Abstract
A rotary engine is provided with a rotary piston that is rotatively mounted within a housing. The rotary piston includes a surrounding circumferential edge that is provided with a series of distinct depressions formed therein. Formed in the housing outwardly of the rotary piston is a pair of valve housings with each valve housing including a rotary valve mounted therein. Each of the rotary valves are driven in time relationship to the rotary piston. As the rotary piston rotates within the housing, there is a series of chambers defined between respective depressions and the housing. Moreover, as the rotary piston and rotary valves rotate, they cooperate to form four separate chambers around the rotary piston, including combustion, exhaust, intake, and compression chambers. In the embodiment illustrated herein, for each revolution of the rotary piston, there are two compression, intake, exhaust and combustion cycles or phases.
