Abstract

1,253,582. Valves. SAUNIER DUVAL. 27 Feb., 1969 [29 Feb., 1968], No. 10672/69. Heading F2V. A closure device for a flow regulator in a water heater has a piston 1 freely slidable in a sheath 3 and a split ring 4 received in a groove in the sheath or, as shown, a groove between the sheath end and an annular cover 7. The ring acts to seal the piston to the sheath and as a scraper to remove deposits from the piston. The piston is actuated by a diaphragm 2 responsive to water flow in a Venturi tube downstream of the piston and seats in the orifice of the seat 10 in its outermost position.
