Claims

[Scope of utility model registration request]

A spiral portion formed in the intake valve barrel, an inlet passageway connected tangentially to the spiral portion and extending substantially straight, and a branch branching from the inlet passageway and communicating with a spiral end portion of the spiral portion. A rotary valve for controlling the opening and closing of the branch passage is disposed within the branch passage, and the tip of an arm attached to the valve shaft of the rotary valve is connected to an actuator. In an internal combustion engine in which the spiral directions of the spiral portions of at least one pair of cylinders are opposite to each other, the arms of the rotary valves provided in the pair of cylinders extend in opposite directions with respect to a line connecting each rotary valve. A first connecting rod and a second connecting rod are arranged to extend substantially parallel to each other on both sides of the line connecting the rotary valve, and the intermediate portion of the first connecting rod is pivotally connected to the tip of one of the arms. At the same time, one end of the second connecting rond is pivotally connected to the tip of the other arm, further, one end of the first connecting rond is connected to an actuator, and the other end of the first connecting rond is formed of a pin and an elongated hole. An intake control device for an internal combustion engine connected to the other end of the second connecting rod via a loose connecting mechanism.
