Fluid Motor Is Rotary Type Patents (Class 60/623)
  • Patent number: 8646274
    Abstract: The present invention provides for a toroidal motor comprising a centrally located output shaft, a circular plate centrally and transversely affixed to the output shaft, a toroidal cylinder located in the same plane as and to the outside edge of the circular plate, pistons affixed to the outside edge of the circular plate and residing in the toroidal cylinder. A circular timing track may be used to time the action of a knife gate assembly which may be configured to induce a camming action in the knife gate assembly, rotating the knife gate into the toroidal cylinder, blocking the cylinder just behind a passing piston. Pressurized fluid may be introduced between the knife gate and the rear of the immediate downstream piston to cause a differential pressure to propel the piston through the toroidal cylinder.

  • Patent number: 8596068
    Abstract: An air aspirated hybrid heat pump and heat engine system (20) for selectively heating and cooling a space (22) having an flow path (24) including a compressor (76), a heat exchanger (32), an expander (78), and a generator (68). A combustion chamber (62) is in the flow path (24) for combusting a fuel in the air during a high heating mode. The heat exchanger (32) dissipates the heat from the air, and the expander (78) depressurizes the air while powering the generator (68). Also included is a positive displacement rotating vane-type device (36) having a stator housing (38) extending between longitudinal ends (40). A compression chamber inlet (52) and an expansion chamber outlet (58) are located on opposite longitudinal ends (40) of the stator housing (38) to be in simultaneous communication with the same chamber (48, 50)). A fluid enters the device through the compression chamber inlet (52) and pushes fluid out of the expansion chamber outlet (58).

  • Publication number: 20120304643
    Abstract: A waste heat recovery mechanism and a waste heat recovery apparatus generate electricity even when an expander, which is coupled to a combustion engine outputting rotational drive force, is locked. The waste heat recovery mechanism includes an alternator having a rotary shaft, which is coupled to and driven to rotate by a combustion engine, and an expander having an output shaft, which is coupled to the rotary shaft of the alternator. The output shaft applies a rotational drive force to the rotary shaft, thereby assisting rotation of the rotary shaft. A torque limiter is located between the rotary shaft of the alternator and the output shaft of the expander.

  • Publication number: 20100313562
    Abstract: Disclosed is a process for recovery power from an FCC product. Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors.

  • Publication number: 20090277173
    Abstract: A waste heat recovery system for use with an engine. The waste heat recovery system receives heat input from both an exhaust gas recovery system and exhaust gas streams. The system includes a first loop and a second loop. The first loop is configured to receive heat from both the exhaust gas recovery system and the exhaust system as necessary. The second loop receives heat from the first loop and the exhaust gas recovery system. The second loop converts the heat energy into electrical energy through the use of a turbine.

  • Publication number: 20080223040
    Abstract: A supercharged internal combustion engine of a motor vehicle has a cooling circuit, in which a working medium is recycled, which is conveyed at least partially in a vaporous or gaseous physical state. At least one expander unit is provided which is operatively connected with an output shaft of the internal combustion engine via a power train. Via a conversion of energy contained in the at least partially vaporous or gaseous working medium in the expander unit, an output shaft of the expander unit is moveable. The expander unit is embodied as a two-cycle reciprocating engine, which is operatively connected directly or indirectly via the power train with the output shaft of the internal combustion engine.

  • Publication number: 20080022684
    Abstract: A segmented heat exchanger system for transferring heat energy from an exhaust fluid to a working fluid. The heat exchanger system may include a first heat exchanger for receiving incoming working fluid and the exhaust fluid. The working fluid and exhaust fluid may travel through at least a portion of the first heat exchanger in a parallel flow configuration. In addition, the heat exchanger system may include a second heat exchanger for receiving working fluid from the first heat exchanger and exhaust fluid from a third heat exchanger. The working fluid and exhaust fluid may travel through at least a portion of the second heat exchanger in a counter flow configuration. Furthermore, the heat exchanger system may include a third heat exchanger for receiving working fluid from the second heat exchanger and exhaust fluid from the first heat exchanger. The working fluid and exhaust fluid may travel through at least a portion of the third heat exchanger in a parallel flow configuration.

  • Patent number: 5806315
    Abstract: An engine comprises a rotary unit (1) and a reciprocating unit (3) coupled to a common drive (7). A first rotary unit (1) provides the induction phase of the 4-stroke cycle and passes air to the reciprocating unit for the compression and combustion phases. The exhaust gases are passed to a second rotary unit (5) having an afterburner for the exhaust phase. Alternatively, two rotary units and two reciprocating units each having two pistons may be arranged alternately. The invention may also be utilized for improved 2-stroke engines making one power pulse per stroke.
