Title: Improvements in and relating to thermostatically controlled valves
IPC: F01P7/16
Filed: 1938-07-14
Abstract: 517,012. Fluid-actuated valves. SAUNDERS, P. K., and SAUNDERS VALVE CO., Ltd. July 14, 1938, Nos. 22614/39, 22450/38, 25127/38 and 459/39. Divided out of 516,499. [Class 135] [Also in Group XIII] A valve for controlling the cooling-system of an internal combustion engine is operated by fluid pressure generated by the engine and controlled thermostatically by a pilot-valve operated by a bi-metallic element. The thermostatic control is independent of atmospheric pressure, and thus renders unnecessary means for compensating for changes in atmospheric pressure. The valve shown in the Figure is arranged in the radiator by-pass and comprises a casing 1 containing a fixed chamber 6 in which is mounted, by means of packing rings 12, 13, a valve-member 11 consisting of a movable cylinder 11 having a conical end 9 for engaging a seat 10 on the casing. A rotary pilot-valve 18 is mounted on a pin 31 in the cylinder and is formed with radial slots 19 which can register with radial slots 19 in the conical end 9. The pilot-valve is operated by a bi-metallic element consisting a coiled aluminium tube 20 containing a steel wire 21. The tube is secured by clamps 22 to the valve-member 11, and the wire is connected at one end to the pilotvalve and is provided at the other end with a nut 38 abutting on the axially arranged end of the tube. The space between the chamber 6 and casing 1 constitutes a Venturi-passage and communicates through ports 30, and a leak-hole 40 adjustable by a screw 39 with the space between the packing-rings 12, 13, and behind the packing ring 13 respectively. Ports 16, 43, 17 permit a small flow of liquid through the valve-member 11. Normally, the ports 19 are open, the valvemember 11 is closed, and liquid circulates through the radiator. When the temperature of the liquid falls below a pre-determined level, the element 20, 21 rotates the pilot-valve, the ports 19 are closed, the valve-member 11 is opened by the pressure of the liquid, and the radiator is bypassed. The temperatures at which the valvemember 11 is opened and closed are determined by adjustment of the screw 39, and a nut 33 in connection with a returning-spring 32 for the valve-member 18. The valve may be fitted in the main duct of the radiator and arranged to open when the temperature rises. The above-described valve may be replaced by a piston-operated valve and an associated pilot-valve operated by a bi-metallic element.

Abstract: 342,749. Vapour burners. SCOTT. SNELL LABORATORIES, Ltd., SNELL, C. SCOTT-, and SNELL, E. SCOTT-, Chandos House, Buckingham Gate, London. May 23, 1930, Nos. 22674/29. [Class 75 (i).] Vaporizing apparatus ; burners, adjusting ; wick burners, flame regulating in; wicks.-Oil drawn up by a wick a, Fig. 1, from a reservoir b, formed with air passages f, is incompletely burnt below a flue h and the combustion products and oil vapour generated at the wick pass from the flue through a perforated plate r into a chimney n where they ascend with air entering through a perforated plate t and the apertured chimney base member k. The vapour and air are thoroughly mixed on issuing through lateral openings s at the top of the chimney n which is of at least four times the height of the flue h. The wick is preferably formed of a number of strips of asbestos, cotton, bath brick, or kieselguhr having a total width of four inches and is mounted in a rectangular carrier c which can be raised or lowered by a lever d operated by a hand-screw e. The flue h and the wick carrier c are formed with oppositely disposed shelves i, j. At starting, the wick is ignited in its lowest position and the chimney n is turned in the base-member k to close the air apertures m. When the parts have become sufficiently heated the wick is elevated by the screw e to reduce the air passage between the shelves i, j and the chimney n is turned to open the apertures m. The gases issuing from the openings s may then be ignited. The wick carrier may be fitted with rods g carrying flaps which may be turned to regulate or extinguish the flame. The chimney may carry an incandescent mantle. Fig. 3 shows the flue h discharging into a universally adjustable conduit 3 carrying an adjustable blowpipe burner tube 6 fitted with a choke tube 7 and a discharge nozzle 4 in alignment with a compressed air or oxygen nozzle 5. The wick burns when " idling " only along a central notch 2 in the wick guide. When compressed air is supplied to the nozzle 5 the increased draught causes the flame to spread along the length of the wick and induces a flow of air through a slot 16 in a tube 17 below the burner tube 6 to mix with the vapours ascending from the wick. The mixture burns mainly at the nozzle 4 but part passes through an annular opening 9 around the nozzle and burns at perforations 14 in a flange 8 on the nozzle thereby preventing accidental extinction of the main flame. On the compressed air supply being cut off vapours pass through perforations in a tube in the tube 17 and burn at the slot 16 to keep the nozzle 4 hot. In a modification an annular member may be adjusted to divert more or less of the mixture to burner openings below the nozzle 4.
