Claims

[Claim for Utility Model Registration] An intake system for an engine in which a rotary timing valve is provided in the intake passage of the engine, and the rotary timing valve is rotationally driven by the engine output shaft via a winding intermediate node to set the opening timing of the intake passage. In the rotary valve, the rotary valve includes a casing having an inlet and an outlet for intake air, and a rotor that is rotatably housed in the casing and communicates with and shuts off the inlet and the outlet according to the rotation of the casing. and a rotating shaft, one end of which is integrated with the rotor and the other end of which is linked to the winding intermediate joint; the casing includes a bearing casing located on the other end side of the rotating shaft; A main body casing housing a rotor is configured separately from each other, and the rotating shaft is supported by the bearing casing via a plurality of bearings arranged in parallel in the axial direction of the rotating shaft. Characteristic engine intake system.
