Abstract:
A starting control for the control of a hydraulic piston/cylinder unit (100), in particular for the control of a multi-disc clutch (101), havinga control valve (10) which is movable into an open and a closed position;a first connecting line (22) which can be connected to the hydraulic piston/cylinder unit (100) and a second connecting line (20) which can be connected to a pressure feed (P);with the first (22) and the second (20) connecting line being in communication with the control valve (10),and with the first connecting line (22) being designed in such a way that when it is subjected to pressure, a force acting in the closed position can be generated on the control valve (10);a first control line (24) which is in communication with the control valve (10) in such a way that when it is subjected to pressure a force acting in the open position can be generated on the control valve (10), and havinga restrictor element (30) whose inlet (32) is structured and arranged to be connected to the pressure feed (P) and whose outlet (34) is in communication with a pressure store (40) in one direction and with the first control line (24) and, in another directionwith the control valve (10) being structured and arranged such that it is moved from the open position into the closed position when the pressure force acting in the first connecting line (22) exceeds the pressure force acting in the first control line (24) by a given amount.
