Problems solved by technology

However, such an arrangement can lead to failure of the valve when, especially in the case of mishandling or shocks during installation or maintenance of the valve, considerable stress is exerted on the bracket and causes compression of the spring: the risk is that the bracket will partially or completely Separated from the supporting part of the housing

Embodiment Construction

[0013] figure 1 to 5 show a valve 1 suitable for controlling the circulation of a fluid. For example, valve 1 is used in the cooling circuit of a heat engine of a vehicle.

[0014] The valve 1 comprises a housing 10 in which the fluid mentioned above circulates. The housing 10 is in particular made of plastic, for example by moulding. In the example considered here, as figure 1 and 2 As clearly shown, the housing 10 comprises a main body 11 comprising a closed wall 12 separating the inside and the outside of the main body 11, the fluid regulated by the valve only in the Medial flow. Such as figure 1 Clearly shown, the closure wall 12 extends transversely to the geometrical axis X-X, which belongs to figure 1 , and for convenience the rest of the description is adjusted with respect to the geometric axis X-X, which is considered to extend along the vertical inner side of the main body 11, which is the inner side of the closed wall 12 in figure 1 To the side turned up in...

Abstract

The invention relates to a thermostatic valve (1), comprising: a housing (10); a sleeve (20) for controlling the flow of the fluid in the housing, which is movable along the axis (X-X) thereof; a thermostatic element (30), the movable portion (31) of which is movable along the axis relative to the stationary portion (32) thereof as a result of the heat-expansible material of said element expanding so as to move the sleeve; a compression spring (40) for returning the stationary and movable portions towards one another; and a bearing collar (60) for the spring which, during operation, bears the decompression force produced by the spring and which is provided with means (66) for attaching to a bearing surface (13) of the housing that is transverse to the axis, said attachment means engaging with the bearing surface in a form-fitting manner so as to be hooked onto the bearing surface along the axis due to the decompression force produced by the spring, as well as with means (67) for locking the collar in position while axially abutting the bearing surface so as to retain the attachment means hooked onto the bearing surface when a load (F) for compressing the spring is applied onto the collar.

Description

technical field [0001] The invention relates to a thermostatic valve, in particular a thermostatic valve for a fluid circulation circuit, in particular a thermostatic valve for the coolant of a heat engine. Background technique [0002] The valve is provided with a regulating sleeve for the circulation of the fluid, the movement of which is controlled by a thermostatic element usually equipped for those associated with large displacement heat engines, especially those used in trucks or certain motor vehicles Cooling circuits in which large displacement heat engines require higher coolant flow rates to operate than would be encountered with heat engines of smaller displacement using thermostatic valves typically with gates. [0003] In fact, the use of a sleeve often makes it possible to have a so-called balanced shutter, ie a shutter for which there is generally a The difference in pressure is substantially zero, and this direction actually corresponds to the axial directio...
