Abstract
A torque motor and throttle body are integrated within a single assembly for application with an internal combustion engine charge air inlet. The butterfly valving element of the throttle body and rotor of the motor are mounted on a common shaft, the position of which is established by a fly-by-wire control circuit. The control circuit includes a driver which selectively energizes the motor in response to the simultaneous receipt of both duty cycle and pulse with information. The control circuit further provides redundant outputs and transducers to enhance system failsafing.
