Claims

[Scope of utility model registration request]

A release cylinder chamber to which pilot fluid is supplied, a release piston fitted in the cylinder chamber so as to be slidable in the axial direction, and an air cylinder chamber disposed on the axial extension of the release cylinder chamber. and an air piston that is slidably fitted into the cylinder chamber and connected to the release piston, and one end of the rod is arranged concentrically with the air piston and the release piston, which is connected to the actuated device. and a first valve chamber that communicates with the air cylinder chamber on the opposite side of the air piston rod and the outside air, respectively, and is slidably fitted into the first valve chamber,
a first valve body configured to move in response to fluid pressure supplied to the release cylinder chamber; and a first valve body configured to allow both chambers of the first valve chamber to communicate with each other. A first valve passage and a second valve passage opened concentrically with the air piston.
a valve chamber, an air supply pipe connected to supply compressed air to the second valve chamber and extendably accommodated in the air cylinder chamber; an air supply pipe in the second valve chamber; and the first air supply pipe. a second valve passage formed between the valve chamber; and a second valve passage disposed in the second valve chamber that corresponds to movement of the first valve body to
A booster comprising a second valve body configured to open and close a valve passage.
