介装されて吸気弁に対応した速度で回転駆動され
該燃焼室内への吸気タイミングを制御する吸気制
御用ロータリバルブにおいて、該通路枝部が該ロ
ータリバルブの前後で２つの通路部分に分割され
ていると共に、該ロータリバルブ内に該２つの通

を特徴とする、吸気制御用ロータリバルブ構造。 In an intake control rotary valve that is installed in a passage branch on each combustion chamber side of an intake passage of an engine and is driven to rotate at a speed corresponding to the intake valve, the intake control rotary valve controls the timing of intake air into the combustion chamber. The rotary valve is divided into two passage portions before and after the rotary valve, and two intake flow holes are formed in the rotary valve to intersect each other at right angles and to communicate with the two passage portions at the same time. A rotary valve structure for intake control.
