<p>The start valve has a piston (7) whose two pressure surfaces (7a,7b) have a displacement effect in the direction of the open position. The first and second pressure surfaces are the same size. A throttle opening (9) is formed between the end region of the piston (7c) and a wall (2a) of the channel (6) in order to maintain a small pressure medium flow. The size of the throttle opening during the closed position of the piston can be altered by an adjustment screw (11).</p> |
