Abstract

This element (101) comprises a cup (110) containing a thermally expanding material (120), a piston (130) capable of translational movement along its axis (X -X), a rigid guide (140) for guiding the translational movement of the piston , a seal (150) for sealing in the thermally expanding material having an annular overall shape, centred on the axis and through which the piston passes axially right through, and which includes first (152) and second (153) opposite axial parts against which the guide and the cup press respectively in a substantially antagonistic manner so as to compress the seal around the piston and an anti -extrusion washer (160) mounted coaxially around the piston and axially interposed between the guide and the first part of the seal. The invention provides for including in this thermostatic element means (144) for supercompressing the first part of the seal around the piston which means are designed to make the degree of compression of the first part of the seal equal to a value strictly higher than that associated with an operational thermostatic element formed by the cup , the piston , the guide , the seal and the anti- extrusion washer assembled with one another without these supercompression means.
