Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rotary valve device for exhaust gas recirculation capable of fully utilizing the EGR and of simplifying structure or control thereof, even used in a multicylinder engine. SOLUTION: A rotary valve device for an exhaust gas recirculation 20 includes a rotary valve for air intake 24 and a rotary valve for exhaust gas recirculation 25 which are disposed along an arrangement of a plurality of cylinders of an engine 1. Both of the rotary valves 24, 25 are cylindrical. An internal space of the rotary valve for air intake 24 is an intake air circulation part 24A in which a new intake air circulates. An internal space of the rotary valve for exhaust gas recirculation 25 is an exhaust gas circulation part 25A in which an exhaust gas circulates. COPYRIGHT: (C)2010,JPO&INPIT
