<p>PURPOSE: To provide a cylinder controlling circuit which facilitates the set or change of a cylinder output in a stroke in the same direction despite the small number of part items and simpleness in structure. CONSTITUTION: A controlling circuit C1 for a cylinder 5 is provided with a first main pipe line 17, which connects a cylinder room R1 on one side and a fluid supplying source, and a second main pipe line 18, which connects a cylinder room R2 on the other side and the fluid supplying source. A piston 14 within a cylinder main body 12 makes reciprocal motion, owing to the action of the fluid pressure supplied through these main pipe lines 17, 18. A bypass pipe 32 is prepared between both cylinder rooms R1 and R2. A two-position, two-port type solenoid valve 33 as a directional control valve switches the bypass pipe 32 into a communicated state or into a non-communicated state. A throttle valve 36 as a flow rate adjusting valve regulates the flow of the fluid within the pipe.</p> |
