Abstract: 109,534. Gaisman, H. J. Nov. 16, 1916. S p r a y carburettors; vaporizers, external.-The fuel valve of a carburettor is controlled. by a thermostat subjected to the heat of a casing containing the mixture chamber, so as to supply less fuel as the mixture becomes warmer. The charge passing to the engine is heated by the exhaust gases to a variable degree by causing it to pass over a larger or smaller heated surface. For this purpose, the charge is passed through a hollow plug 30, Fig. 2, the outlet 31 of which can be directed to different parts of a curved passage 29 in a chamber 6 adjacent to an exhaust chamber 2. The plug is rotated by means of a wire coiled round it. The thermostat 17, Fig. 6, which is attached to the underside of the chamber 6, consists of strips of different metals connected to the valve stem 12 by a wire clip 18 which can be adjusted and is capable of yielding under abnormal circumstances. After the engine has warmed up, the fuel valve closes to an extent limited bv a stop 22, reducing the supply of fuel. The carburettor may have a second uncontrolled fuel passage, in which case the valve may be closed entirely by the thermal element, the stop being dispensed with. The wire clip- 18 may be replaced by an adjustable screw in the element 17 against which a shoulder on the valve stem is held by a spring.
