Hydraulische Steuerung für schaltbare Verbindungselemente, insbesondere für eine fremdgeschaltete Kupplung an einem Antriebsmotor

摘要

A pump (P) produces an oil flow, the path of which is determined by a distributing valve (WV) and contains a choke (2) as a gauge. A regulating valve (RV) is connected to the inflow and outflow (3,4) of the flow path (1) of the first choke before and after it and has a regulator piston (6) moving against spring force (5). A control groove (7) on the regulator piston co-operates with a branch (10a,10b) with a clutch and tank pipe (11,12), between the piston chamber (8) and the spring chamber (9) of the regulator valve. A second choke (14) adjustable to the closing time of the clutch (K) is inserted into the outlet pipe (13) leaving the end part of the spring chamber to the return (4). A relief outlet (15) is connected to the return and leaves the spring chamber at a point apart from its outlet pipe.
