Patent ID: 8087394

Claim:
A dual-level combustion chamber system, comprising: a dual-level combustion chamber comprising first and second vertically-stacked combustion chambers; and a dual-level, two position valve operatively associated with said dual-level combustion chamber for controlling the ingress of an air/fuel mixture into said first and second combustion chambers and the egress of combustion products out from said first and second combustion chambers; wherein said dual-level valve comprises a single dual-level, two position rotary valve rotatably mounted upon said dual-level combustion chamber for movement between first OPENED and second CLOSED positions, a vertical partition, a semi-circular horizontally oriented plate disposed upon one side of said vertical partition so as to define and fluidically separate an inlet port, for permitting the ingress of the air/fuel mixture into said first combustion chamber, from an outlet port for permitting the egress of the combustion products out from said second combustion chamber, while an opposite side of said vertical partition defines a vertically oriented fluid passageway fluidically connecting said first and second combustion chambers, whereby when said dual-level rotary valve is disposed at said first OPENED position, an air/fuel mixture can enter said inlet port, traverse said first combustion chamber, traverse said vertically oriented fluid passageway, traverse said second combustion chamber, and exit said second combustion chamber through said outlet port so as to scavenge combustion products from said combustion chamber system which were generated during a combustion cycle, whereas when said dual-level rotary valve is disposed at said second CLOSED position, an air/fuel mixture is trapped within said first and second combustion chambers so as to be ready for a combustion cycle.
