This device (2) comprises a thermostatic element (10); a main seal (20), that can be moved axially relative to a fixed seat so as to open and close a main valve and that is linked to the movable part (12) of the thermostatic element to open the main valve, the main seal and the thermostatic element being assembled together, forming a first module (M1); a spring (50), that biases the movable part towards the fixed part of the thermostatic element to control the closing of the main valve; a bracket (40) for supporting the spring, that is interposed axially between the spring and a fixed casing; and a support cradle (30) for supporting the first module, that is suitable for removably inserting the first module therein, by axially interposing the cradle between the first module and the spring, that includes a by-pass seal (36), that is axially movable relative to a fixed seat of the bracket so as to open/close a by-pass valve when the main valve is opened/closed, and that is linked to the bracket in an axially movable manner, with the spring interposed axially, while being held fixedly to the bracket in such a way as to keep the spring in the compressed state between them. The spring, the bracket and the cradle are assembled together separately from the first module, forming a second module (M2) separate from the first module. |
