Claims

[Scope of utility model registration request]

A piston boss 13 is formed above the valve body 11, and a piston 14 is mounted therein so as to be movable up and down.
A piston working fluid intake port 16 is formed in the valve body 11 portion in communication with the piston boss 13, and the valve body 1
A switching fluid intake port 21 and an intake-side fluid passage 22 continuous to the intake port are formed below the switching fluid intake port 1, and a switching fluid outlet 23 and a delivery-side fluid passage 24 continuous to the delivery port are formed below the switching fluid intake port 21.
A valve chamber 25 is formed above both fluid passages 22, 24, an upper edge 27a of a bellows valve 27 is fixed above the valve chamber 25, and a piston rond 28 whose upper portion is fixed to the piston 14. In the switching valve formed by fixing the lower part to the bellows valve 27,
Bellows valve 2 provided in valve chamber 25-
A compressed air passage 29 is provided with an opening at one end positioned such that compressed air can be fed into the valve body 7, and an opening 30 at the other end of the passage is opened on the outer surface of the valve body 11 to form a compressed air intake port. A structure characterized by having formed.
