Abstract

PURPOSE: To allow various sorts of configuration of the main unit by absorbing the oil chamber space reduction by an elastic substance as well as to return a piston to the initial position with the aid of springy action of the substance by putting a considerably expensible and confractable elastic substance into an oil chamber at the cylinder rod side.
CONSTITUTION: Many considerably expansible and contractable elastic substances 28 are contained in a chamber No.2 20 together with working oil. The movement of a piston 14 by compressed oil compresses the working oil in the chamber No.2 20. The elastic substances 28 shrink according to the pressure, absorbing the reduction in volume of the chamber No.2 20. With the suspension of compression to a chamber 24, the elastic substances start expanding, increasing the volume of the chamber No.2 20, whereby the piston 14 is returned to the initial position.
