摘要： Control apparatus, typically for carburettors, which comprises an actuator device (20) having a permanent magnet armature and a pair of coils surrounding the permanent magnet, and a microprocessor (18) responsive to certain parameter-sensed variables including pressure (12), temperature (14), throttle conditions (16) and oxygen content (10) in order that these variously sensed parameters can be com- municatedtothe microprocessor wherein there is transduced by algorithm either a digital signal or an analog signal. The digital or analog signal is then fed to the actuator device in the form of a demand signal for currentflowto the armature coils. The coils upon energisation mechanically displace the arma- tureto effect mechanical transducing ofthe electrical signal to control an actuator rod effecting orifice control. The armature thus effectively controls the orifice size, which in turn determines fuel/air ratio for an internal combustion engine, in conjunction with a carburettor function. Fuel-air control creates operating conditions which in turn are re-sensed by the sensors, the sensors in turn repeating their operation so that there is provided a closed loop servo system either by digital oranalog signals.
