The rotary engine comprises a body 1, two conical rotors 2 whose surfaces are in contact, on which the blades of the motor 3 and the compressor 4 are rigidly fixed and there are cavities 5, 6, into which the blades enter during rotation, the conical synchronizing gears 7 included in the gearing, On the shafts of the rotors 8 in a separate common housing 9. The enclosed space within the housing, between the walls of the housing 1 and the rotors 2, forms the working cavity of the motor 10 and the compressor 11 separated by the inner wall 12, each of the cavities common to both rotors. The blades 3,4 tightly overlap the cross sections of the working cavities 10, 11 and the cross-sections of the depressions 5, 6. In the end wall of the rotor 2 and in the end wall of the body 1, holes 13 and 14 are respectively made, to the holes 13 aligned when they move with holes 14 made In the engine casing 1, the discharge pipes 15 of the compressor are supplied, the rotors 2 have cavities 16, in the cavities 16 of the motor rotors channels 17 are made, and in the side walls there are windows 18, labyrinth seals 19 are provided in the end walls of the casing, the rotor and on the vanes, and The lateral walls of the rotors - the sealing projections and valleys that are not included in the gearing.
OPERATION OF THE ROTARY ENGINE CONCLUDES IN THE FOLLOWING
The conical rotors 2 rotate in opposite directions, the side walls of the rotors roll one on the other without slipping, and the motor blades 3 move in the working cavity of the motor 10. The equality of the angular rotational speeds of the rotors is provided by synchronizing gears 7. When the engine blades 3 come out of the depressions 5 Rotors 2 and overlapping them with the section of the working cavity 10, the latter is divided by the blades into two parts: the inner one, closed between the blades, the body 1 and the rotors 2 forming the combustion chamber, and the outer space is the working space. In this case, the combustion chamber and the working space are common for both rotors 2, and one of the walls of the combustion chamber is the blades of the engine 3. Due to the increase of the inter-port space in the combustion chamber, a vacuum is created. Compressed air and fuel are supplied to the rarefaction zone. The resulting fuel mixture ignites from the spark plug or from compression. The working medium formed during the combustion process, expanding in the common working space, simultaneously acts on the blades 3 of both rotors 2 and performs mechanical work directed to rotate the rotors 2. The remains of the exhaust gases of the previous cycle are removed from the working cavity 10 by blades 3 pushing them through constantly Open outlet at the same time as the working stroke.
The work of the rotary compressor is based on periodic changes in the volume of the working space. When the compressor blades 4 exit from the depressions 6 of the rotors 2, the volume of the inter-blade space increases, it creates a vacuum, and as a result of the pumping action, the working cavity of the compressor 11 is filled with external air. At the same time, air is compressed to the working space in the preceding cycle. The rotary compressor is valveless.
Regulation of the supply of compressed air from the compressor to the combustion chamber can be made by a valve or a spool.
As spools, motor rotors having apertures 13 in the end walls can be used, which are combined when they move with the apertures 14 in the end walls manufactured in the engine casing 1, to which the compressor discharge pipes 15 are supplied. In the cavities of the 16 rotors of the engine channels 17 are made, and in the side walls - windows 18 through which the compressed air enters the combustion chamber. Such a device will eliminate the use of a special valve mechanism. The effect of centrifugal forces on the air in the channels of the rotating rotor will increase the efficiency of its feeding. Part of the air supplied to the cavity 16 of the air rotors 2 can be used to blow the working cavity of the engine before feeding a fresh charge. And air can be supplied for cooling. Cooling of the engine can be liquid or air. Rotors 2 of the engine may have a cylindrical shape with parallel axes.
The compressor and the engine may have separate housings.
A device similar to a rotary compressor may have pumps. Performed as aggregates, rotary compressors and pumps can be driven from any type of engine.
The rotary engine may comprise several sections arranged in series.
On the rotors of the engine, several blades can be installed, each with a different number, and the same number of depressions, while the rotors must have diameters that are multiples of the number of blades on them, and the synchronizing gears equal the ratio of the rotor diameters to the gear ratio.
In order to avoid direct contact between the conjugate surfaces and the flow of gases between adjacent volumes, labyrinth seals 19 can be made in the end walls of the casing, the rotor and on the vanes, and on the sidewalls of the rotors there are sealing engaging protrusions and hollows 20 that provide compaction at minimum Sizes.
Synchronizing gears 7 can be used as a working member of a gear pump, for example in hydrodynamic transmission.
In order to balance the inertia forces, the compressor blades 4 and the motor 3 on each of the rotors and, accordingly, the cavities 6, 5 can be placed oppositely on the rotors.
Compression of air supplied to the combustion chamber can be effected by a compressor driven by a turbine rotated by exhaust gases or a separate supercharger.
Performing conical rotors of the engine makes it possible to reduce the dimensions, circumferential speeds, mass and wear of the synchronizing gears 7 and the mass of the engine as a whole.
The arrangement of the synchronizing gears 7 in a separate housing excludes their contact with combustion products, which makes it possible to use them as a working member of a gear pump.
The property of reversibility allows the use of the engine design for the manufacture of compressors and pumps.
The installation of the compressor 4 blades and the motor on the two rotors will allow to implement the work cycle processes in closed circuits, to reduce gas dynamic and volume losses.
The combination of the working cavities of the two rotors provides an increase in the working space and the degree of compression.
The distribution of the working process for individual working cavities provides practically simultaneous realization of compression, combustion and expansion processes, allows to increase the dimension and number of compressor stages, discharge pressure, and, consequently, to increase the parameters of the working fluid, to increase the torque and specific power.
The expansion process in the closed annular flow section, in which the velocity vector of the combustion products flow is normal to the working surfaces of the blades, provides a direct transformation of the energy of the working fluid into rotational motion of the rotors, an increase in efficiency.
Simultaneous and equivalent action of the working fluid on the blades of both rotors, mutually counterbalancing the effect of the rotors connected by means of synchronizing gears, the damping action of the compressor and the gear pump ensures uniform rotation of the rotors.
