    • A sensor for a throttle control device. The throttle control device includes a throttle body. A throttle valve is disposed within an intake air channel defined within the throttle body. A speed or gear reduction mechanism is coupled between a motor and the throttle valve. A sensor detects the rotational position, i.e., the rotational angle, of the motor and has a movable section and a fixed sensing section. The movable section is attached to a rotary shaft of the motor, so that the movable section rotates as the rotary shaft rotates. The fixed sensing section is mounted to the throttle body and is disposed within the movable section. By detecting the rotation of the motor a computing section can accurately determine the degree of opening of the throttle valve. The sensor outputs the degree of opening of the throttle valve.
    • 用于节流控制装置的传感器。 节气门控制装置包括节气门体。 节流阀设置在限定在节气门体内的进气通道内。 马达和节流阀之间连接有速度或齿轮减速机构。 传感器检测电动机的旋转位置,即旋转角度,并具有可移动部分和固定感测部分。 可移动部分附接到马达的旋转轴,使得可动部分随着旋转轴旋转而旋转。 固定感测部分安装在节气门体上并设置在可动部分内。 通过检测电动机的旋转,计算部分可以精确地确定节流阀的打开程度。 传感器输出节流阀的开度。
