Claims

[Claims for Utility Model Registration] 1. A diaphragm whose outer periphery is sandwiched in a sealed state by a casing body and a lid body, on one side of the central part thereof, is connected to a covered control element through a through hole in the casing body. A fixed plate-shaped body is fixed, and the operation is activated by the pressure of the operating fluid supplied from the supply port opened in the lid to the space between the lid and the diaphragm. In a diaphragm type actuator, the diaphragm is made up of two diaphragms, one on the operating shaft side and one on the lid side, and pressure regulating fluid is supplied to the space between the two diaphragms, and the fluid in the space is A diaphragm actuator characterized by being equipped with a detection device for detecting pressure. The diaphragm actuator according to claim 1, wherein the 22 diaphragms are the same. 3. The tire flam actuator according to claim 1 or 2, which uses the same type of operating fluid and pressure regulating fluid. 4. The diaphragm actuator according to any one of claims 1 to 3, which uses a pressure regulating fluid with a constant pressure lower than the pressure of the operating fluid as the pressure regulating fluid. 5. The diaphragm actuator according to claim 4, wherein the detection device is activated when the pressure of the operating fluid reaches the lowest pressure. 6. The diaphragm type % type % according to claim 4 or 5 of the utility model registration claim, in which the detection device is activated when the pressure reaches below the regulated pressure of the pressure regulating fluid.
