Gas spring

The gas spring has a cylinder (1) containing a working chamber (1a), closed at one end by a compensating piston (10) extending outside it, and inside by a working piston (2). The cylinder is surrounded by a compensating medium (16M) which expands with temperature change and has a critical temperatur...

Zusammenfassung:The gas spring has a cylinder (1) containing a working chamber (1a), closed at one end by a compensating piston (10) extending outside it, and inside by a working piston (2). The cylinder is surrounded by a compensating medium (16M) which expands with temperature change and has a critical temperature between the upper and lower operating temperature thresholds for the spring. The dimensions of the spring components are chosen so that the state of the compensating medium when the spring operates is on or above the vapor pressure curve.
