Process for manufacturing a thermostat, and thermostat obtained.

摘要

The control shaft (4) screws into and unscrews from a boss (13) of the body (1) so as to press on the capsule (8) during calibration. The control knob is forced to rotate with the shaft (4) because of a flattening made on the shaft (4) in the calibration position. This enables a protective spring (16) to be inserted between the shaft (4) and the capsule (8), thus allowing expansion due to any accidental or foreseeable overheating or to the withdrawal of the knob. <IMAGE>
