Ierbretenio refers to the means of oscillation in mechanical engineering.

A vibration damper is known, containing a body filled with a working medium, a mass placed in it with a hole along the damper axis and the elastic elements l connecting the mass with the body.

The disadvantage of this damper is its low efficiency due to the large mass.

The shock absorber is closest to the image, the case is filled with a working medium, a maos with two cavities and a hole connecting them along the axis of the damper, marked -15 in the case with a gap in outer diameter and made of a material whose density is less what is the working environment and the elements that connect the mass with the housing G 2 3-20

The disadvantage of the known quenching & low degree of damping due to the low rate of dissipation of the energy of dynamic loads.

. The purpose of the invention is to increase the efficiency of damping.

This goal is achieved by the fact that in the vibration damper, comprising a housing filled with a working medium, a mass with two; m cavities and a TwetA orifice connecting them along the axis of the quencher, placed in the housing with a gap in the outer diameter and made of a material whose density is less than the density of the working medium, and elastic elements connecting the mass with the housing, in a mass ejected Yen conical channels, connecting the cavity with a gap in facing the gap with a large base. At the same cone

channels are tangentially polooooo.

FIG. 1 shows a vibration damper, longitudinal section; HEI FIG. 2 mass with a tangential arrangement of conical channels relative to the cavities.

The vibration damper has a housing 1 filled with a working medium, a mass 2 with two cavities 3 and 4 and a hole 5 connecting them, and an elastic element 6.

The oscillator is mounted on object 7. Mass 2 is placed in housing 1 with a gap of 6, made of a material whose density is less than the density of the working medium, and has conical channels

9 and 10, connected to the gap 8 by a large base and connecting cavities 3 and 4 of mass 2 with gap 4 8. In this case, the channels 9 and 1 O can be located

 tangentially cavity 3 and 4.

The device works as follows.

When the object 7 oscillates, the mass 2 acts alternately in the direction of the repulsive force. As a result, the mass 2 makes translational movements relative to the housing 1. The working medium is periodically squeezed through the hole 5, the tapered cable 9 and 1 O, and the gap 8. As the working medium flows through the tapered channels 9 and

The 10th speed decreases while simultaneously increasing the pressure in the gap 8, which ultimately leads to an increase in the speed of the oscillation energies of the object 7. When the conical channels 9 and 10 are made, the tangential cavity 3 and 4 of mass 2 n progressively moves in the housing 1 rotational oscillations, which causes a very heavy movement of the working medium in the gap 8, which additionally consumes the vibrational energy of the object 7. Therefore, the efficiency of the vibration damper in the case increases.

The application of the proposed damping oscillation rh will increase its damping ability while reducing dynamic loads.
