Throttle assembly for internal combustion engine, and throttle sensor |
摘要 |
In a throttle body there are provided a throttle valve for controlling the flow of intake air in an internal combustion engine, an electrically-driven actuator for actuating the throttle valve, and a reduction gear mechanism for the actuator, and a receptacle portion for receiving the reduction gear mechanism therein is formed in a side wall of the throttle body. A cover which covers the receptacle portion is attached to a side wall of the throttle body. The throttle assembly of the invention is provided with a potentiometer type sensor for detecting the degree of opening of the throttle valve, the sensor comprising a slider and a resistor, the slider being adapted to slide on the resistor and mounted to a peripheral surface of a driven gear so that a tip end thereof faces in a radial direction of a throttle valve shaft, the driven gear being disposed on the throttle valve shaft side of the reduction gear mechanism. On the other hand, the resistor is constituted by a curved resistor which confronts the slider in the said radial direction. A wall portion which holds the curved resistor is formed by molding integrally with the aforesaid cover.
