Claims

[Scope of utility model registration request]

A sliding rotary intake control valve disposed in an engine intake passage so as to be rotatable about a rotation axis substantially orthogonal to the axis of the intake passage and slidable in the direction of the rotation axis, and one end of the intake control valve. an actuator connected via an actuating rod to slide the intake control valve in the direction of the rotational axis; the other end of the intake control valve is connected to a rotational shaft rotationally driven by the engine, and the actuator The valve has a first portion having a valve opening that blocks intake air for a predetermined period of time after the intake valve is opened during the intake stroke according to the rotational angular position of the valve, and a contour that allows the intake passage to be opened at all times regardless of the rotational angular position. and a second part, and the intake control valve is moved by the actuator in accordance with the engine rotational speed into a first position where the first part is located within the intake passage and a second position where the second part is located within the intake passage. 2. An air intake control device for an internal combustion engine, wherein the actuating rod is supported by a slide bearing member that is slidable in the direction of the rotational axis.
