Abstract (en)
[origin: EP1188991A1] The valve comprises first (20) and second (21) bodies whose first ends (22,23) are connected respectively to the heating circuit return and to a cold water inlet pipe. Their second ends (24,25) are connected respectively to a hydraulic motor driving a valve set (26) between two seats opening and closing orifices located within the valve, and a pressure difference generator system (29) comprising a restriction (16). The generator system comprises a casing having two pressure tappings (38,39) connected to upstream and downstream chambers of a motor enclosure and an outlet orifice to the bathroom exchanger. The exchanger return orifice is positioned on a third transverse body and discharges into the first body which also has heating circuit outlet orifice.
