Phie.1

The invention relates to inkjet technology and can be used for pumping liquids or gases.

The purpose of the invention is to increase efficiency by expanding the range of adjustment of the performance of the apparatus.

FIG. 1 shows a jet apparatus, a longitudinal section; HI of FIG. 2 shows a section A-A in FIG. FIG. 3 is a section BB of FIG. one.

The jet apparatus contains a mixing chamber 1, a diffuser 2, a nozzle 3 for supplying an active medium, a peripheral and a cylindrical central nozzle 4 and 5 for supplying a passive medium, an annular active nozzle 6, made of inner and outer envelopes 7 and 8. The output section of the active the nozzle 6 is located in the inlet section of the mixing chamber 1. In the inner shell 7 there are rows of channels 9 connected to the nozzle 3 for supplying the active medium and oriented in the direction towards the mixing chamber 1, while the projections of the axes of the channels 9 to the longitudinal and cross sections of the apparatus are angled respectively to the axis of the apparatus and the radius of the cylindrical central nozzle 5. Between the shells 7 and 8 is installed a sleeve 10 fixed on the outer shell 8 and in contact with the inner shell 7, and the latter is mounted for axial movement relative to the outer shell ki 8 and overlap the channel 9. The central tube 5 to the nozzle 3 compound active fluid through the bellows 11.

Inkjet apparatus operates as follows.

The active medium through nozzle 3 is supplied to the apparatus and enters the annular nozzle 6 and channels 9. After flowing out of channels 9 in the direction to measure 1 mixing at an angle to the axis of the apparatus and to the radius of the central cylindrical nozzle 5, the active medium ejects a passive flow the medium entering through the central nozzle 5 is mixed with it and supplied through

inner shell 7 into the chamber 1 mix. Another part of the active medium flows directly into the annular active nozzle 6 and then into the mixing chamber 1, thereby ejecting a flow of the passive medium entering the apparatus through the peripheral port 4. Mixing both media occurs in chamber 1, and increasing the pressure in the diffuser 2 when braking the flow. When the pressure of the active medium changes, the inner shell 7 has the ability to move relative to the outer shell 8 when the bellows 11 is deformed, thereby changing the geometry of the annular nozzle 6, as well as the number of rows of channels 9 in the inner shell 7 open to the passage of the active medium, which It allows automatic changing of the mixing conditions and the ejection coefficient, which increases the efficiency of the apparatus.
