    Abstract: Implementations of the present invention comprise a rotor assembly for use in a rotary compressor. The rotor assembly includes a shaft, a pair of end plates, an input shaft, and a rotor. The rotor can be positioned between the pair of endplates. At least two of these components can be machined or formed as an integral unit, to increase the geometrical precision and integrity of the rotor assembly. For example, the rotor and input shaft can be formed integrally; alternatively, one of the endplates and the input shaft can be formed integrally. A pair of liners can be provided and positioned between the endplates and the rotor to increase sliding and/or sealing performance against other components of the rotary compressor, such as a gate positioned in a bore of the rotor.

  • Patent number: 8733317
    Abstract: A rotary engine has a rotor that has rockers pivoting in chambers. As each rocker pivots, it rotates an outer crankshaft. Each outer crankshaft has a spur gear that engages a stationary ring gear. Spur gear rotation causes the gears and the outer crankshafts to revolve around the ring gear. This cause the rotor to rotate. As the rotor rotates, successive chambers are positioned at the intake, compression, ignition, and exhaust positions. Igniting the fuel in the ignition position pushes the rocker inward to rotate the outer crankshaft associated with that rocker to cause the rotor to rotate.

  • Patent number: 7073477
    Abstract: A rotary engine is provided with solid vanes which extend through the rotor and engage opposing interior wall portions of the stator housing. A series of grooves in the interior wall permit the expanding exhaust gases to by-pass the minimal surface area of vanes proximate to the combustion chamber to engage the larger surface area of a vane which is protruding more significantly from the rotor. This robust rotary engine is preferably made of cast iron, having internal portions coated with ceramic so that it readily can operate at temperatures exceeding 850° F. The heat energy is utilized to obtain maximum productive work rather than being discarded as a waste product as is typical with most state of the art power plants, resulting in an efficiency rating exceeding 60%.

  • Patent number: 5302096
    Abstract: A rotary vane compressor includes two stator chambers allowing two compression strokes for each revolution of the rotor. The shape of the chamber walls is specifically designed through the use of a sine function to increase efficiency of breathing of the compressor by providing a larger initial starting volume which reduces to a smaller discharge volume. The invention further includes a vane guiding mechanism preventing the rotor vanes from falling into the bottom of their respective slots to prevent slamming of the vanes upon start-up of the compressor.

  • Patent number: 5277158
    Abstract: A three-piece housing enclosing a cavity has rotatably mounted therein a rotor having a plurality of slots, each slot supporting a vane. Each vane has a retention end guided in its revolution around the rotor by an internal, non-circular vane retention track. Two adjacent vanes define opposite sides of a combustion chamber, while the housing and the portion of the rotor between the adjacent vanes form the remaining surfaces of the combustion chamber. Each combustion chamber is rotated past an intake port, a diagonal plasma bleed-over groove, and an exhaust port to accomplish the phases of a combustion cycle. Fuel ignition is provided to more than one combustion chamber at a time by expanding gases passing through a plasma bleed-over groove and being formed into a vortex that ignites and churns the charge in a succeeding combustion chamber.

  • Patent number: 5069608
    Abstract: A vane pump delivers pasty materials, particularly sausage stuffing, for the purpose of filling doses of the stuffing into sausage cases. The flow of material into the pump chamber generally takes place by a stuffing device in the hopper and by the action of the vacuum to which the vane pump is exposed. The degree of filling and therefore the dosing accuracy is improved by providing a curved portion in the transition area between the inner wall of the cylindrical part of the cup-shaped pump casing and the base part of the latter receiving the pump rotor mounting.

  • Patent number: 4859163
    Abstract: The rotary machine, for example an air pump, has two rotors and vanes carried by the rotors within a housing, to pump fluid between an inlet and an outlet on opposite sides of the housing. The vanes are guided by tracks, so that the vanes are withdrawn flush with the rotor surfaces at a contact line between the rotors. In one embodiment, ends of the vanes are carried in carriers by means of bearing blocks. The carriers rotate at an average speed equal to that of the rotors, to reduce the movement of the ends of the vanes. The mechanism can be employed in a single rotor machine.

  • Patent number: 4465445
    Abstract: A pivoted vane rotary pump especially for pumping food-stuff and abrasive material comprises a split housing in which a hub is rotatable, with an annular channel formed between the outer periphery of the hub and the inner periphery of the housing. Pivoted vanes on the hub are rotatable about radial axes between a position in which they are crosswise of a transport portion of the channel between an intake and a discharge and a position in which they move edgewise in a restricted sealing portion of the channel between the discharge and the intake. The housing is lined with elastomeric plastic material which is vulcanized to metal housing parts of pumps for handling foodstuff or corrosive media, or is vulcanized to metal carrier plates removably secured to housing parts of pumps for handling abrasive media. The pump can be easily disassembled for cleaning and for servicing, including replacement of the plastic lining of pumps for abrasive media.

  • Patent number: 4033300
    Abstract: A rotary internal combustion engine comprising a generally cylindrical stator member having two pairs of sockets located in the periphery thereof, and a rotor member mounted to rotate about the stator member. Two pairs of opposing wedges are pivotally mounted at their vertices on the periphery of the stator member to pivot in and out of respective ones of the sockets as the rotor member is caused to rotate about the stator member. The rotor member has side walls and an interior peripheral wall which, in cooperation with the periphery of the stator member and the two pairs of pivotal wedges, define a combustion cavity and a compression cavity there between. The combustion cavity and compression cavity are disposed on opposite sides of the stator member adjacent the periphery thereof.

  • Patent number: 4020917
    Abstract: A vehicle has a primary drive pump in communication with driven pumps associated with each wheel for driving the vehicle as hydraulic fluid is ported to the wheel pumps through a by-pass valve. The pumps are similarly designed with each including a rotor co-axially mounted within a fixed stator defining an annular pump chamber when fluid entering an intake opening moves against gradually extending vanes provided on the rotor. The fluid exits through a discharge opening in the stator, and the vanes are designed to be fully retracted at a position between the openings and gradually extended so as to fully extend after moving beyond the intake opening. Also, the vanes gradually retract as they approach the discharge opening.
