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.

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.

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.

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.

The inventive thermostatic element comprises a cup (1) containing a material (3) which is expendable and contractile according to the direction of the temperature variation thereof and a piston (5) which is movable with respect to the cup in the axial direction (X-X) thereof and is coupled to the expendable and contractile material in such a way that it is displaceable in the opposite direction according to the material expansion or contraction. In order to reduce the element response time in a simple and reliable manner, the cup (1) is embodied in one metal piece which internally delimits at least two distinct internal cavities (14A) for receiving at least one part of the expendable and contractile material (3).

The cartridge comprises two ceramic disks (20, 24) for regulating the temperature and flow of a mixture (M) of two entering fluids. In order to ensure that the temperature of the mixture remains lower than a predetermined value, the cartridge comprises thermostatic means (16) designed for, in the event of a high-temperature mixture, automatically shutting off, upstream from these disks, the circulation of the entering fluid (C) of the highest temperature. In order to limit their size, these means comprise: a closure element (34), which serves to close a passage (56) of the fluid (C) having the highest temperature and which is delimited by the cartridge, and; a thermostatic element (36) including a thermosensitive part (38) placed along the flow path of the mixture and a mobile part (40) connected in translation to the closure element, said closure element being mounted in a manner that enables it to slide in an area (42A) of the passage of the fluid of the highest temperature, with the interposition of a packing seal (58), which is joined to this area and which, when the temperature of the mixture is greater than the predetermined value, is capable of forming a sliding tight contact with the closure element.
摘要:
The thermostatic cartridge (C) comprises a thermostatic assembly (2) for regulating the temperature of an outgoing mixture (F3) of incoming hot and cold fluids (F1 and F2), two ceramic disks (3, 4) for controlling the flow rates of the hot and cold fluids delivered to the thermostatic assembly, and a disk-actuating sleeve (5) receiving therein in leaktight manner the outer body (2.1) of the thermostatic assembly. To limit costs and any risk of leakage from the cartridge, the actuator sleeve is a single part that defines two internal channels (52, 53) for passing flows respectively of the hot and cold fluids from the disks to respective admission slots (2.2, 2.3) defined by the outer body of the thermostatic assembly.

摘要:
A thermostatic cartridge regulates hot and cold fluids to be mixed, and a mixer tap one such cartridge. The cartridge includes two disks which are used to adjust the flow of hot and cold fluids and which each include a passage for hot fluid, a passage for cold fluid, and a passage for a mixture of both. The disks are movably joined to one another. One of the disks is connected in rotation to a member for controlling the flow of the mixture, while the other is fixed. In order to do without a turbulator in the cartridge, the flow section for the mixture through the disks, which is defined by stacking passages for the mixture in the joining plane of the disks, varies according to the configuration of the control member. The majority of the thermo sensitive part of a thermostatic regulation element is positioned upstream of the disk joining plane in the direction of flow of the mixture.
