A vane cell machine includes a housing, rotor, curved ring, spring, and pressure piece. The rotor is configured to rotate about a rotation axis and includes a plurality of plate-like wings that are radially displaceable. The curved ring surrounds the rotor and delimits a movement path of the wings. Each pair of adjacent plate-like wings delimits a corresponding operating chamber. The housing surrounds and enables displacement of the curved ring. The spring is positioned between the curved ring and the housing, is pretensioned, and is configured to load the curved ring. The pressure piece is positioned between the spring and the curved ring, and sealingly abuts the housing and the curved ring so as to delimit a first and second pressure chamber from each other. The housing and the curved ring further delimit the first and second pressure chambers.

An axial vane rotary device (14) includes a stator (16)with a cylindrical internal chamber (34) defined an annular outer wall (40) and two side walls (36, 38) of the stator. Each side wall has an annular cam surface (42, 44). A rotor (54) is rotatably mounted within the chamber. The rotor has an annular outer wall (66) and a plurality of angularly spaced-apart, axially extending slots (64) extending therethrough. A vane (68) is slidably received in each slot. The vanes reciprocate axially and alternatively expand and compress spaces between adjacent vanes and the cam surfaces as the rotor rotates. The cam surfaces have alternating first portions (92) and second portions (90). The second portions are further from the rotor than the second portions. The first portions of one said cam surface are aligned with second portions of another said cam surface. The slots extend radially outwards on the rotor to the annular outer wall thereof. The outer edge of each vane slidably engages the annular outer wall of the stator. The outer wall of the stator may have a guide cam (96) and the vanes may each have a follower (98) received by the guide cam. The guide cam is shaped to cause the vanes to reciprocate axially with respect to the rotor as the rotor rotates. Each of the vanes may have resiliently biased first seals (110, 112) extending along the inner edge (106) and second seals (134) along side edges (70, 72) thereof.

Rotary internal combustion engine of axial sliding vane type has sinusoidal shaped side walls with compensation of the mass forces allowing nearly friction-free and high speed operation with sufficient compression ratio. High power output is believed to make the invention comparable to the well-known Wankel engine.The various designs of the rotary machines can also be used as fluid pumps or fluid-operated motors.
摘要:
A positive displacement rotary apparatus comprising a rotor having opposed faces on opposite sides thereof; a housing around the rotor and having opposed internal side walls facing the opposed faces of the rotor; and a plurality of circumferentially spaced vane means extending slidingly through the rotor in a direction substantially parallel to the rotational axis thereof and disposed radially outwardly from the axis of rotation of the rotor on substantially the same radius. An annular recess which periodically varies in depth and width over its length is formed in each of said internal side walls of the housing concentrically with respect to the axis of rotation of the rotor. The annular recesses slidingly receive opposite ends of the sliding vane means, and the bottoms of the recesses are equidistantly spaced from each other at all aligned points over the length of the recesses as measured along any one vane means having its opposite ends in the recesses. Means is provided on the rotor for sealing a portion of each recess between adjacent vane means to form a chamber varying in volume as the rotor is rotated and the ends of the vane means sweep around the annular recesses. Spaced ports are provided through the housing in communication with spaced locations along the recesses to provide for timed injection and exhaustion of fluids from the chambers of varying volume defined between vane means.
摘要:
A rotary internal combustion engine wherein the compression and the power functions are produced by a single rotor with the compression function being achieved by means of vanes that move longitudinally of the axis of rotation of the rotor and cooperate with complimentary recesses and with the power function being achieved by means of members that move laterally of said axis of rotation and cooperate with the periphery of the stator.

The invention relates to positive-displacement fluid machines which may be used as pumps, compressors or motors.The machine includes a piston integral with the stator and engaged in an annular cylinder formed in the rotor. Movable partitions slide in longitudinal grooves in the rotor and create fluid-work chambers in the cylinder. Cams for actuating the partitions determine, between the rotor and the stator, periodically-variable volumetric spaces filled with fluid under pressure suitable for providing an assisted control for the displacement of the partitions.
摘要:
A fluid pumping vane including a body member having arcuate end surfaces in close proximity to surfaces of a pump housing defining a fluid chamber. The vane body member, having front and rear surfaces, also includes resilient lips terminating in free ends, the lips overlying the arcuate surfaces of the body member and being inherently biased into engagement with the housing surfaces to provide a tight seal. In preferred form, the body member can be composed of aluminum, graphite, bakelite, or similar material, while the sealing lips are composed of a low friction resilient plastic material such as polytetrafluoroethylene or any other low friction fluoropolymer. The sealing lips extend toward the front surface of the vane body so that high pressure gases enter the area between the arcuate end surfaces of the body and the lips and further urge the lips into engagement with the housing surfaces. The plastic material sealing lips can be integral with the vane body member, they can be attached to a surface of the vane body member by a polyimide type adhesive or they can be formed to include a tongue portion received in a mating retaining groove in the body member.
