Filed: 1938-01-29
Abstract: 510,335. Valves. HOLM, C. B. Jan. 29, 1938, No. 2898. [Class 135] [Also in Group XI] Liquid fuel is supplied under pressure to the vaporizing chamber 1 of a vapour burner through a casing 6 fitted with a control valve opened or closed in accordance with the pressure in the chamber 1. The casing 6 is divided by diaphragms 44, 39 into three chambers 36, 40, 41. The diaphragm 39 carries a tube 42 having small apertures 49 at its upper end which projects through a ring 46 attached to a member 45 secured to the diaphragm 44. The vaporizing chamber 1 consists of a large upper portion 3 fitted with a valve controlled nozzle 8 and a smaller lower portion 4 connected by a pipe 5 to the chamber 41. -At starting the fuel entering the chamber 40 through the pipe 7 presses the diaphragms 39, 44 apart against the action of springs 52, 53 and causes the tube 42 to engage with an adjustable valve body 51 and a flange 57 on the members 45 to engage a spring- pressed ring 55. When the fuel already in the chamber 1 becomes vaporized by burning alcohol in a starting cup the back pressure depresses, the fuel to the level 32 and causes the diaphragm 39 to lift the tube 42 above the valve 51. Fuel can now flow through the tube 42 to the chamber 1. Vaporization is then continued by the heat conducted from the burner flames to the chamber 1 by a plate 31. When the nozzle 8 is closed vapour condenses in the chamber 1, the diaphragm 39 moves the tube 42 into engagement with the valve 51, and the fuel is restored to the level 63 suitable for restarting. Fuel is admitted to the chamber 1, if empty, by raising the member 45 by means of a hand-lever 60. The stem 9 of the valve controlling the nozzle 8 is mounted non-rotatably in a tube 10 secured in the chamber 1. sealing being effected by a bellows 22. The stem 9 is threaded in a screw 14 which is oppositely threaded in a nut 15 on a fixed wall 12. An operating button 11 on the stem 9 is slidable on a rectangular extension 16 of the screw 14 against the resistance of a spring 18. The rotation of the button 11 beyond maximum and minimum flame positions is normally limited by a projection 19 carried by the button engaging fixed abutments 20, 21, but the button may be pulled out against the resistance of the spring to pass the abutment 21 when the valve is to be moved to or from the closed position.
