A hot water circulation system comprises a water heater having a cold-water inlet and a hot water outlet. A water pump circulates water through the water heater to produce hot water. The hot water is circulated to a thermal bypass valve, which is configured to close when hot water contacts a heat activated seal. A bypass circuit is coupled between the hot water outlet and the cold water inlet of the water heater. The bypass circuit prevents hot water from circulating from the hot water outlet to the cold-water inlet when the thermal bypass valve is open and promotes circulating hot water from the hot water outlet to the cold water inlet when the thermal bypass valve is closed. Upon a temperature sensor sensing hot water entering the cold-water inlet, the water heater turns of the water pump.

This cartridge comprises a base (10), a fixed attached piece (20), a spool (30) for controlling the temperature of the mixture of the hot and cold fluids, and a thermostatic element making it possible to move the spool along an axis. The base simultaneously delimits an outlet orifice (16) for the mixture, an inlet orifice (14) for the cold fluid that supplies, via a first distribution channel (F4), cold fluid around the spool, a passage (F3), delimited axially between the spool and the base, and an inlet orifice (15) for the hot fluid that supplies, via a second channel (C4) for distribution hot fluid around the spool, a passage (C3) delimited axially between the spool and the attached piece. In order for the base to remain simple and cost-effective to produce, while still favoring the flow of high fluid flow rates through it, the invention proposes to close, axially toward the outlet orifice, the first distribution channel by means of the spool and the second distribution channel by means of the attached piece.

Thermostatic cartridge for a mixing valve for mixing a cold incoming fluid and a hot incoming fluid in a determined proportion to form a mixture. A head includes a housing extending along a central axis, and a thermostatic regulating assembly. A regulating system defines an abutment surface adjustable in axial translation with respect to the head. A thermostatic system includes a heat sensitive first portion over which the mixture can flow, and a second portion to abut axially against the abutment surface. The first portion can move the second portion axially between plural positions relative to the first portion, the relative positions determined by the mixing temperature. A slide mounted on the first portion moves axially relative to the head for modifying the determined proportion, and may slide between a normal position and plural overtravel positions axially closer to the head than the normal position.

A fitting device for delivering mixed water, comprising a first inflow line for feeding hot water and a second inflow line for cold water, wherein the first and second inflow lines lead into a mixing chamber for mixing cold and hot water, wherein provision is made of a first shut-off device for controlling and/or for shutting off the flow from the first inflow line into the mixing chamber, wherein the first shut-off device has a temperature-sensitive element to control the flow from the first inflow line in a manner dependent on the temperature, wherein the second inflow line has an inflow to the mixing chamber that is formed independently of the first shut-off device, wherein the mixing chamber has an outlet line for the outflow of the mixed water, wherein provision is made of a temperature-setting device for setting the temperature of the mixed water.

For the single-handle dual-control thermostatic valve and the faucet, a hot water incoming channel, a hot water outgoing channel, a cold water incoming channel and a cold water outgoing channel are provided in the valve core body respectively. A static ceramic chip is provided above the valve core body in the valve jacket, a dynamic ceramic chip is provided on the static ceramic chip. On the static ceramic chip, a hot water inlet passage, a hot water outlet passage a cold water inlet passage and a cold water outlet passage are provided separately, the hot water inlet passage, the hot water outlet passage, the cold water inlet passage and the cold water outlet passage are connected correspondingly with the hot water incoming channel, the hot water outgoing channel, the cold water incoming channel and the cold water outgoing channel of the valve core body respectively. On the dynamic ceramic chip, a hot water controlling channel and a cold water controlling channel are provided. The hot water controlling channel can open or shut off both the hot water inlet passage and the hot water outlet passage on the static ceramic chip, and the cold water controlling channel can open or shut off both the cold water inlet passage and the cold water outlet passage on the static ceramic chip. The dynamic ceramic chip in the present invention does not change the flow of hot water and cold water into the regulator during its rotation, the hot incoming water and the cold incoming water can be opened or shut off by the sliding dynamic ceramic chip so as to regulate the water flow.

The hot and cold water mixing valve device includes a hot and cold water mixing valve unit; a flow control valve unit; a valve device main body; a hot and cold water mixing valve housing; and a flow control valve housing; and wherein the valve device main body includes: a hot water passageway permitting communication between only the hot water inlet of the valve device main body and the hot water inlet of the hot and cold water mixing valve unit; and a cold water passageway permitting communication between only the cold water inlet of the valve device main body and the cold water inlet of the hot and cold water mixing valve unit are formed on the interior of the valve device main body.

This cartridge comprises a housing, a base, attached to the housing and enclosing a chamber for mixing a cold fluid and a hot fluid, a thermostatic control system, arranged in the chamber and capable of controlling the temperature of the mixture leaving the chamber to a setpoint temperature, and a flow rate adjustment system, suitable for adjusting the flow rate of the mixture from outside the housing. This adjustment system comprises both a control member, which is able to move at least partially inside the housing in such a way as to vary the flow rates of cold fluid and hot fluid supplying the chamber, and an adjustment ring, which is arranged outside the housing and is centred on an axis (X-X) around which this ring is able to rotate relative to the housing, the ring being connected, through the housing, to the control member, by a connecting member.
