Abstract

A thermostat control device (1) comprises a housing (2) within which there is provided a diaphragm (4) and temperature sensor (5) coupled via a capillary system (6). A drive screw (12) is threadingly engaged to a correspondingly threaded diaphragm head (7) which moves the drive screw (12) in response to temperature changes at the sensor, bringing a striker arrangement (15) into and out of engagement with a moveable contact (18) to "break" and "make" electrical connection with a fixed contact (19). A rotatable user control spindle (30) receives a tabbed end (25) of the drive screw (12) within a receiving slot (27) allowing rotation of the drive screw with respect to the diaphragm (4) without imparting axial movement to the user control spindle (30). A diaphragm actuator for use in regulators and thermostatically controlled devices is also disclosed. Calibration of the device is achieved by adjusting the depth of engagement between the drive screw (12) and the diaphragm head (7), thereby eliminating the need for a conventional calibration screw mechanism.
