The inventive thermostatic element comprises a cup (1) containing a material (3) which is expendable and contractile according to the direction of the temperature variation thereof and a piston (5) which is movable with respect to the cup in the axial direction (X-X) thereof and is coupled to the expendable and contractile material in such a way that it is displaceable in the opposite direction according to the material expansion or contraction. In order to reduce the element response time in a simple and reliable manner, the cup (1) is embodied in one metal piece which internally delimits at least two distinct internal cavities (14A) for receiving at least one part of the expendable and contractile material (3).
A thermostatic element, comprising a cup (1) containing a material (3) that can expand and contract depending on the direction of variation of its temperature, and a piston (5) that can move relative to the cup in an axial direction (X-X) of the latter and that is coupled to the expandable and contractile material in order to move in opposite directions depending on whether the material expands or contracts, characterized in that the cup (1) is made in a single metal piece that internally delimits at least two distinct internal cavities (14A;
The thermostatic element as claimed in claimed, characterized in that the cup (1) is furnished with external ribs (16) protruding outward.
