The invention relates to an inkjet machine and can be used in (pulleys for compressing vaporous media.

The purpose of the invention is to increase efficiency.

FIG. 1 is a schematic depiction of the described ejector; Fig, 2 - nozzle section of the ejector with cylindrical nozzles; FIG. 3 shows the section of the section of the ejector at the installation site of the pylons.

The ejector contains a mixing chamber 1, concentrically mounted in the receiving chamber 2 annular active nozzles 3, forming annular channels 4 for supplying the passive medium and having sections in the same plane, and radial nozzles 5, Kayals 4 for supplying the passive medium provided with nozzle nozzles located at their outlet 6, and the active nozzles 3 through the radial nozzles 5 communicate with each other. The ejector is provided with cylindrical nozzles 1 with outlet nozzles 8 concentrically installed in the channels, and the peripheral nozzle nozzle 9 is offset relative to the section of the active nozzles 3 towards the mixing chamber 1. The ejector is equipped with two rows of radial pylons 10 fixed to the walls 11 of the active nozzles 3 and the pipes 7, the walls 11 and the pipes 7 being provided with recesses 12 on one side, and the pylons 10 are located in the latter,

During the operation of the ejector, the active gaseous medium, having exhausted from the annular active nozzles 3, carries the passive gaseous medium into the mixing chamber 1 through the channels 4 to supply the passive medium through the nozzle nozzles 6 or through the nozzle l

nozzles 6 and output nozzles 8. In the mixing chamber 1, the active and passive media are mixed and then transferred to the flow part with a corresponding mjiM change in the ratio between the kinetic and potential energies of the mixture of media,

Thus, such an implementation of the ejector allows to reduce the amount of energy loss when mixing active and passive media, which increases its efficiency.
