Abstract
A turbine comprising a housing and a vane assembly rotatably mounted in the housing for rotation about the axis of a ring forming a portion of the vane assembly. Vanes are mounted on the ring to pivot about diameters of the ring and sealing surfaces are formed on the vanes to mate with the inner surface of the housing and thereby divide the interior of the housing into an inlet chamber and an outlet chamber. The chambers move about the ring axis as the ring rotates and expand and contract with pivotation of the vanes on the ring. Drive shafts pivotally attached to the vanes extend through the housing wall so that rotation of the vane assembly will cause rotation of the drive shafts. The drive shafts further relate the vane assembly rotation to pivotation of the vanes on the ring so that pivotation of the vanes caused by pressurizing the inlet chamber while exhausting the outlet chamber will rotate the vane assembly and drive shafts. Ports formed through the housing wall and slots formed through the ring wall to provide fluid communication to the inlet and outlet chambers are positioned to cause a reversal between the inlet and outlet chambers for a selected position of the vane assembly in the housing so that the vane assembly will always rotate in the same direction.
