Title: Improvements in and relating to valve apparatus for the supply of fuel from high pressure reservoirs
IPC: F16K17/00
Filed: 1937-02-12
Abstract: 488,874. Valves. CALOR-GAS (DISTRIBUTING) CO., Ltd., and SMITH, H. E. Feb. 12, 1937, No. 4232. [Class 135] Means for automatically changing-over the supply of gas to a lamp or heater from one storage cylinder to another, when the pressure in the cylinder in use falls below a predetermined amount, comprises a hollow fitting having an outlet 1 which is connected to the lamp &c. and which is in communication with inlets 2 and 3, to which the cylinders are connected, through lift valves 5 and 4 respectively. Each valve is spring-closed and opens under the pressure of the gas in its respective cylinder acting on the valve and on a diaphragm 10 secured thereto. Stems 20, 21 projecting from the valves coact with cam surfaces 14 on a plate 12 which is rotatable, between stops 17, 18, on a pin 11 secured to the fitting and which is urged towards the valves by a spring washer 13. Assuming that gas is being supplied through the inlet 3, the valve 4 is open and its stem 20 extends at the side of the plate 12 so as to lock the latter against the stop 18, as shown by dotted lines in Fig. 2, the valve 5 being held closed by the corresponding cam 14 acting on its stem 21. A torsion spring 16 secured to the plate 12 and hooked around the stop 17 tends to turn the plate clockwise. When the pressure in the inlet 3 falls below a predetermined amount, the valve 4 closes, thus releasing the plate 12 which turns until it engages the stop 17. Valve 5 is thus permitted to open and valve 4 is held closed by the corresponding cam 14. The exhausted cylinder may now be replaced by a full one, and the apparatus is reset by hooking the spring 16 on to the stop 18 instead of the stop 17. The Provisional Specification describes an arrangement in which the cam plate is biassed by a weighted arm coacting with pins on the plate and in which a single plunger responsive to the gas pressure in the outlet serves to lock and release the cam plate. It also describes a threeway cock by which either cylinder may be connected to the heater &c., the cock being biassed by a weight or spring but normally locked against its bias by the gas pressure.
