摘要： A throttle gear 5 is fastened to a throttle shaft 2. A relief lever 9 is pivotally mounted on the throttle shaft 2. A return spring 11 urges the relief lever 9 in a valve closing direction with respect to a throttle body 1. The throttle body 1 contacts the relief lever 9 at a second contact position 20A when the relief lever 9 pivots to a predetermined pivot position B in the valve closing direction. A relief spring 10 urges the throttle gear 5 in a valve opening direction with respect to the relief lever 9. The relief lever 9 contacts the throttle gear 5 at a first contact position 20B when the throttle gear 5 pivots to the predetermined pivot position B in the valve opening direction. The first and second contact positions 20B, 20A are located within or to one side of a plane P that is perpendicular to the rotational axis L of the throttle shaft 2. Plane P preferably includes a third position 20C at which the biasing force of the return spring 11 acts on the relief lever 9.

摘要： A throttle control apparatus for an internal combustion engine in which wear particles due to sliding between components and vibration wear particles produced between components by engine vibrations are prevented from entering the area between a brush of a throttle sensor and a sensor substrate to prevent the occurrence of a contact failure between the brush and the substrate, thereby making it possible to detect an accurate throttle opening. A brush of a sensor unit is secured to an outer end portion of a throttle shaft projecting from a cover, and the sensor unit is accommodated in a sensor chamber formed outside the cover. A gear chamber for accommodating gears and the sensor chamber are isolated from each other by a dust seal. Therefore, wear particles will not enter the sensor chamber and accumulate in the area between the brush and the sensor substrate to cause a contact failure.
摘要翻译：一种用于内燃机的节气门控制装置，其中防止由于部件之间的滑动引起的磨损颗粒和通过发动机振动在部件之间产生的振动磨损颗粒进入节气门传感器的刷子和传感器基板之间的区域，以防止发生刷子和基板之间的接触故障，从而可以检测出精确的节气门开度。传感器单元的刷子被固定到从盖突出的节流轴的外端部，并且传感器单元容纳在形成在盖外部的传感器室中。用于容纳齿轮的齿轮室和传感器室通过防尘密封彼此隔离。因此，磨损颗粒不会进入传感器室并积聚在电刷和传感器基板之间的区域中，导致接触故障。
