Abstract

1,242,643. Priming; carburetter. ZENITH CARBURETTER CO. Ltd. Feb.16, 1970 [Feb.20, 1969], No.9185/69. Headings F1B and F1K. An automatic cold starting device for an internalcombustion engine includes a fuel supply orifice 22 through which fuel is adapted to be drawn by the suction of the engine to which the cold starting device is connected, means 24 for varying the effective area of the orifice and a temperature sensitive device 18 operative to position the area varying means at any given temperature so as to provide an effective area of the orifice, determined by that temperature, the temperature sensitive device also being operative to decrease the effective area of the orifice, with increase of temperature and to close the orifice at predetermined maximum temperature. There are provided spring means 29 to urge the area varying means towards a position in which the effective area of the orifice is a maximum and means 27 actuable by the engine to which the cold starting device is connected when the engine commences to run, to remove the load of the spring means from the area varying means so that the area varying means take up a position determined by the temperature sensitive device and are free to move to reduce the effective area of the orifice under the control of the temperature sensitive device as the temperature increases. The coiled compression spring 29 may be replaced by a torsion spring mounted in the chamber 11. In a modification a further rotatable control member is mounted coaxially with the rotatable members 13 and 30.
