ABSTRACT:
A vane support ring is mounted within a housing to rotate about its axis and support vanes which pivot about diameters of the vane support ring and divide the interior of the housing into two chambers. Drive shafts, pivotally attached to the vanes, extend through drive shaft apertures formed through the housing to coordinate pivotation of the vanes to rotation of the vane support ring so that the two chambers increase and decrease in volume with rotation of the vane support ring. Gases are introduced into the chambers via an inlet port and discharged from the chambers via an exhaust port that are opened and closed in coordination with vane support ring rotation by poppet valves and a cam ring geared to the vane support ring and extending about the poppet valves or, alternatively, by a slotted valve ring extending circularly about the housing and geared to the vane support ring. A spark plug or fuel injector mounted on the housing provides a combusting fuel in each chamber at minimum chamber volume.
