    Abstract: A second rotor and a third rotor are accommodated in a first rotor. A fitting portion of the third rotor is located in an engagement hole of the second rotor to engage the third rotor with the second rotor. The third rotor is rotational about an axis, which is eccentric to an axis of the first rotor, to vary a relative rotational phase of the first rotor to the second rotor and to accelerate and decelerate rotation of the second rotor. When friction arises between the second rotor and the fitting portion, a frictional force acts in a direction to reduce a rotational moment acting on the third rotor. A friction coefficient between the second rotor and the fitting portion is greater than a friction coefficient between ferrous objects.

    Abstract: A plate within the valve pivots about a shaft to cause the plate to transition between an open position and a closed position within a bore passing through the housing of the valve. The plate has a perimeter seal thereon which abuts against a tapering seat of the bore when the throttle plate is in a closed orientation. The seal has a curving form over a recess and an energy source, such as the toroidal spring in the recess, to energize the seal and allow it to maintain secure contact against the seat. The shaft is offset from the centerline of the bore and the plate is mounted to the shaft at a location offset from the center point of the plate, so that rotation of the plate causes the plate to swing somewhat into a closed position, minimizing abrasive contact between the seat and seal during closing.
