    Abstract: A valve device has a valve that opens and closes a passage, and a cantilever bearing member rotatably supporting a rotating shaft of the valve. The cantilever bearing member has rolling-element bearings arranged in series in an axial direction of the rotating shaft. One of the rolling-element bearings located the closest to the passage has a rolling element, an inner race, an outer race and a seal portion. A space is defined between the inner race and the outer race to receive the rolling element. The seal portion made of rubber tightly seals the space on a side adjacent to the passage.

    Abstract: Provided is a resin bush capable of slidably supporting a shaft when the bush has been fitted in a housing; particularly, a resin bush suitable for use in an environment in which the effects of a difference in thermal expansion coefficients are likely to be prominent, such as a high-temperature environment, even when the housing and the shaft are made of a material such as a metal that has a different thermal expansion coefficient from that of the resin bush. In the resin bush (1), which is molded by extrusion molding, a slit (12) is formed from one axial end surface (11a) towards another axial end surface (11b). A recessed section (13) for a gate (a gate position), which is provided to the one axial end surface (11a), is provided in a position that is deviated from being symmetrical with the slit (12), at least with respect to a center axis O of a bush body (10). The resin used for the material of the bush (1) is a resin having excellent heat resistance and chemical resistance, such as PPS resin or a PEEK resin.

    Abstract: An EGR device has a housing defining an EGR passage through which an EGR gas flows; a shaft rotatably supported by the housing through a bearing; a valve body adjusting a flow passage area of the EGR passage by rotating along with the shaft; and an actuator connected to one end portion of the shaft to drive the shaft. The bearing has a first bearing supporting one end portion of the shaft and a second bearing supporting the other end portion of the shaft. Moreover, a sealing member preventing fluid from flowing into the actuator is disposed at one end portion of the shaft. The housing has the chamber which accommodates the second bearing and is isolated form the exterior. The second bearing is made of a PPS resin material to which a fluororesin material is added. Thus, the second bearing is not corroded even if exposed to an atmosphere of strong acid.

    Abstract: A valve device includes a valve, an actuator actuating the valve, a control unit controlling an opening degree of the valve, a return spring biasing the valve only in a valve-closing direction, and a mechanical stopper controlling a rotating limit of the valve in the valve-closing direction. The valve is defined to rotate on a plus side from the full-close position in a valve-opening direction and to rotate on a minus side from the full-close position in a direction opposite from the valve-opening direction. The mechanical stopper stops the valve at a stopper position which is set on the minus side from the full-close position, and a predetermined overshoot range is defined between the full-close position and the stopper position.
