ABSTRACT:
A cylinder with a speed control mechanism wherein in a transfer stroke, a piston is smoothly accelerated or smoothly decelerated at an initiation or termination end of the stroke by controlling the speed of the piston, whereas in a return stroke, the speed of the piston is not controlled, thereby reducing the time required for the return stroke. A bypass passage bypassing longitudinal grooves for flow control provided on a cushion ring (74) is formed in a passage which provides communication between the outside and a main passage or a cylinder chamber (71, 72). A check valve (78A, 78B) is disposed in the bypass passage to allow a fluid to flow through the bypass passage only during the return stroke of the piston (6).
