Claims

[Scope of utility model registration request]

The pressure chamber formed by the piston that is slidably fitted into the bore in the mask cylinder body and the inside of the reservoir,
A check valve that allows the working fluid to flow from the inside of the reservoir to the pressure chamber when the pressure in the pressure chamber becomes negative with respect to the pressure inside the reservoir; When the pressure is positive, the pressure chamber communicates with the reservoir through a relief valve that allows the flow of working fluid from the pressure chamber into the reservoir, and further, the relief valve is arranged in the hollow part of the main body of the check valve and is connected to the seat part. A mask cylinder device comprising a valve body made of an elastic material and having an annular protrusion on which it is seated.
