摘要：The device (1) has a mechanical spring (3) and a gas spring (4) that is controlled at a given engine rpm range, which are connected in parallel to close the gas shuttle
valve (2). The gas spring has a piston (6) that moves to close a chamber (5). The gas spring
piston is formed as a rammer (7) with a piston shroud (9) sealingly sliding in the chamber to separate it from the gas spring chamber. The gas spring is supplied from the pump space, which is controlled by a medium, over a controlled overflow channel (10) for the compressed medium during the maximum opening stroke of the gas shuttle valve.
