MUELLE DE COMPRESION DE LONGITUD AJUSTABLE ASI COMO ASIENTO CON UN MUELLE DE COMPRESION DE ESTE TIPO.

摘要

A piston (12) attached to a piston rod (8) can be axially moved inside a housing (1) dividing the inner space into two pressure chambers (15, 16) connected when a first valve (20) is opened. The spring is locked when the valve (20) is closed. An additional throttle valve (36) facilitates an overflow connection to fully open only when the throttle element (36) is moved into a release position. An uncontrolled moving of the piston rod (12) is prevented.
