Claims

[Scope of utility model registration request]

(1) A cylinder main body, a drive shaft holding a piston that reciprocates within the cylinder main body, a container fixed relatively to the cylinder main body, and a pair of cylinders installed in the container. limit switches; an actuating member rotatably mounted in the container so as to alternately actuate these limit switches; and the actuating member is reciprocally rotated in response to the reciprocating movement of the drive shaft. a solenoid valve attached to the container so as to alternately switch the fluid entering the cylinder body from one side of the piston to the opposite side of the piston; The electromagnetic valve is actuated by the pair of limit switches, and when the limit switches are actuated alternately, the solenoid valve alternately switches the flow path of the fluid entering the cylinder body, and controls the piston and the drive shaft. A control unit for hydraulic and pneumatic cylinders that is characterized by reciprocating motion.

(2) A control unit for a hydraulic/pneumatic cylinder according to claim 1, wherein the connection position between the drive shaft and the connecting arm is adjustable so that the stroke of the drive shaft can be changed. .

(3) A control unit for a hydraulic/pneumatic cylinder according to claim 1 or 2, wherein the container is sealed to be watertight or explosion-proof.
