Abstract: A thermostatic single-control cartridge is provided with ceramic discs with a member for controlling a flow rate and a temperature of a mixed fluid by moving a thermostatic element, thus adjusting the temperature of the mixed fluid between end adjustment positions, an overtravel spring inserted between a regulating slide valve and the thermostatic element being compressed by an overtravel between the end adjustment positions. A retractable blocking system temporarily blocks the temperature adjustment of the mixed fluid in intermediate position of the control member between the end adjustment positions, so as to cut the overtravel in half in the intermediate position.

Abstract: The present invention relates to a thermostatic single-control cartridge provided with ceramic discs with a member for controlling a flow rate and a temperature of a mixed fluid by moving a thermostatic element, thus adjusting the temperature of the mixed fluid between end adjustment positions, an overtravel spring inserted between a regulating slide valve and the thermostatic element being compressed by an overtravel between the end adjustment positions. Retractable blocking means temporarily block the temperature adjustment of the mixed fluid in intermediate position of the control member between the end adjustment positions, making it possible, in said intermediate position, to cut the overtravel in half compared with the existing prior art systems.

Abstract: The cartridge comprises a body in which there is formed a mixed fluid chamber; a fixed disk; a movable disk; thermostatic regulation means including a regulation slide-valve and a thermostatic element which are mechanically connected to each other; and a single control lever for controlling the flowrate and the temperature of the mixed fluid and adapted to drive the movable disk in rotation and in translation and to move the thermostatic element inside the mixed fluid chamber. Cold fluid inlet passage and cold fluid return passage in the fixed disk extend approximately end-to-end in circumferential arcs with substantially equal radii and hot fluid inlet passage and the hot fluid return passage in the fixed disk extend approximately end-to-end in circumferential arcs with substantially equal radii. Application to the field of mixer taps.

Abstract: In a valve member adapted to co-operate with an annular seat and comprising a plate with an annular channel for receiving a gasket which is crimped by folding in an outer wall of the channel, any risk of the gasket being ruptured is minimized by the outer surface of the gasket presenting, in the absence of any stress being exerted thereon, a first region extending frustoconically towards the central axis of the valve member, which first region is extended by a second region extending frustoconically away from the central axis, and by the outer wall of the channel being folded progressively towards the first region so as to fit snugly against the shape thereof without penetrating into the material of the gasket, without exerting any stress thereon, and without compressing it. The valve member is suitable for use in particular in thermostat valves.

Abstract: To obtain an exact regulation of temperature, a strong flow, and a moderate cost, the cartridge comprises a first disc having two transverse hot fluid passages and two transverse cold fluid passages as well as a groove, the base of which forms a seat for a regulating valve which is joined to a thermostatic element, and a second disc having two passages for hot and cold fluid respectively, and which is coupled and rotatable relative to the first disc, between a communicating position and a non-communicating position of the two hot fluid passages on the one hand and the two cold fluid passages on the other of the first disc. The cartridge may be used for thermostatic water mixer taps, in particular for sinks, washbasins, showers and bathtubs.

Abstract: A device, which can be used in the cooling circuits of internal combustion engines comprises a chamber (3) having at least three ports (4, 5, 6) two of which can be closed off by valves (9, 10) carried by a main thermostatic element (7) housed partially in the chamber. One valve moves away from its seat when the other moves towards its own seat. A pipe (1) entering the chamber (3) via one of the two seats contains a thermostatic threshold-setting element (17) carrying a moveable compensator (21) provided with a moveable stop (16) for the main thermostatic element (7). The thermostatic setting element (17) has an electrical heater which can be connected to an electrical power supply that can be selectively activated and deactivated in order, when deactivated, to decrease the distance between the stop (16) and the seat (14) in the pipe and thus the temperature for which this seat is released.

Abstract: A thermostatic element includes an elongated cap, containing a material expandable and contractible as a function of the direction of variation of its temperature. A piston moveable in the longitudinal direction of the cap is coupled to the expandable and contractible material so as to be displaced in opposite directions, depending on whether the material expands or contracts. The side wall of the cap has flats or depressions around the cap and which extend in the longitudinal direction of the cap and which delimit an inner space. The cross section of the inner space, the length over which the flats or depressions extend, has a lobed shape, and an insert accommodated and fixed in the cap extends in the longitudinal direction of the latter.

Abstract: The device comprises a chamber (3) having at least three ports (4, 5, 6) two of which can be closed off by valves (9, 10) carried by a main thermostatic element (7) housed partially in the chamber, one valve moving away from its seat when the other moves towards its own seat.

Abstract: The invention relates to a reverse-flow cartridge comprising a body (1) at which a cold fluid inlet duct (F), a hot fluid inlet duct (C) and a duct (M) for discharging mixed fluid terminate. According to the invention, a bypass (B) connects the cold fluid inlet and mixed fluid outlet ducts, and the cartridge is equipped with a device (7, 8) for shutting off the bypass, this device comprising a thermostatic element (7) equipped with a shut-off element (74) for shutting off the bypass as long as the temperature of the discharged fluid remains below or equal to a predetermined temperature and uncovering the bypass when the temperature of the fluid becomes higher than this temperature so as then to cause fluid to flow from the cold fluid inlet duct (F) to the discharge duct (M) through the bypass (B). The invention can be used in particular in water-distribution installations.

Abstract: A safety cartridge for thermostatic mixer taps includes a thermostat carrying a slide having two valves for shutting off respective flows of hot and cold water. A region of the thermostat is housed in a piston having a part which is guided by a reversibly releasable guide mechanism adapted to guide the piston as long as the valve for shutting off the flow of hot water is not in contact with its seat, to eliminate the guidance when the valve bears on the seat, to allow misalignment of the piston, of the thermostat and of the slide so that the valve is pressed against and sealed to the seat, and to re-establish the guidance when the valve leaves its seat.

Abstract: A thermostat comprises a case (1) forming an elbow through which extends a fluid passageway 2 comprising a fluid inlet region (22) and a fluid outlet region (21) and containing a thermostatic element (3). The thermostatic element (3) includes a fixed part (31), a movable part (32) which carries a closing device (4) cooperating with a seat (23), a bridge (5) in which the movable part (32) is slidable, and a spring (6) biasing the bridge (5) away from the closing device (4). The case (1) is in one piece; the fixed part (31) bears against the wall of the passageway (2); the inlet region (22) comprises inwardly extending projections (19) for blocking movement of the bridge (5) caused by the spring before mounting the thermostat on a support.
