Device for a valve system, comprising: a housing with a seat for being coupled to a base and exchanging water streams when the housing is in a first coupling position, the seat comprising a first seat opening fluidly connecting to a first base opening when the housing is in the first coupling position; an adjuster which is contained inside the housing for adjusting the flow rate of one of the water streams; and a controller for controlling the adjuster. To avoid any complications in the event of an error while making the system more versatile, the seat comprises a breakable portion which can be broken off from the seat to enable it to be coupled in a second coupling position, the first seat opening subsequently fluidly connecting to a second base opening.

The instrumented device comprises a body to be attached to a mixing valve producing a mixed fluid by blending hot and cold fluids. The body defines a main channel and a bypass channel, provided for the outflow of the mixed fluid through the body. The device comprises a turbine arranged in the main channel, being bypassed by the bypass channel, such that, as soon as the flow rate of the mixed fluid flowing through the body is non-zero, all or a portion of the mixed fluid flowing through the body passes through the main channel passing through the turbine and, at the same time, a portion of the mixed fluid flowing through the body is likely to bypass the turbine by flowing in the bypass channel between the upstream and the downstream of the turbine.

A thermostatic cartridge includes: a casing at least partially within and locked translationally along an axis a cartridge body that delimits a chamber, a hot and cold fluid inlet passages and a mixed fluid outlet passage; a slide valve regulating the temperature of the mixed fluid displaceable along the axis to close, in inverse proportions, the inlet passages; a thermostatic element; and a mechanism for adjusting a thermostatic regulation temperature mechanically and displaceably connected to the body and to secure the position of the piston of the element along the axis and to alter the piston position by actuating the adjustment mechanism to move relative to the body. To control the regulation temperature, the casing is rotationally mounted on the body such that the adjustment mechanism is actuated when the casing is between positions-corresponding to extreme low and high temperature values.

The cartridge comprises a slide valve for regulating the temperature of a mixture of hot and cold fluids. The slide valve is, under the action of a thermostatic element and in relation to an outer casing of the cartridge, which can be displaced along the central axis of the casing in such a way as to vary inversely the respective flow sections of an inlet for a first of the fluids, delimited axially between the casing and one of the two opposite axial surfaces of the slide valve, and of an inlet for the second fluid, delimited axially between the casing and the other axial surface of the slide valve. Therefore the cartridge can, effectively and economically, provide a good mixture of the two fluids, a flow passage.

A valve includes a housing which defines openings for the inlet and outlet of a fluid. The valve also includes a sleeve for controlling the circulation of the fluid through the housing. The movement of the sleeve along its axis is controlled by a thermostatic element. In order to improve the maximum flow of fluid that the valve can take in, the valve further includes a seat part, which is fixedly mounted in the housing and which includes a fluid-tight wall. One of the two opposite surfaces of the wall extends transversally to the axis of the sleeve and defines a seat bearing the sleeve. The other one of these two opposite surfaces defines, between it and a wall of the housing according to the direction of the axis of the sleeve, a free volume wherein exists one of the openings and via which the fluid flows, being distributed over the entire periphery of the sleeve when this sleeve is in its open position.

The invention relates to a valve (3) that comprises a housing (20) and a thermostatic member (52) having a mobile piston (58) that carries a plug (76) for controlling the fluid flow between two accesses to the housing. In order to simplify the manufacture and the maintenance of the valve, inter alia, a hollow body (54) bearing the thermostatic member is adapted both to be rigidly connected to the fixed portion of the thermostatic member so that the piston can extend inside the inner chamber (64) of the body and so that the plug controls the fluid flow through said chamber, and to be received and sealingly blocked in an inner volume (V20) of the housing so that the fluid cannot flow between the two accesses through the chamber, while a thermostatic assembly (50), defined by the bearing body and the thermostatic member connected together, can be urged as a whole into the inner volume of the housing.

A valve comprises a housing, a movable check mechanism that is suitable for regulating passage of a fluid between an inlet orifice and an outlet orifice of the housing, a stationary seat for receiving the check mechanism, and a thermostatic element that is provided with a body, which contains an expandable material, and a movable piston, with this body being stationary relative to the housing. In order to prevent excessive pressure from being generated in the valve, on a side of the check mechanism where the thermostatic element is arranged, the check mechanism and the piston are connected by a part that is integral with the valve and delimits a blind recess for receiving the piston, with a base of the recess forming a stop for the piston when a difference in pressure on either side of the check mechanism is less than a predetermined value, while a wall of the recess forms a surface for sliding contact with the piston when this difference in pressure is greater than this predetermined value.

A cooling circuit comprises a regulating valve, the moving shutoff means of which is actuated by an electric motor the feed current of which is subjected to the action of an electronic control system sensitive to various operating parameters of the internal combustion engine. A safety thermostatic wax capsule is located in a chamber of the valve so as to act on the moving shutoff means so that hot cooling liquid coming from the internal combustion engine is conveyed at least for the most part, towards a radiator only in the case where the temperature of the cooling liquid in the chamber exceeds by a predetermined amount, the temperature for which the electronic system is set.
