クチユエータ。 a cylindrical casing having an opening at one end; a diaphragm installed inside the cylindrical casing to define a positive pressure chamber into which positive pressure is introduced;
an auxiliary diaphragm that is fixed to the cylindrical casing so as to cover the opening and define a negative pressure chamber into which negative pressure is introduced to the back of the diaphragm; and an auxiliary diaphragm that biases the diaphragm in a direction that reduces the volume of the positive pressure chamber. a return spring; and an actuating rod having one end connected to the diaphragm, the other end of the actuating rod penetrating the negative pressure chamber and projecting to the outside of the negative pressure chamber, and a gap formed in the penetrating portion of the actuating rod. The negative pressure chamber is communicated with the atmosphere through the negative pressure chamber, and a seat is provided in the penetrating portion of the negative pressure chamber, and a valve body is provided on the actuating rod to seat on the seat and seal the gap. Diaphragm actuator.
