Hydraulic control valve e.g. proportional control valve, for controlling hydraulic camshaft adjuster in internal combustion engine, has transmission element pivotably supported at side surfaces of control pistons and control elements

摘要

The valve has a control unit comprising a sliding control element (18). A transmission element (17) has two side surfaces (36, 37) lying at a side surface (34) of a control piston (13) and a side surface (35) of the control element, respectively. The side surfaces of the transmission element, control pistons and the control elements are formed in a touch region in a concave and convex manner. The transmission element is pivotably supported at the side surfaces of the control pistons and the control elements.
