Claims

[Scope of Claim for Utility Model Registration] The valve body of the control valve is fixedly fitted into the valve storage chamber formed in the cylinder body or piston rod, and within this valve body there is an operating piston chamber and an operating piston chamber. A continuous control piston chamber is formed on both sides, an operating piston is slidably fitted into the operating piston chamber, and a control piston is slidably fitted into the control piston chamber. The control piston on the sliding direction side is associated with the valve body so as to be pressed and moved by sliding in one direction, and the valve body is configured such that both side portions of the operating piston chamber are communicated with the pressure fluid supply passage of the cylinder body or the piston rod. A supply hole is formed in the control piston chamber, and a discharge hole is formed so that a portion of the control piston chamber opposite to the operation piston side communicates with both side portions of the piston chamber, and the control piston further includes a valve hole smaller than the discharge hole. When the control piston is slid to the side opposite to the operating piston side, this control piston
. A double-acting cylinder with a control valve, in which both sides of the cylinder are formed to communicate with each other, but to cut off communication when slid toward the operating piston.
