Abstract:
1. An idle air control apparatus in a multiple throttle body comprising: a first throttle body provided with a first intake passage so as to pass through an inner portion thereof, and structured such that said first intake passage is opened and closed by a first throttle valve; a second throttle body provided with a second intake passage so as to pass through an inner portion thereof, and structured such that said second intake passage is opened and closed by a second throttle valve; said first throttle body and said second throttle body being arranged in adjacent to each other; and idle air controlled by a single plunger valve actuated by a valve body driving mechanism being supplied to a downstream side intake passage from a first throttle valve via a first bypass air passage and supplied to a downstream side intake passage from a second throttle valve via a second bypass air passage, wherein the idle air control apparatus is provided with a first air control hole and a second air control hole which are open to an upper side wall of a valve body slidable hole provided in a control apparatus main body, and is provided with a first air hole and a second air hole which are open to a lower side wall, and said first air control hole and the second air control hole are arranged movably within the valve body slidable hole, and are controlled so as to be opened and closed by the plunger valve actuated by the valve body driving mechanism, wherein said idle air control apparatus is fixedly arranged so as to be held between one side wall surface forming a facing surface to the first throttle body, and another side wall surface forming a facing surface to the second throttle body, the one side wall surface and the other side wall surface being adjacent to each other, wherein the first bypass air passage communicating with the intake passage at the downstream side of the first throttle valve is connected with the first air control hole via the one side wall surface of the first throttle body, and the second bypass air passage communicating with the intake passage at the downstream side of the second throttle valve is connected with the second air control hole via the other side wall surface of the second throttle body, and wherein a first air introduction path communicating with the intake passage at the upstream side of the first throttle valve is connected with the first air hole via the one side wall surface of the first throttle body, and a second air introduction path communicating with the intake passage at the upstream side of the second throttle valve is connected with the second air hole via the other side wall surface of the second throttle body.
