Abstract

1,096,772. Valves. ECLIPSE FUEL ENGINEERING CO. March 25, 1965, No. 12738/65. Heading F2V. A low pressure gas-regulating valve comprises a closure member 28 carried by a stem 30 attached to a diaphragm 40 and carrying a cotter-pin 82 which co-operates with the long arm 76 of a lever 72 pivoted at 74, a short arm 78 of the lever abutting a spring 70 to enable the latter to seat the closure member. A passage 46 connects the outlet 16 to the space beneath the diaphragm, the space above the diaphragm being connected to atmosphere via a bleed 43. The spring may be replaced by a weight adjustable along the arm 78. In operation, in its idle condition, the closure member rests lightly against the seat. When the inlet 18 is connected to source, the pressure in the inlet chamber acts on sealing diaphragm 55 to maintain the valve closed. Flow to the outlet occurs when the pressure therein is reduced sufficiently to allow the pressure difference across diaphragm 40 to unseat the closure member. If the demand at the outlet increases. the leg 47 of passage 46 reflects the velocity pressure to chamber 42 to increase the degree of opening of the valve.
