摘要

Improvements in the hot and cold water mixing valves, constituted by an empty casing that delimits a mixing chamber within which the two fluids arrive in variable quantity, in relation to the opening of their adduction ducts, opening that is regulated by a single shutter element in turn requested by a thermostat housed inside the same mixing chamber, characterized in that the valve comprises: - a substantially cylindrical casing (1) provided with a circumferential throttling in correspondence with which the two hot and cold water pipes (7, 8) arrive, - a shutter (17) substantially cylindrical, axially movable within said throttling and provided with two terminal tabs (19, 20) for the watertight support to the edges of the carcass part (4) forming the same throttle, subdividing said shutter the internal space of the housing in two chambers (5, 6) one of which (5) constitutes the mixing chamber, - at least one joint (13) interposed between the obturator (17) and the casing (1) in correspondence with the throttling, - a thermostat (27) housed in the mixing chamber (5) and having the sensitive element (28) movable axially with respect to the housing (1) and suitable for requesting one of the two ends of the shutter, - means (23) of antagonism to the loads of the thermostat, - at least one conduit (22) for direct communication between the two chambers (5, 6).
