Thermostatic valve having a sleeve

A thermostatic valve, including:

• a housing in which a fluid circulates,
• a sleeve for regulating the circulation of the fluid in the housing, this sleeve being substantially centered on an axis along which the sleeve is movable relative to the housing to cut/allow a flow of fluid,
• a thermostatic element, containing a heat-expandable material and comprising a stationary part, which is fixedly connected to the housing, and a moving part, which is movable along the axis relative to the stationary part resulting from an expansion of the heat-expandable material and which bears the sleeve to cut/allow the flow of fluid,
• a compression spring for returning the stationary part and the moving part of the thermostatic element toward one another, and a bracket for supporting the compression spring, which, during use, supports a decompression thrust produced by the compression spring and which is provided with:
• fasteners for fastening to a bearing portion of the housing that is transverse to the axis, said fasteners cooperating in a form-fitting manner with the bearing portion so as to be attached with the bearing portion along the axis resulting from a decompression thrust produced by the spring, and
• locking features that axially abut against the bearing portion of the housing so as to keep the fasteners attached to the bearing portion when a stress compressing the compression spring is applied on the bracket.
