Thermostatic mixing apparatus and a related method for regulating temperature

Claim 2

A thermostatic mixing apparatus primarily intended for use in sanitary installations, comprising a body having two inlets which open respectively into a cold-water admission chamber and a hotwater admission chamber and containing a mixing chamber which opens into an outlet for the discharge of blended water, means comprising a thermostatic cell for regulating the temperature of the mixture and means for controlling the outflow rate, wherein said apparatus comprises a delivery chamber in communication with the mixing chamber and adjustable means for introducing either of the feed water streams directly into said delivery chamber, said body being cylindrical, and a bush mounted in coaxial relation to the body so as to define the mixing chamber and provided with ports for the admission of feed water into the mixing chamber, wherein the bush is adapted to carry a cover pierced by a hole and forming a partition-wall between the mixing chamber and the chamber for the delivery of blended water, and wherein longitudinal gaps for the admission of hot water and cold water directly from the inlets into the delivery chamber are formed in the bush.

Claim 3

An apparatus according to claim 1, wherein castellated recesses providing a connection between the gaps and the delivery chamber are arranged in the cover of the bush.

Claim 4

An apparatus according to claim 1, wherein means are provided for rigidly coupling the bush for rotation with a control knob for regulating the temperature of the blended water.

Claim 5

An apparatus according to claim 1, wherein the gaps of the bush are formed in the vicinity of the ports for admission of feed water.

Claim 6

An apparatus according to claim 1, wherein the delivery chamber is connected to a discharge spout through a pipe in which is mounted a control knob for regulating the rate of flow of blended water.

Claim 7

A thermostatic mixing apparatus primarily intended for use in sanitary installations, comprising a body having two inlets which open respectively into a cold-water admission chamber and a hot-water admission chamber and containing a mixing chamber which opens into an outlet for the discharge of blended water, means comprising a thermostatic cell for regulating the temperature of the mixture and means for controlling the outflow rate, wherein said apparatus comprises a delivery chamber in communication with the mixing chamber, a bush mounted in coaxial relation to the tap body so as to define the mixing chamber and provided with ports for the admission of feed water into the mixing chamber, wherein the bush forms a partition wall between the mixing chamber and the blended-water delivery chamber which is formed between the bush and the tap bodY, wherein peripheral drilled holes open into the delivery chamber and are formed in the bush in the vicinity of its ports for the admission of the feed water and wherein means are provided for displacing the bush axially and in rotation.

Claim 8

A thermostatic mixing apparatus primarily intended for use in sanitary installations, comprising a body having two inlets which open respectively into a cold-water admission chamber and a hot-water admission chamber and containing a mixing chamber which opens into an outlet for the discharge of blended water, means comprising a thermostatic cell for regulating the temperature of the mixture and means for controlling the outflow rate, wherein said apparatus comprises a delivery chamber in communication with the mixing chamber, a bush mounted in coaxial relation to the tap body so as to define the mixing chamber and provided with ports for the admission of feed water into the mixing chamber, wherein the bush forms a partition wall between the mixing chamber and the blended-water delivery chamber which is formed between the bush and the tap bodY, wherein peripheral drilled holes open into the delivery chamber and are formed in the bush in the vicinity of its ports for the admission of the feed water and wherein means are provided for displacing the bush axially and in rotation.

Claim 9

An apparatus according to claim 6, wherein the bush is provided opposite the inlets of the body with an annular projection in which are formed longtiudinal grooves for putting the drilled holes into communication with the blended-water delivery chamber.

Claim 10

An apparatus according to claim 7, wherein the bush is coupled for translational and rotational motion with an operating rod attached to a control knob for regulating the rate of flow and the temperature of the blended water.

Claim 11

A thermostatic mixing apparatus primarily intended for use in sanitary installations, comprising a body having two inlets which open respectively into a cold-water admission chamber and a hot-water admission chamber and containing a mixing chamber which opens into an outlet for the discharge of blended water, means comprising a thermostatic cell for regulating the temperature of the mixture and means for controlling the outflow rate, wherein said apparatus comprises a delivery chamber in communication with the mixing chamber and adjustable means for introducing either of the feed water streams directly into said delivery chamber, said body being cylindrical, and a bush mounted in coaxial relation to the body so as to define the mixing chamber and provided with ports for the admission of feed water into the mixing chamber, wherein the bush is adapted to carry a cover pierced by a hole and forming a partition-wall between the mixing chamber and the chamber for the delivery of blended water, and wherein longitudinal gaps for the admission of hot water and cold water directly from the inlets into the delivery chamber are formed in the body.

Claim 12

A thermostatic mixing apparatus primarily intended for use in sanitary installations, comprising a body having two inlets which open respectively into a cold-water admission chamber and a hot-water admission chamber and containing a mixing chamber which opens into an outlet for the discharge of blended water, means comprising a thermostatic cell for regulating the temperature of the mixture and means for controlling the outflow rate, wherein said apparatus comprises a delivery chamber in communication with the mixing chamber and adjustable means for introducing either of the feed water streams directly into said delivery chamber, said body being cylindrical, and a bush mounted in coaxial relation to the body so as to define the mixing chamber and provided with ports for the admission of feed water into the mixing chamber, wherein the bush is adapted to carry a cover pierced by a hole and forming a partition-wall between the mixing chamber and the chamber for the delivery of blended water, and wherein longitudinal gaps for the admission of hot water and cold water directly from the inlets into the delivery chamber are formed in the body.
