ABSTRACT:
An enclosed space which constitutes part of an operating chamber of a cylinder is left between a piston and the bottom of the cylinder or between a piston and another piston when the piston is brought into contact with the bottom or the other piston. At least one groove or recess is formed in either the piston or the bottom, or in either the piston or the other piston so that communication between the enclosed space and a fluid port of the cylinder is not blocked even when the piston is brought into contact with the bottom or the other piston.
