The technical result is simplified and reduced the price recovery performance rackmount hydropneumatic shock absorbers, increases their lifespan, simplifies the design of shock absorbers and expands the scope of use. 5 Il.

The invention relates to road transport and relates to devices for recovery of operating characteristics of hundred what costly shock absorbers ZAZ-1102, M-2141.

A device for filling the working fluid of a hydraulic shock absorbers, including tools for disassembly and Assembly of the shock absorber and the fluid in the working cavity of the shock absorber through his shutoff valve [1].

The disadvantage of this device is that it is applicable when there are special stands for service stations and is intended to restore the operating characteristics of the shock absorbers having a shutoff valve for shock absorbers cars "Moskvich", "Tavria", and rack-mounted hydro-pneumatic dampers foreign firms "KYB", "TOKIKO", "MONROE," it is unacceptable due to the lack of shut-off valves.

Closest to the proposed device is a device for the recovery performance hydro-pneumatic rack damper, comprising a cylinder of compressed gas shut-off equipment, high pressure hoses and fittings for the supply of gas in the absorber. [2].

The disadvantage of this device is

the complexity of the design of shock absorbers because of the need for supply shut-off valves, which increases production costs and total work at zapravka echnik dampers foreign firms "KYB", "TOKIKO", "MONROE" due to the lack of shut-off valves;

the need for special stands for refills absorbers.

The invention consists in that the device for restoring the operating characteristics of hydropneumatic rack damper, comprising a cylinder of compressed gas shut-off equipment, high pressure hoses and fittings for the supply of gas in the absorber with gazonapolnitel that includes the specified socket for the supply of gas in the absorber and consisting of a body with a truncated penetrating the lower part with an inner diameter corresponding to the diameter of the rod is filled shock absorber, upper cover with pressed therein by the seal and o-ring.

In the proposed device the new features are

the presence of the device gazonapolnitel;

implementation of the internal diameter of the truncated penetrating the bottom of gazonapolnitel corresponding to the diameter of the rod is filled shock absorber;

no need to supply damper shut-off valve.

When reaching these features are provided by a new positive properties:

simplifying and cheapening vosstanovlenie the hydro-pneumatic dampers foreign firms "KYB", "TOKIKO", "MONROE";

to simplify the design of shock absorbers;

expanding the field of use of the device;

the possibility of using the device to restore operational characteristics of the hydraulic shock absorbers ZAZ-1102, M-2141.

Thus, the proposed device meet the criterion of "novelty."

The device illustrated by the drawings, showing:

The device R is Isadora (the device which is similar to device hydraulic rack absorbers ZAZ-1102, M-2141 [1]) is put on gazonapolnitel (Fig. 1) that run down the stem (6) to contact with a sealing gasket (7) shock and slightly nadavlivaya, with truncated penetrating part of gazonapolnitel enters the cavity sealing gasket (7) of the shock absorber. The fitting gazonapolnitel is connected to the source of gas and is filed the necessary pressure. The prevailing pressure in the cavity of the gland enlarges the working edge (8) of the seal, and the gas flows into the tank (12) 2-tube shock absorber through the existing drain holes (9) distance sleeve (10) of the shock absorber. After filling with gas shock absorber truncated penetrating part of gazonapolnitel removed from the cavity sealing gasket (7) shock absorber, gazonapolnitel removed from the rod (6) and the shock absorber is ready for use.

For the fabrication of the proposed device gazonapolnitel is made of steel of any grade with an inner diameter of the truncated penetrating part of the body of gazonapolnitel corresponding to the diameter of the shock absorber rod, a sealing gasket used serial.
