Abstract
779,201. Valves. BRITISH THERMOSTAT CO., Ltd. Oct. 25, 1955 [Nov. 5, 1954], No. 32124/54. Class 135. A combined metering and shut-off device more particularly for controlling the supply of liquid fuel to burners comprises a metering valve 1 controlling the outlet from a float chamber 7, a floatoperated shut-off valve 9 controlling the inlet to the float chamber, and interconnecting means between the two valves whereby the shut-off valve 9 is caused to be closed by operation of a rotary manual control element 4 of the metering valve to the fully closed position. The metering valve and its actuating mechanism are as described in Specification 720,618, comprising a rotary snail cam 5 acting on a lever 6 to raise the valve against a loading spring 2. The shutoff valve 9 is urged towards closure by a weight 10 carried by a pivoted arm and opened in response to a fall of level in the float chamber by a float 12 mounted on a pivoted arm 11 which engages a pin 13 on the valve. Should the valve fail to seat effectively, the consequent rise of liquid level causes the float to engage a lever 16 to move an abutment 17 out of engagement with a lever 14 whereby the latter is brought by a spring 15 into engagement with the pin 13 to close the valve. Rotation of the element 4 to close fully the metering valve 1 brings a projection 20 into engagement with a lever 21, 22 which engages the float arm 11 to raise the float and release the lever 14 for closing the valve 9. A member 19 is operable to reset the release mechanism 14, 17. A filter 8 is fitted in the inlet to the float chamber. In a modification, the lever 6, when moved to the fully closed position of the metering valve, engages the lever 16 to trip the mechanism 14, 17.
