摘要： In an electronically controlled throttle apparatus, a coil spring is shaped to extend from a U-shaped hook portion which is a joint between a first spring portion having a returning function and a second spring portion having an opening function to the other end of the second spring portion. A coating of a lubricant is provided on a sliding contact area between the inside circumferential surface of the coil spring and the outside circumferential surface of the second spring inside circumferential guide. Thus, the sliding resistance in relative motion between the coil spring and the second spring inside circumferential guide can be significantly reduced.

摘要： In a gear case of a throttle body, a valve gear is fixed to one end of a throttle shaft, an intermediate reduction gear is rotatable around an intermediate shaft, a pinion gear is fixed to a motor shaft of a drive motor, and a full close position stopper is provided for defining the full close position of a throttle valve. Those are provided all in alignment with the longitudinal centerline of the gear case. For car models where the throttle body bore inside diameter is identical but the rotation direction of the drive motor differs, only some components in the gear case need be replaced and the other components in the gear case can be used as common components.

摘要： A throttle device which prevents the entry of foreign compounds into a slidable contact portion between a brush and a commutator is provided to prevent the malfunctioning of a motor. A first shielding portion is integrally formed in a brush holder, which is attached to a yoke of a motor for holding a brush. The plate-shaped first shielding portion covers the vicinity of the yoke in the outer periphery of the yoke. Accordingly, the first shielding portion covers a gap left between the yoke and the brush holder, and a slidable contact portion between a commutator and the brush on a throttle gear side. Therefore, the first shielding portion prevents a foreign compound, generated in an engagement portion between the throttle gear and a reduction gear and falling onto a motor, from moving to the slidable contact portion, so that it is possible to prevent poor contact between the commutator and the brush.

摘要： In a low-pressure EGR system, a mechanical stopper limits a rotation range of a low-pressure EGR regulating valve at a limit opening degree of the low-pressure EGR regulating valve on its fully-open side and outside an EGR amount adjustment opening degree range of the low-pressure EGR regulating valve. After an engine is stopped, a failure detection unit rotates the low-pressure EGR regulating valve to its fully-open position to such an extent that rotation of a linking device is prevented by the mechanical stopper, and is configured to determine that a failure has occurred when an opening degree of the low-pressure EGR regulating valve detected by a low-pressure EGR opening sensor is different from the limit opening degree of the low-pressure EGR regulating valve.

摘要： When a failure occurs in synchronizing mechanism, an intake air throttle valve is rotated in a direction that is opposite from a normal operational time valve closing direction, so that an arm of a driven plate contacts a throttle valve side stopper to stop rotation of the intake air throttle valve. Thereafter, when a low pressure EGR valve is rotated from a full close position to a full open position, an EGR valve side stopper contacts the arm of the driven plate to stop the low pressure EGR valve. A rotational angle of the EGR valve is sensed with a sensor and is outputted to an ECU. The ECU determines that a failure mode is set when a valve angle sensed with the sensor coincides with a rotation stop position of the EGR valve.
摘要翻译：当同步机构发生故障时，进气节气门在与正常操作时间阀关闭方向相反的方向上旋转，从而驱动板的臂接触节流阀侧挡块以停止进气口的旋转空气节流阀。此后，当低压EGR阀从完全关闭位置旋转到完全打开位置时，EGR阀侧止动器接触从动板的臂以停止低压EGR阀。用传感器检测EGR阀的旋转角度，并将其输出到ECU。当用传感器检测到的阀角与EGR阀的旋转停止位置一致时，ECU确定故障模式被设定。

摘要： A converting mechanism is provided between an EGR control valve driven by an actuator and an intake-air valve for generating negative pressure, so that the intake-air valve is also driven by the actuator. The converting mechanism has a cam plate rotated together with the EGR control valve and an arm rotated together with the intake-air valve. A cam groove formed in the cam plate is engaged with a driving pin of the arm. The intake-air valve is held at its maximum valve opening position, when the EGR control valve is rotated in a first angular range, while the intake-air valve is rotated from the valve opening position to a maximum valve closing position when the EGR control valve is rotated in a second angular range.
