Abstract

The invention can be used for pressurization of internal combustion engines. The purpose of the invention is to increase efficiency by expanding the range of operating conditions. For this, the additional channels communicated with the cells 1 and adjacent to both side walls of the window 7 for the discharge of compressible gas (SG) are divided by partitions 9 into chambers 10 and 11 communicated with the main channel 8 for the removal of SG. Moreover, the camera 10 and 11 are at the outlet check valves 12 and made in the form of diffuser channels. As a result, when the operation mode changes, the number of chambers 10 and 11 changes through which the SG is withdrawn, which allows the edges of the window 7 to be shifted, as it were, without reducing its flow area. 1 hp ff, 1 ill.

The invention relates to power engineering, in particular to pressure wave exchangers designed to pressurize internal combustion engines.

The purpose of the invention increase efficiency

by expanding the range of operational modes.

The figure shows wave exchange pressure.

Wave pressure exchanger contains

In addition, chambers 10 more distant from the leading edge of the window 7 also operate. Thus, the number of chambers through which the compressed air is discharged increases, which is equivalent to an earlier connection of the gas exchange cell 11 to the channel 8.

By reducing the rotor speed, the number of chambers 11 through which the ocyuiecTB removes compressed air decreases.

the body (conventionally not shown), placed Yu since the rarefaction wave, is formed in it by a rotor with gas-exchange cells 1ma when cell 1 is disconnected from window 4,

and two end plates 2 and 3. In plate 2

Windows 4 and 5 are made for supplying and discharging compressive gas, and in plate 3 windows 6 and 7 are made for supplying and discharging a minimum gas g, communicated respectively to the channel for supplying compressible gas (conventionally not shown) and to channel 8 to compressible gas. Additional channels are also made in the plate 3, which connects the plates 3 at the moment of the connection of the cell in question to the near (during the rotation of the rotor) chamber II.

With an increase in the frequency of rotation of the rotor or a decrease in the pressure of the compressed gas, the opposite is done to the described measurement of the number of chambers 10 and 11 that are included in the operation.

Screwed with cells 1, adjacent to the rim of the springs of check valves 12 provide the side walls of window 7 and are divided by partitions 9 into chambers 10. II. Chambers 10 and 1 1 communicated with channel 8 and made in the form of diffuser channels. At the outlet of the chambers 10 and 11 are installed check valves 12, which prevents the flow of compressed gas from the channel 8.

The gas-dynamic exchange cycle is as follows.

When combining the gas exchange cell 1 of the rotor with window 4, a pressure wave propagates along it, compressing the gas - air. By the time the wave reaches the right end of the rotor, cell 1 is in communication with one of the chambers 10 and the compressed air enters this and subsequent (during the rotation of the rotor) chamber. 35 As the air moves in these chambers 10, the kinematic energy of the flow is partially converted into potential, due to which static pressure in chambers 10 rises, which ensures discharge of compressed air through valves 12 to channel 8. This process continues when cell 1 communicates with the window 7, as well as with chambers 11 until reaching the right end of the rarefaction wave rotor. In the process follow

The preservation of the residual pressure in gas exchange cell I, the minimum necessary for purging it, is maintained. The implementation of chambers 10 and II in the form of diffuser channels contributes to the conversion of part of the kinetic energy of compressible gas - air into potential, due to which the static pressure in operating chambers 10 and II in the zone of check valves 12 slightly exceeds the static pressure in the main channel 8 for removal of compressible gas which allows the discharge of air from chambers 10 and 1 I into channel 8.
