Patent ID: 7520446

Claim:
A thermostatic valve for a fluid circuit, including: a housing having at least one fluid circulation path therein, a blocking valve means for opening and closing the circulation path, a thermostatic element including a body containing an expansible material and a piston engaging the body such that the body and piston are movable relative to one another under action of the heat expansible material, the body being disposed in the fluid circulation path and carrying the blocking valve means, and the piston being immobilized with respect to the housing, electrical heating means for heating the expansible material, the electrical heating means being disposed, at least partially, within the piston of the thermostatic element, connection means for forming an electrical connection between an outside of the housing and the heating means including at least one electrical contact pin accessible from outside the housing, a connection base for connection of an element for supplying electric power to the at least one electrical contact pin, electrical conductors which connect the at least one electrical contact pin to the heating means, and a support base for the conductors and for the at least one electrical contact pin which is firmly connected to the housing, and wherein the support base is immobilized in a substantially complementary blind cavity formed internally of and integrally with the housing, and wherein a bottom of the cavity includes a wall which is traversed by the at least one electrical contact pin and a sealing gasket being interposed between the wall and the support base.
