  • Engine airflow management system
    Patent number: 7213546
    Abstract: A rotary valve assembly for an internal combustion engine is herein disclosed. The rotary valve assembly comprises a valve body having a number of ports formed therethrough and a bore that intersects these ports such that a valve cylinder inserted into the bore may selectively occlude or open the ports of the valve body. Cutouts formed into the valve cylinder facilitate the opening of the ports as they are rotated into alignment with the ports of the valve body. The rotary valve assembly may be used as a throttle mechanism by sliding the valve cylinder longitudinally within the bore of the valve body so as to control the aspect of the cutouts or bores formed into the valve cylinder that is presented to the ports.
