Abstract

PURPOSE: To improve efficiency of a valve device for cost reduction by rotating a rotor provided on the side with an intake port and exhaust port and on the circumference with two valve holes and formed inside with an intake chamber and exhaust chamber.
CONSTITUTION: A rotor 2 is rotated at a half rotational frequency of a crankshaft by a shaft 9 in a housing 1 mounted on a cylinder head portion of an engine. The rotor 2 is formed respectively on the side with an intake port 3B corresponding to an intake pipe 3 and intake port 3A, on the opposite side with an exhaust port 4B corresponding to an exhaust port 4A and an exhaust pipe 4 and on the circumference with two valve holes 5 corresponding to a valve hole 6. The rotor 2 is formed inside with an intake chamber 7 and exhaust chamber 8, and the intake chamber 7 is provided with a fan 10. Thus, by providing a rotary valve system of a valve device, efficiency of the valve device can be improved while the cost can be reduced.
