| 摘要 |
A control valve for a cam shaft adjuster, including a valve housing and a control piston, which is designed as an injection-molded product and is axially displaceably mounted within the valve housing and which has a substantially tubular main body, wherein the control piston, on an end face, has an actuating surface for a control component. To this end, the control piston includes, at an end thereof, an axially extending molded-on component which includes a gate point on one of the lateral faces thereof. Such a design of a control valve allows the control piston to be securely guided within the valve housing at low manufacturing cost of the control piston.
