Claims

[Scope of utility model registration request]

The inside of the housing formed by the lower body, intermediate body, and upper body is divided into a first chamber, a second chamber, and a third chamber by two diaphragms, and the first chamber is always connected to the atmosphere, and the airtight second and third chambers are Each chamber is equipped with a tap that connects to atmospheric pressure and negative pressure, and the fixed cylinder attached to the center of the lower body has a stepped part that is biased upward from below and engages with the lower surface of the fixed cylinder. A movable cylindrical body that engages with a stepped portion provided at the intermediate portion of the output shaft is fixed to the lower diaphragm by penetrating the lower diaphragm. A negative pressure actuator characterized in that the actuating distance is longer than that of item 2.
