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： 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： A PCV valve is arranged in an outflow passage. An ECU controls rotation of a motor such that an opening degree of the PCV valve increases in response to an increase in an opening degree of a throttle valve. The outflow passage connects an interior of a head cover of an engine to a portion of an intake air passage located on a downstream side of the throttle valve. The outflow passage recirculates blow-by gas leaked from a combustion chamber into an interior of a crankcase to the portion of the intake air passage located on the downstream side of the throttle valve. An inflow passage connects the interior of the head cover to a portion of the intake air passage located on an upstream side of the throttle valve. The inflow passage conducts intake air from the intake air passage to the interior of the head cover.
