FIELD: machine building. ^ SUBSTANCE: proposed mechanism comprises pilot stage made up of electrohydraulic proportioning valve electrically connected to control unit, main stage made up of three-line restricting slide multiposition hydraulic control valve and element indicating filling of throw-in friction-clutch hydraulic cylinder. Main stage and pilot stage attached to main valve body joint surface are integrated in single unit. Said indicator is structurally separated from main stage. Main stage body hydraulic chambers are arranged on the side of its joint to controlled structure and geometrically defined by combination of planes and cylindrical surfaces. Said chambers are produced by machining to feature box shape. Aforesaid indicator is made up of one or several elements, i.e. pressure gage, working fluid flow valve, or flow rate meter, friction-clutch drive and drive part rpm transducers. ^ EFFECT: higher reliability. ^ 7 cl, 9 dwg |
