Abstract
An oscillating engine having synchronized oppositely-rotating vaned rotors in adjacent arcuate chambers. Intake and exhaust openings for each chamber are located adjacent to each other near at least one of the extreme positions of oscillation of each respective rotor. A rotary valve member positioned adjacent both to the intake opening and the exhaust opening of each chamber is actuated intermittently by a chain and sprocket drive in timed relation with the rotor oscillation between positions where the valve alternately closes each intake and exhaust opening to positions where the valve alternately partially opens each intake and exhaust opening. The rotary valve includes angled first and second camming surfaces, and a camming member resiliently biased against the valve member forms an acute angle with the first camming surface when the exhaust opening is partially open and forms an acute angle with the second camming surface when the intake opening is partially open to further rotate the valve to fully open exhaust and fully open intake positions, respectively. The design is suitable for either pressurized compressible fluid or internal combustion engine application.
