Abstract
PURPOSE:To make it possible to control the suction amount highly accurately and minutely by adding dither control units to control the duty ratio of the control signal to a control device to control a throttle valve through driving a stepping motor. CONSTITUTION:A throttle valve M3 held by a rotary shaft M2 is furnished in a suction passage M1. On the other hand, a stepping motor M8 to drive a rotor M5 which furnishes an output shaft M6 linking to the rotary shaft 2 by converting the excitation to plural magnetic poles M7 is provided. And a control device M9 to control the stepping motor M8 is also provided. In such a composition, the first dither control unit M10 to control the duty ratio of the control signal delivered to the neighboring magnetic pole M7 is arranged. The second dither control unit M11 to add the control signal of the controlled duty ratio to the magnetic poles M7 including the magnetic pole 7 close to the rotor M5 is also arranged.
