Claims

[Scope of utility model registration request]

A double-acting, single-rod cylinder in which a piston rod extending from a piston in a cylinder tube in one direction in the axial direction projects outward through a head cover at one end of the cylinder tube, and the piston rod extends outward from a piston rod at one end of the cylinder tube. A pipe connector is provided, and a first port that communicates one of the two pipe lines of the double pipe connected to the connector with the first pressure chamber between the end cover and the piston, and a first port that communicates the other pipe line with the first pressure chamber between the end cover and the piston. a second port connected to a fluid passage leading to a second pressure chamber between the piston and the head cover, the end cover having a first port interposed in the first port;
A double-acting, single-rod cylinder comprising a speed regulating valve and a second speed regulating valve interposed in the second port.
