Abstract

1,229,162. Valves. CARLO GAVAZZI S.p.A. 3 April, 1969 [3 April, 1968], No. 17440/69. Heading F2V. [Also in Division G3] A valve for regulating pressure, temperature or humidity in an air-conditioning system has a diaphragm 2 actuated by a fluid-pressure corresponding to the variable to be controlled and two valve plugs 13, 19 slidably mounted on a stem 8 to operate successively and add cold or hot water to the recycled water in the system, the plugs being separated by a piston 22. As the diaphragm moves the valve stem 8 downwardly, the plug 19 is moved by a spring 21 to open a port 23 and allow recycled water from an inlet 27 to be mixed with hot water from an inlet 25 flowing into an outlet 26. After there has been sufficient downward movement of the stem to interrupt the flow of hot water by closing a port 16, a ring 12 engages the plug 13 and opens a port 16 to allow cold water from an inlet 30 to be mixed with recycled water from an inlet 28 flowing into an outlet 26 until the downward movement has sufficiently compressed a spring 15 to close a port 24 for the recycled water. The stem 8 and port 16 are of stainless steel and the plugs of stainless steel or bronze with inserts 14 of neoprene or "Teflon" (Registered Trade Mark). A cap of hot-pressed light alloy encloses the diaphragm which may also be of neoprene.
