发明名称 Throttles
摘要 A throttle may include a throttle gear 5 is fastened to a throttle shaft 2. A relief lever 9 is pivotally mounted on the throttle shaft 2. A return spring 11 is adapted to urge the relief lever 9 in a valve closing direction with respect to a throttle body 1. A first contact means 20a is provided on the throttle body 1 and the relief lever 9 and the throttle body 1 contacts the relief lever 9 when the relief lever 9 pivots to a predetermined pivot position B in the valve closing direction. A relief spring 10 is adapted to urge the throttle gear 5 in a valve opening direction with respect to the relief lever 9. A second contact means 20b is provided on the throttle gear 5 and the relief lever 9 and the relief lever 9 contacts the throttle gear 5 when the throttle gear 5 pivots to the predetermined pivot position B in the valve opening direction. The predetermined pivot position B is preferably an initial or standby throttle valve position. The contact positions 20A, 20B of the contact means 20a, 20b are located within or to one side of a plane P that is perpendicular to the rotational axis L of the throttle shaft 2. Plane P preferably includes a position 20C in which the biasing force of the return spring 11 acts on the relief lever 9.
