Description

one

The present invention relates to the field of inkjet technology, namely to pneumatic generators.

A pneumatic generator with a mechanical resonator in the form of an elastic plate is known, overlapping, with its feedback channel. The disadvantage of such a device is its low-tech, as well as the inability to change the frequency and amplitude of periodic oscillations.

Another pneumatic generator is known, comprising a flexible receiving element with inlet and outlet channels and a power nozzle, the axis of which is offset relative to the axis of the inlet channel.

The disadvantage of such a device is the low-tech design, as well as the impossibility of changing the frequency and amplitude of the periodic oscillations.

The purpose of the present invention is to simplify and expand the functionality of the device. This goal is achieved by the fact that the receiving element is designed in the form of a tube fixed on the side of the output channel in a support mounted for movement along the axis of the tube.

The drawing shows a pneumatic generator, which consists of a flexible receiving element 1 in the form of a tube with inlet and outlet channels and a seat 2, whose axis is displaced relative to the axis of the inlet channel of the flexible tube so that the hole of the power nozzle partially overlaps the inlet of the elastic tube, which is output channel is fixed in oiore b. To the output channel is connected deaf camera measuring device 4.

The generator works as follows. Feed nozzle 2 to CN: AIR

under pressure PO. Due to the displacement of the axis of the flexible element 1 relative to the axis of the nozzle of the power supply 2, a part of the jet flowing out of the latter with a certain speed gets into the element 1, and a part washes it. In the zone

When the tube is washed, the pressure drops below atmospheric pressure, and the pressure in the tube itself rises, which is recorded by the measuring device 4. Under the effect of the resultant force, the tube starts to bend towards the ionic pressure. The pressure in the tube and the pressure continues to rise, and when the opening of the socket and the titanium 2 completely closes the opening of the element 1, the pressure in the tube reaches its maximum.

As a result of the bending of the tube, a surface is formed at an acute angle to the flow, which is exerted by the pressure of the jet, which causes further bending of the element 1. Its bending continues until momeite, when the opening of the nozzle pggani partially overlaps the inlet of element I on the other side. At the same time, the pressure in the tube decreases, which is registered by the device 4. At the same time, in the flushing zone of the tube, the zhe on the other side decreases to less than atmospheric. This is a drive to change the bending direction of the tube. The bending of the tube in the opposite direction also contributes to the elasticity of the tube itself. The amount of bending may be limited depending on the elasticity of the tube. When moving back in element 1, the pressure rises to the maximum, and when approaching the extreme position, it starts to decrease. The cycle is repeated. Thus, periodic tube oscillations occur. Generator to be used as a generator of mechanical vibrations. To do this, it is necessary that the surgeon's tube from the outlet side is plugged (like a deaf camera). By moving the attachment point of element 1 in support 3 along the length of the tube, it is possible to change the frequency and amplitude of oscillations at constant pressure. Pneumatic generator containing flexible input element with input and output channels and a power nozzle whose axis is mixed with respect to the axis of the input channel, differing in that, in order to simplify and extend the functionality, the receiving element is designed as a tube fixed on the output channel side in a support mounted for movement along the tube axis.
