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： An object of the invention for a valve device having an inclined valve body is to suppress pressure loss at a valve opened condition to a smaller amount. The valve body is composed of a disc shaped valve member for closing a fluid passage, a first supporting portion provided at an outer periphery of the valve member and connected to a first shaft member, and a second supporting portion provided at another outer periphery of the valve member and connected to a second shaft member. The valve body is formed of a press-molded metal plate and forms a Z-shape when viewed in a direction parallel to a surface of the valve member.

摘要： A fluid control solenoid valve includes a fluid passage having a valve seat therein. The solenoid valve further includes a bellows having a valve element and a retractable bellows portion continuous with the valve element. The valve element opens the fluid passage when lifted from the valve seat, and closes the fluid passage when seated onto the valve seat. A first spring urges the valve element in a valve lifting direction away from the valve seat, while a second spring urges the valve element in a valve seating direction toward the valve seat. An electromagnetic actuator is further provided for moving the valve element in the valve lifting direction, when energized. The first spring is interposed between an adjusting screw and the valve element. The adjusting screw is arranged to be extended at a high temperature so as to increase a biasing force of the first spring urging the valve element in the valve lifting direction. This prevents a sealing load, which is applied to the valve element to cause it to be seated onto the valve seat, from increasing. Increase in sealing load would be otherwise caused due to thermal expansion of the bellows portion at the high temperature.

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.
