Hydraulisches Ventil, insbesondere zur Steuerung einer Nockenwellenverstellung in einem Kraftfahrzeug

摘要

The invention relates to a hydraulic valve, especially for controlling a camshaft movement in an automobile. The inventive hydraulic valve has a valve bush (13) which can be inserted with one front end (39) first into a receiving bore (12) of a housing (10), and an axial control bore (31) into which a disc (40) can be inserted from the front end (39). The aim of the invention is to reduce the cost and complexity of producing the individual parts and assembling the valve. To this end, the disc (40) is pressed into the control bore (31) so that it has a press fit, and the valve bush (13) is provided with a turned groove (45) on the outside from the front end (39), to one side of a lubricant flow. Said turned groove (45) prevents the outer surface of the valve bush (13) from becoming too large as a result of expanding when the disc (40) is pressed in.
