摘要

The pneumatic starting valve has rapid venting (1) for a path valve and has two connecting channels (6,7) together with a rapid venting channel (5). It is connected to a baseplate (4) and in its housing block a movable piston (8) with a displaceable seat valve (9) is arranged. In its chamber at different points the three connecting channels issue. The piston in two opposing end positions and a central position frees the passage between two connections. Via an air feed throttle check valve (10) and control air connection (16) the piston is connected with the check valve (13) via a channel (12).
