Abstract

The actuator has an auxiliary piston (ZK) and a main piston (HK) held apart by a spring (F). Pressurised oil gains access through a restrictor bore (B) in the auxiliary valve to the main piston to open the valve. On the closing stroke the oil is rapidly ejected through the feed pipe (L) until a stop (A) on the auxiliary valve reaches the cylinder and the main cylinder continues to move over the distance (As) forcing the oil at a slower rate through the restrictor
