<p>A pressure responsive actuator mechanism consists of a housing and a diaphragm dividing the interior of the housing into first and second chambers. An actuator support is located in the first chamber and is carried by the diaphragm. An actuator is fixed at one end to this support to extend therefrom through one end of the housing to the exterior thereof. The actuator support and the diaphragm are biased towards the opposite end of the housing. A fluid is admitted at a pressure that may vary into the second chamber to impose on the diaphragm a force opposing the biasing force. As the fluid pressure varies, the actuator will be shifted in position relative to the housing.</p> |
