Claims

[Scope of utility model registration request]

A diaphragm to which the rond is fixed defines two chambers in the case, and one of the two chambers is communicated with a pressure source or a negative pressure source to create a pressure difference between the two chambers to cause the rond to be fixed. In a differential pressure actuator that displaces,
a housing that is combined with the case to define a switching chamber;
a first passage formed in the case and communicating between one of the chambers and the switching chamber; a second passage communicating between the pressure source or negative pressure source and the switching chamber; and opening the switching chamber to the atmosphere. a valve body that is movably housed in the switching chamber and selectively closes the communication passage or the second passage;
a pressure rod that is integrally provided with the rond and movably protrudes into the switching chamber and engages with the valve body; a spring that urges the valve body in the direction of the pressure rod; and a spring that biases the valve body in the direction of the pressure rod; A differential pressure actuator comprising: a solenoid that communicates one of the pressure source or negative pressure source with the pressure source or the negative pressure source, or opens it to the atmosphere.
