ジンの吸気装置。[Claims for Utility Model Registration] A rotary piston engine in which a polygonal rotor rotates planetarily within a casing consisting of a rotor housing having a trochoidal inner peripheral surface and side housings located on both sides of the rotor housing, A peripheral port that opens on the rotor side of the rotor housing and supplies intake air into the casing, and a side port that opens on the rotor side of the side housing and supplies intake air into the casing. A control valve is provided that closes when the intake air amount is high and opens when the intake air amount is high, so that the natural frequency related to the intake inertial supercharging effect on the peripheral port side is lower than the natural frequency related to the intake inertial supercharging effect on the side port side. An intake device for a rotary piston engine, characterized in that it is configured as follows.
