Patent ID: 8550371

Claim:
A thermostatic fluid flow regulating assembly, comprising: a flow obstructing sleeve having a center on a longitudinal axis and first and second ends, a seat, across which a fluid flow passes and which defines a bearing surface for the first end of the sleeve, the bearing surface extending in a plane approximately perpendicular to the longitudinal axis, and the first end of the sleeve defining a housing which is, in a radial direction relative to the longitudinal axis, both closed by a lateral wall that is integral with a tubular body of the sleeve and open opposite the lateral wall, and which is, in a direction parallel to the longitudinal axis, both open towards the bearing surface and closed opposite the bearing surface by an end wall that is integral with the tubular body of the sleeve, a thermostatic element which includes a heat-sensitive part which is across the fluid flow and which contains a thermally expansive material and a movable part which moves in translation relative to the heat-sensitive part in a direction parallel to the longitudinal axis in response to a variation in a volume of the thermally expansive material, the sleeve being connected to one of the heat-sensitive part and the movable part of the thermostatic element and the seat being connected to the other of the heat-sensitive part and the movable part of the thermostatic element, in such a way that the relative movements of the heat-sensitive part and the movable part along the longitudinal axis control the flow of fluid radially to the longitudinal axis through a passage formed axially between the first end of the sleeve and the bearing surface, and a flexibly deformable gasket which is secured within the housing by a ring having both a first wall interposed axially between the end wall and the gasket and a second wall, the gasket being radially interposed between the second wall of the ring and the lateral wall of the sleeve such that a portion of the gasket extends outwardly of the housing toward the bearing surface, at least one of the lateral wall of the sleeve and the second wall of the ring being bent toward the other of the lateral wall and the second wall to crush the gasket.
