Abstract

The hammer comprises bases (1, 2) between which is located a force casing (3) capable of axial movement. The casing (3) interacts with the bases (1, 2) through tie elements (4) with dampers (5). The bases (1, 2) are connected with the striker (7) by means of flexible diaphragms (8, 9). The striker (7) is provided with a central opening in which is mounted a valve (12).

The invention may be used for various technical and vibrational shock loads of 10 load-bearing elements in the load.

The prior art Β presently, various types of pneumatic-impact machines are known. Β chasτnοsτi izveeτna, naπρimeρ machine, sοdeρzhaschaya κορπus, vnuτρi κοτοροgο 15 ρazmeschen udaρniκ and vοzduχορasπρedeliτelnοe usτροysτvο, πρichom κορπus vyποlnen of τρeχslοynοgο maτeρiala: slοy uπρugοy πlasτmassy zaκlyuchen between τοnκimi sτalnymi lis- τami, πρi eτοm meχanichesκy noise vοzniκayuschy πρi ρabοτe machine in gasiτsya sounding abscissa. 20 The cost of the device is a complicated construction due to the fact that the body of the machine is multi-functional.

Also known is the vibration exciter (υυ, Α, 1362783), which is justifiable, between the elastic through 25 diaphragms the device has been protected, and the device has been disconnected.

The cost of the device is low reliability. This is due to the fact that shock loads are carried out by all parts of the hard drive, which leads to a decrease in their 30 service life.

Another disadvantage is the increased level of aerodynamic and mechanical noise. This is due to the fact that the resultant exhausted air is emitted directly to the atmosphere, and that emits emanating noise, which emits no noise.

The purpose of the present invention is the elimination of the aforementioned deficiencies described above pneumatic - 2 - tires hit the road.

Otherwise, the execution of the best results in the basic knowledge of loading the load in the pipe makes it possible to use a larger amount of noise.

The use of the invention makes it possible to create a considerable reserve of parts in parts, which increases the long-term profitability). - 3 - garbage and mechanical noise of pneumatic lift. However, studies have established that sound pressure levels are reduced by approximately 12 decibels. 5 Quick Descriptions of Drawings

The following is a discreet version of the present invention and the drawing, at the same time, a small number of pearls are shipped according to the invention.

On December 20, on July 13th, it was shipped to the other side of channel 14; Relatively to the 12 prisoner on the grounds of 1.2, the springs Ι £, 20 were reserved. There are excellent answers on 21, 22.

25 Κ bottom base 2 the clogged element is broken, for example, clause 23.

The device operates the following way. The compressed air will open the channel (not indicated) in the base I on the working camera 10 and after that, the output will be removed from this channel.

30 channels 16 - on camera II. section 8, 9 is pressurized, the air is bent, and, as a result, bend outside section 9 is less than the bend, because

35 7 of the working camera ΙΙ, larger than the working camera 10. Alarm 7 starts to lift up. The prisoner 12 is squeezed by the pressure of the squeezed air inlet 14. By this location, the prisoner 12 is located - 4 - there are 15 output channels, and 16 output channels are output. Sounder 7, having reached its previous location, is crashed by devices 13 into the bowl 19 and compresses it.

15 airways. The final response 21 is at the same time as the upper part of the shocker 7, and the final response is 22. Developed air, expanding, it will exit through exhaustive openings 22 in the atmosphere. Β The output is pulsed and the pressure pulsed at the exit to the atmosphere.

20 years are smoothed out, which leads to a decrease in the sound power of the source of aerodynamic noise.

Β in case that the loading unit is a pipe, the processed air will be released through exhaust pipes 22 inside the pipe, where there is a pipe

25 It is fully expanded.

Then, drummer 7 by the pressure of the compressed air in working chamber 10 starts moving to the working chamber II, and thus the process is in progress. 21.

Β in the event that the loading element is a pipe that has been removed from the internal area of the pipe, after which there are 22, and then after

35 Aperture 21 is released in the atmosphere, which results in even higher noise dampening performance.

Movement of the striker 7 is forwarded to him, but he will not strike at the base of 2 and scattered with it - 5 - hard-to-clog items.

10 blows have a casing for a moment that disconnects, compressing the dampers and even more so, that is, the casing is not hard. Therefore, in the pneumatic youth, the strength of the outer shell, or the grounding and pulling elements, are unloaded for significant shock loads, which increase

15 are honored.

When shock occurs in base 2, it emits high frequency vibrations, which is a source of noise, but the shock is not possible.

20 for a power supply of 3 or more, the foundation of I, and as a result of that, of the base 2, a significant axial force of the dampers, there is an increase in the frequency of vibration Thanks to the reduction of vibration,

25 Particular excitation of the body at a shock and shock, and also the vibration reduction of vibration reduces mechanical noise.

The intentional applicability of this invention may be subject to change.

30 Tan and various components and modifications of pneumatic youth are manufactured. Such devices may be used for loading into the load of the pipes and the well-being for the sinking of the mediums of property

35 nights Otherwise, on the basis of this invention, highly effective young people can be produced to be able to work in dual conditions. - 6 -

The frequent components of the design are low-energy-consuming, simple and reliable, small in size, and environmentally friendly.
