The present invention refers to a dual control thermostatic mixer with a regulator suited to stabilize the mixed water temperature upon exit, using a stabilizing mechanism and a switching device for choosing either spout or handset flow. It has a main body (A), a close, setting and commutation valve (B), a switch handle lever (C) and a water temperature-regulating knob (D). The main body of the mixer (A) has central part internally divided and separated by four ringed chambers were the switching valve set (B) operates. The switching valve set is made of a thermostatic regulator and a switching device that allow to regulate the water's temperature keeping it constant for use with a handset or directly to the spout.
1- Dual control thermostatic mixer with a thermostatic regulator suited to control the mixed water temperature upon exit, using a stabilizing mechanism and a switching device for choosing either spout or handset flow. It has a main body (A), a switching valve set (B), a switch handle lever (C) and a water temperature-regulating knob (D).
2- Dual Control Thermostatic Mixer, according to claim 1, characterized in that the body of the main valve-set is made of brass or composite nylon-fibreglass materials.
3- Dual Control Thermostatic Mixer, according to claim 1;
4- Dual Control Thermostatic Mixer, according to claims 1, 2 and 3;
5- Dual Control Thermostatic Mixer, according to claim 1, characterized in that the switch valve (3) moves in an axial way along the switch capsule (2) from 8 mm to 12 mm, preferably 10 mm when the switch handle turns from 90°.
6- Dual Control Thermostatic Mixer, according to claims 1 and 5, characterized in that the switch valve (3) presents on the upper part a 4 way exterior thread with a 5 mm pitch were the switch capsule (2) fits. This capsule has an inner 4-way thread also with a 5 mm pitch at the lower part.
