PNEUMATIC DECELERATION DEVICE HAVING CONSTANT POWER

摘要

The invention relates to a pneumatic deceleration device having a cylinder and having a piston which is guided in said cylinder by means of a piston rod, is equipped with at least one piston sealing element and delimits a displacement chamber with respect to a compensation chamber. The pneumatic deceleration device according to the invention builds up a force by creating an overpressure in the displacement chamber and a negative pressure in the compensation chamber, said force opposing the reciprocating movement of the piston, wherein the leakage flow between the displacement chamber and the compensation chamber is at least dependent on the reciprocating direction. The deceleration device comprises a closable pneumatic connection in the final position of the piston of the maximum displacement space so that the displacement chamber and the compensation chamber communicate with the surroundings in this final position of the piston. The present invention thus provides a pneumatic deceleration device that has a low dispersion of deceleration forces.
