Claims

[Scope of utility model registration request]

In a helical intake port configured with a spiral part formed in the intake valve layer and an inlet passage part connected tangentially to the spiral part and extending almost straight, the spiral part is branched from the manual inlet passage part. A hollow sleeve is provided with a bis-operated hydraulic chamber by forming a branch passage in the cylinder head that communicates with the spiral end of the part, and further forming an opening/closing valve insertion hole extending across the branch passage in the cylinder head. is inserted into the opening/closing valve insertion hole, and a valve body that is connected to the piston and controls the opening and closing of the branch passage is slidably inserted into the hollow sleeve, and a longitudinal section of the valve body is inserted on the outer circumferential surface of the valve body. A flow path control device for a helical intake port that has a spiral groove that extends over the entire length.
