FIELD: engines and pumps. SUBSTANCE: proposed engine comprises outer rotor to create outer liquid ring and inner rotor to create inner liquid ring that incorporates suction chamber and combustion chamber. Rotors rotational axes are located off center, while rotors run in one direction. When suction space stays in outer liquid ring low-pressure zone, it receives a portion of combustible mix. When said space displaces in high-pressure zone, said mix is forced into combustion chamber to be held by inner liquid ring. Ignition of compressed mix causes ejection of jet to start rotor running. EFFECT: reduced number of assembly units and parts. 1 dwg
The invention relates to the class of hydro jet engines, which are used in water transport. As the working fluid for the specified motors used outboard water is a limited amount which enters into the working chamber of the engine, and then under the influence of the pressure pulse gas or vapor-gas medium flows out into the surrounding space, creating a jet thrust. Known FLOW hydro jet MARINE ENGINE (USSR author's certificate No. 1068337, CL VN 11/02, 30.01.81)containing the switching chamber with a spring-loaded flap that allows you to direct incoming flow sea water alternately in each of the two working chambers, creating conditions for compression and ignition of the combustible mixture with a subsequent release of a jet of the cone of the engine. The disadvantages of this engine should be attributed to the relatively low compression ratio of the combustible mixture. Also known (USSR author's certificate No. 1720927 A1, CL VN 11/02, 11/14, 14.03.90) UNIFLOW hydro jet MARINE ENGINE ROW containing the device for filling the working rolls of the sea water in the form of a centrifugal pump with electric drive, a device for filling the combustion chamber with compressed air in the form of a piston compressor, fuel pump of a high pressure, and is also the feeder sparks, kinematically connected with the shaft drive. The disadvantages of this engine should include the need to integrate into the workflow of additional units, supplied from foreign sources of energy and do not use the kinetic energy of the jet stream. The proposed solution aims to eliminate the above disadvantages of the prototypes and the expansion of the scope hydro jet engines. To achieve this objective, it is suggested such a device working bodies of the engine, which allows you to change in a wide range of the compression ratio of the combustible mixture, which increases the possibility of choice of energy and provides a variety of options for the use of engines with liquid piston. The drawing shows a schematic representation of the hydro jet device of the engine. The outer rotor 1 rotates on the fixed pin 14 of the engine block, creating a liquid ring 2 by means of the vessel, the shape and dimensions which ensure the continuity of the radius of the cylindrical free surface of the liquid in the surrounding gaseous environment, and provide for placement of the inner rotor 3 in the external liquid ring 2. The inner rotor 3 that is designed to create internal liquid ring 4 rotates in an eccentric Rast is CCA stationary axle 14. On the periphery of the rotor 3 are working chambers, each of which comprises a vessel divided by a partition with injection valve 5 into the cavity 6 and the suction cavity of the combustion chamber 9. The cavity is provided with a suction channel for supplying fresh gas mixture 7 and the intake valve 8. In the cavity combustion includes forming the jet stream channel without valve 12, which is free to receive the working fluid from the internal liquid ring 4 and the exhaust valve 11 is opened, the gaseous remnants of the combustion products come into the exhaust channel 10. The magnitude of the eccentricity and the overall radial dimensions of the inner rotor 3 provide such an arrangement in the outer liquid-ring to the peripheral edge of the suction cavities 6 does not extend beyond the rings volume 2. To maintain a constant level of the free surface of the liquid in each liquid rings there is a device constant supply of fluid from an external source. Excess fluid and gaseous products of combustion are discharged through the channel 15 on the outer rotor 1, with the supply of energy, which they have converted into kinetic energy of the jet stream generated by the output section of the channel so that the reactive force contributed to the rotor 1. The direction of the treatment rotor 1 and 3 coincide. The eccentric position of the rotor 3 in a liquid ring 2 of the rotor 1 at their mutual rotation causes the cavity suction 6 continuously moves in the ring 2 from the zone of high pressure working fluid in the area of low pressure and Vice versa. The working cycle of the engine starts with the receipt of a portion of the fresh combustible mixture into the cavity of the suction. When sufficient pressure opens the inlet valve 8, and channel 7 fresh combustible mixture flows into the cavity suction 6 with a closed discharge valve 5. The suction process continues until the beginning of the movement of the cavity 6 in the zone of high pressure. The valve 8 is closed, the process of compression of the combustible mixture. At a sufficiently high pressure compression opens the discharge valve 5 and start moving the mixture into the cavity of the combustion chamber 9 until its complete exclusion from the suction cavities 6. The discharge valve 5 is closed, the mixture is held in compressed condition by the pressure of the liquid column in the channel 12. After closing the valve 5 is to ignite the compressed mixture, followed by a sharp rise in pressure and temperature with subsequent displacement of the working fluid and the vapor-gas mixture in the channel 12 forming the jet stream, which causes the rotation of the rotor 3. From channel 12 jet of working fluid and the vapor-gas mixture which falls on the blades stationary reactor 13, where there is a change in the magnitude and direction of the jet velocity, after which the working fluid returns to the ring 4 or the ring 2 and the gas-vapor mixture enters the channel 15. After working liquid and gaseous products of combustion from the cavity 9 leads to a fall in pressure in it, which gives the opportunity to open the exhaust valve 11. The remains of the combustion products move in the exhaust channel 10 working liquid flowing from the liquid ring 4 through the channel 12 in the cavity of the combustion chamber 9 until full replacement of the gas, after which the exhaust valve 11 is closed and a new working cycle. The proposed device allows you to change the compression ratio of the combustible mixture in a fairly wide range by changing the frequency of rotation of the rotors and the use of working fluids with different density values. The closed circulation of the working fluid gives the opportunity to expand the scope hydro jet engines. Hydro jet engine that uses liquid piston to compress the combustible mixture in the working chamber and recycle energy emitted from the ignition of the compressed fuel-air mixture, characterized in that it contains the outer rotor, designed to create an external liquid ring with a free surface in an ambient gas environment using continuously what about the rotation of the vessel, equipped with a channel for directing liquid and gas mixture to maintain a constant level of the free surface of the liquid ring and utilization of the energy content of the exhaust products; the inner rotor, placed eccentrically in the outer liquid ring, designed to create internal liquid ring with a free surface in an ambient gas environment containing a working camera, each of which comprises a vessel divided by a partition with the discharge valve in the cavity of the suction supplied by the channel with suction valve for supplying fresh combustible mixture, and the cavity combustion is supplied by a channel with the exhaust valve, and do not have a valve channel, a column of fluid which keeps the fresh combustible mixture is compressed and after ignition is converted in the jet stream, which creates a torque on the shaft of the inner rotor; a stationary vane system located on the motor housing and is used to change the magnitude and direction of velocity of the jet stream.
