CONTROL VALVE FOR A CAMSHAFT ADJUSTER

摘要

A control valve (4) for controlling pressure medium flows of a camshaft adjuster which includes a substantially hollow cylindrical valve housing (6), a control piston (12), which is guided axially displaceably inside the valve housing (6), and a non-return valve (22) which can be hydraulically released. In a region of a pressure medium inlet, the valve housing (6) includes a housing shaft (28) with an axial inflow bore (30) which widens in funnel-like manner towards the inlet side.
