Abstract:
A control valve (4) for controlling pressure medium flows of a camshaft adjuster, which control valve includes a substantially hollow cylindrical control sleeve (6), which is disposed inside a casing (8), and a control piston (12) which is guided axially displaceably inside the control sleeve (6) against the spring force of a spring element (14), the control sleeve (6) having at one axial end a base (22) which serves as an axial contact surface for the spring element (14).
