イドルスピードコントロールバルブ。An upstream passage branching from the intake passage upstream of the intake throttle valve and a downstream passage leading to the intake passage downstream of the intake throttle valve are connected through an opening provided in the peripheral wall of the slider housing, and one of the downstream passages A slider is fitted into a slider housing that is movable in the axial direction and is screwed onto a worm shaft that is rotationally driven by a stepping motor, thereby controlling the sliding of the slider as the stepping motor rotates. In the idle speed control valve, the opening degree of the opening formed in the slider housing is increased or decreased, thereby controlling the flow rate of air that is supplied bypassing the intake valve, thereby controlling the idle rotation speed of the engine. , the inner circumferential passage of the slider housing in which the downstream passage is held in communication, the space at the back of the slider that faces the slider with the slider in between, and the upstream passage held in communication with the outer circumferential passage of the slider housing via a balance passage; An idle speed control valve characterized in that it communicates with the idle speed control valve.
