Abstract
864,589. Valves. FRESSON, N., and TRUBERT, D. Jan. 7, 1959, No. 655/59. Class 135. A water-mixing device for delivering either a mixture of hot and cold water at a desired temperature or cold water alone, comprises a tubular valve body 1, Fig. 1, having parallel ducts 2, 3, hot and cold water inlets 5, 6 connected to the duct 2 and a delivery outlet or outlets (not shown) connected to the duct 3. Ports 13, 14 interconnecting opposite ends of the ducts 2, 3 are controlled by hot and cold water cocks 11, 12 respectively, screw actuated from outside the body. A tubular member 21 fixedly mounted in the duct 2 to directly isolate the inlets from each other constitutes a mixing chamber and houses a thermostatic member 29 filled with an expansible liquid introduced through a neck 39 which is closed by a plug 41. The neck 39 carries a slide valve 28 co-operable with slots between fins 27 in a plug 24 closing the valve body 1 and sealingly fitting the tubular member 21. To supply hot water the cock 11 is opened whence hot water from the inlet 5 passes through holes 45 into the tubular member and thence through the port 13 and the outlet. The desired operating temperature is adjusted by a a graduated knob 35 which on rotation moves a non-rotatable screw 34 towards or away from a bellows 30 of the thermostatic member. If the temperature of the water is above that desired, the thermostatic member moves rightwardly against its spring 32 to open the valve 28 to pass cold water into the mixing chamber through a check valve 42. When cold water only is required the cock 11 is closed and the cock 12 opened, hot water entering the mixing chamber closes the check valve and cold water passes directly from the inlet 6 to the outlet.
