ABSTRACT:
A piston and cylinder assembly having a cylinder with a piston and a connected piston rod. The piston defines opposed chambers wherein a compensating device is disposed in at least one of the chambers. The compensating device includes a capsule of an elastic material containing a gaseous medium which is compressed comparable to the volume displaced by the piston rod when fully retracted. When the piston rod is in its protracted position, the compensating capsule expands so that the pressure within the hydraulic chamber of the cylinder reaches a value that will minimize the absorption of any air into the cylinder and not overload the bearing seal through which the piston rod extends.
