Abstract

1493533 Automatic choke valves FORD MOTOR CO Ltd 21 Feb 1975 [20 March 1974] 7453/75 Heading F1H [Also in Division H1 ] In an automatic thermostatically choked carburetter, having a thermal element actuated by heated air drawn from the area of the exhaust system past the element by the manifold vacuum, below a preselected temperature an auxiliary heating device is actuated to heat the element, in response to the manifold vacuum falling below a level sufficient to maintain the hot air-flow over the element. The thermal element comprises a coiled spring 60, mounted on a heat sink 85. The auxiliary heating device 86 comprises a positive temperature coefficient resistor connected via a bridging-type vacuum switch 102 to a current supply terminal 100, the switch being biased to the closed position by spring 118. A bi-metallic thermal switch 94 selects whether the vacuum switch is by-passed thus operating the heater continuously above the pre-selected temperature, Fig. 2, (not shown). The operation of the spring 60 is modified by a choke cracking arrangement comprising a piston responsive to manifold vacuum, Fig. 1, (not shown). The system is said to compensate for altitude changes.
