ABSTRACT:
An oscillatory fluid powered motor includes a cylindrical body closed at its opposite ends by head members to define a chamber. Each head member has a central opening in aligned relationship with the longitudinal axis of the cylindrical body for receiving the opposite ends of a shaft. At least one vane is structurally associated with the shaft for rotation therewith, and extends radially of the cylindrical housing from the shaft. At least one stationary stator is attached to the interior wall of the cylindrical housing and extends radially of the housing. The cylinder heads include a bearing surface surrounding the central openings, and a ring seal concentrically disposed with and radially spaced from the central openings. The vane has a peripheral seal which sealingly contacts the bearing surface of each cylinder head, the interior wall surface of the cylindrical body and a portion of each ring seal. Similarly, the stator has a peripheral seal which sealingly contacts the bearing surface of each cylinder head, the peripheral surface of the shaft, and a portion of each ring seal.
