;

The invention relates to devices for exciting oscillations and can be used in construction and other sectors of the national economy.

The purpose of the invention is to stabilize amplitudes of oscillations, reduce exhaust noise and increase the energy of a single blow.

Fig 1 shows a cross section of a vibratory exciter with a drummer placed on an immobile support; Fig 2 shows a vibrating exciter at the moment of exhaust with a percussion mounted on a vibrating organ

The vibration exciter consists of a vibrating organ 1, a drummer 2 with a shock pad 3, an elastic diaphragm 4 with exhaust windows 5, a force and exhaust half 6 and 7, a power supply and exhaust valve 8 and 9, a sleeve 10 with fifth 11, The coyura has a peripheral groove 12, which forms with the thiafragm an additional exhaust gas pipe 13, the grooves 14 connecting cavities 7 and 13, an additional donation platform 15, a bypass channel 16 and return elements 17

Vibrovozbu ipel works as follows

in a way

In the initial state of the window 5 of the block of the fifth 11 When the compressed air is supplied through the canal 1N, the pressure in the power strip 1i () increases and the pattern moves from upwards. The inserted organ 1 moves upwards of the microwave pressure pressed to it 5 seconds. 10 (in the embodiment according to Fig. 1) or down (Fig. 2) along the sleeve () with respect to the vibrating organ 1, and the return elements 17 are compressed. This movement has occurred xoiiii W until 5 rgzko shoves hack as waste

through the windows 5, the cavity 13, the pins 14 enters the exhaust cavity 7 and is led outside.

As a result of the expansion of air into the cavity 7 and 13, the flow velocity drops,

consequently, the exhaust noise is reduced. Under the action of the energy of the returning elements 17, the impactor 2 returns to its original state and strikes through the impact pad 15 on the p 11 with a vibrating

The organ 1 of the window 5 overlaps the heel 11, the cavity 6 is sealed and the cycle repeats
