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 rotor is selectively affixed to the shaft through an intermediate coupling which is excessible externally of the motor's closed stator assembly.
