<p>A condition responsive control device (10) comprising a case (12), a controller (14) carried by the case, a linkage system (16) supported by the case and coupled to the controller, and a condition responsive linkage actuator (20). The actuator comprises a convoluted bellows (46) having an anchor convolution hermetically fixed to a bellows supporting housing (30). An anchor convolution mounting face and a housing bellows support zone are bonded together to secure the bellows to the support housing so that the bellows operates the linkage and controller in response to pressure differentials. <IMAGE></p> |
