ロツトエア切換装置。[Scope of Claim for Utility Model Registration] (1) A pair of left and right control chambers that have diaphragms that are displaced according to the magnitude of introduced pressure; a high pressure port and a low pressure port that communicate with the left and right control chambers, respectively;
A pair of left and right diaphragms are integrally provided in the center of the pair of diaphragms, and selectively connect the regular port to either the high pressure port or the low pressure port, depending on the movement position caused by the displacement of the diaphragms. a valve body; and selectively moving pressing means that presses and displaces the other valve body in a direction that communicates the low pressure port with the common port when one of the pair of left and right valve bodies is displaced in the direction of communicating the common port with the high pressure port. and further, when the valve body communicates the normal port with the high pressure port, the pressure receiving area of the diaphragm from the high pressure port is greater than the pressure receiving area when the valve body communicates the normal port with the low pressure port. A self-sealing type air pilot switching device characterized by a large setting. (2) In paragraph 1 of the claims for utility model registration,
The alternative pressing interlocking means has a rotation fulcrum in the intermediate portion,
This is a self-sealing type pilot air switching device in which the swing arm has both ends abutting against the heads of the left and right valve bodies, and an actuator that provides an initial swing force is connected to this swing arm.
