Abstract
A device for rendering a hydraulic actuating device operational. A motor vehicle clutch with an emitter-receiver system located in the transmission path of the actuating device comprising two pistons whose positions, relative to one another, can vary as a function of the desired operating behavior of the actuating device and is developed further such that in relation to the emitter-receiver system that is to be filled with fluid, operationality can be established comparatively quickly and by simple way. A fluid supply unit () comprises one impulse valve () that serves to release an essentially constant volume flow, acted upon by an impulse valve control device () which is constructed such that the fluid volume flow released by the fluid supply unit () and flowing into the emitter-receiver system () does not exceed a limiting volume flow Q.
