CONTROL VALVE FOR A CAMSHAFT ADJUSTER SYSTEM

摘要

A control valve for a hydraulic device, in particular central valve of a camshaft adjuster system for reciprocating-piston internal combustion engines, having a valve sleeve (1) which projects into a cavity of a camshaft (8), wherein a displaceable control piston (3) is arranged in the valve sleeve (1), which control piston is subjected to load on one side by a spring (4) which is adjoined by a pressure medium line. The cavity of the camshaft (8) is connected to a pressure medium supply channel of the reciprocating-piston internal combustion engine via at least one supply line (16) in the camshaft (8) and via a bearing, and the pressure medium line is in the form of a pressure medium feed line and the pressure medium feed line is connected to the pressure medium supply channel of the reciprocating-piston internal combustion engine via a pressure line (12) in the camshaft (8) and via the bearing.
