Gas compression cylinder as nitrogen spring has control element in cylinder to control force flow by producing or release connection between upper and lower chambers as cylinder moves from position on lid towards base

摘要

The force flow is controlled through a control element mounted in the cylinder (Z) so that when the piston is moved from a position on the lid (1c) towards the base (1a) a connection is produced between the lower chamber (3) and the upper chamber (4) and the force flow is reduced or kept constant or the connection between the two chambers is interrupted and the force flow is then increased. The control element is formed by a control rod (5) which engages in one of the bores in the piston.
