摘要： PROBLEM TO BE SOLVED: To provide an intake device of an internal combustion engine reducing emission and improving fuel economy by efficiently introducing air to be sucked into an internal combustion engine into a combustion chamber.
SOLUTION: A first control valve 13 is rotated and driven with one internal wall 11 side of an intake pipe 30 of the internal combustion engine 1 as a center. A second control valve 14 is rotated and driven with the other inner wall 111 side of the intake pipe 30 as a center. The first control valve 13 and the second control valve 14 are oppositely provided in an intake passage 311 and cooperatively reduce cross-sectional area of the intake passage 311.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device in which the structure of a passage for a working fluid into a control valve is simplified.
SOLUTION: The spool 101 of the control valve 100 opens and closes an advance-angle passage 86 by a force applied thereto from the hydraulic oil supplied from an advance-angle pilot oil passage 103 and the pressing force of an elastic member 100 kept in balance with each other. Therefore, since the oil passage for introducing a hydraulic pressure driving the spool 101 is only an advance-angle pilot oil passage 103, the oil passage structure of the control valve 100 can be simplified, and the structure of the device can be simplified. The elastic member 110 is fitted to the end of the spool 101 in the axial direction of a vane rotor 21. Consequently, even if a centrifugal force is produced according to the rotation of the vane rotor 21, it does not act on the spool 101 and the elastic member 110.
