Embodiment Construction

[0014] figure 1 and 2 A valve 1 is shown, which is suitable for regulating the circulation of a fluid after passing through a regulating chamber 13 , which enters the housing 10 through an opening 11 and exits the housing through an opening 12 which opens into the regulating chamber 13 . In the regulating chamber 13 there are arranged a movable sleeve 20, a fixed seat element 30 and a thermostatic part 40 which controls the movement of the sleeve relative to the seat element. The valve 1 is used, for example, in the cooling circuit of a motor vehicle heat engine.

[0015] The overall shape of sleeve 20 is tubular, with figure 1 and 2 The cutting plane passes through the longitudinal axis X-X as the center. This sleeve is located in a regulating chamber 13 such that the opening 11 opens into it substantially perpendicularly to the axis X-X, while in the embodiment here the opening 12 is substantially centered on this axis.

[0016] The sleeve 20 comprises a cylindrical bod...

Abstract

The invention relates to a valve (1) which comprises a housing (10) defining fluid inlet and outlet openings (11, 12), as well as a sleeve (20) for controlling the circulation of said fluid through the housing, the movement of said sleeve along the axis (X-X) thereof being controlled by a thermostatic element (40). In order to increase the maximum flow of fluid said valve can take in, the valve also comprises a seat part (30), which is fixedly mounted on the housing (10) and which includes a fluid-tight wall (31), one of the two opposite surfaces thereof extending transversely to the axis (X-X) of the sleeve (20) to define a seat (32) for bearing the sleeve (20) while the other one of said two opposite surfaces defines, between the latter and a wall of the housing (1) in the direction of the axis (X-X) of the sleeve, a free space (V) into which one (11) of the openings (11, 12) leads and through which the fluid flows, being distributed over the entire periphery of the sleeve when said sleeve is in the open position thereof.

Description

technical field [0001] The invention relates to a thermostatic valve for a fluid circuit, in particular a cooling fluid of a heat engine. Background technique [0002] Cooling circuits associated with heat engines of large working volume, especially those used in trucks and some automobiles, are usually equipped with valves with regulating sleeves whose movement is controlled by a thermostatic part, for these heat engines, the required The flow rate of the cooling fluid is higher than that of the heat engine with a small displacement. For the heat engine with a small displacement, the thermostatic valve used is a valve type. [0003] In fact, the use of the sleeve makes it possible to place a balanced plug, ie a substantially zero pressure difference on both sides of the sleeve wall along the direction of movement of the sleeve moved by the thermostatic part, which direction practically corresponds to the axial direction. On the contrary, in valve-type thermostatic valves,...
