Description

The invention relates to the field of mechanical engineering, in particular to compressor and engine-building.

The purpose of the invention is to increase the efficiency of a rotary machine.

FIG. 1 shows a longitudinal section of a rotary machine; FIG. 2 shows section A-A in FIG. one; in fig. 3 - implementation of the bypass channels in partitions (section B-B in Fig. 2); in fig. 4 shows a section of a CC in FIG. one; in fig. 5 - section rotor in communication with the high pressure cavity; in fig. 6 - socket.

The rotary machine comprises a housing 1 with inlet 2 and outlet 3 channels and two mating cylindrical bores 4, separated by at least one partition 5 into sections 6. B

each section 6 on parallel shafts 7 with the possibility of synchronous rotation and formation of suction, compression and injection cavities installed profiled rotors 8. The machine also contains end caps 9 and a gas distribution system, made in the form of inlet 10 and outlet 11 windows in end caps 9 and bypass channels 12 in intersection partitions 5. The rotors of 8 adjacent sections are deployed relative to each other. The radii of the boring 4 sections 6 are stepwise reduced. The rotors 8 of the adjacent sections 6 are rotatably mounted in opposite directions. The rotors 8 of the adjacent sections 6 can be mounted rotatably in one direction, wherein the input and output sections are XI Ov

The bypass channels 12 in at least one of the partitions 5 are located on opposite sides of one of the axes of symmetry of the bores 4. The synchronization unit of rotation of the rotors 8 contains shafts 13, 14, 15 on which the rotors 8 of the first, second and third sections 6 are fixed, respectively and timing gears 16.

On each shaft 15 there is a socket 17 fixed in the form of a cochlea with an increasing cross-sectional area. The outer side of the cover 9 in the high pressure cavity is installed with the possibility of simultaneous rotation in one direction under the influence of the screw 18 and periodically blocking the windows 1 of the worm gears 19, and on the outer side of the cover 9 in the low pressure cavity there are installed dampers 20. Each rotor 8 The third section is formed of a profiled channel 21, which forms a interface with the inner surface of the socket 17.

Rotary machine works as follows.

When the rotors 8 rotate through the inlet ports 10, the working medium is sucked in. As the suction cavity volume increases, the inlet ports 1O overlap the peripheral portions of the shutters 20, the working medium shrinks and is forced out of the discharge cavity of the first section 6 through the bypass channels 12 into the suction cavity of the adjacent second section 6. As the suction volume of the second section 6 increases, the channels 12 the peripheral sections of the end surfaces of the rotors 8 overlap. The working medium is compressed and forced out of the discharge cavity of the second section 6 through the channels 12

into the suction cavity of the adjacent third section b and then through the channels 21 in the rotors 8. exhaust ports 11 and sockets 17 to the exhaust port 3 of the machine.

The design of the rotor ma

tires increase efficiency.
