed to provide, in addition to a clutch pedal (12), a hydraulic auxiliary piston (2) connected to a two-way valve (15), controllable by the one-way clutch, which piston acts on the means, such as a fluid column or a Bowden cable or the like, actuating a clutch lever (23). The clutch can thereby be opened by the hydraulic auxiliary piston (2) independently of the clutch pedal (12). In order to trigger the hydraulic auxiliary piston (2) the two-way valve (15) is actuated by means of two electromagnets (18 and 19), a displacement (7) of the auxiliary piston (2) being connected either to a pressure line (17) of a pressure source or to a discharge line (16). <IMAGE></p> |
