8. Figures 1-7. The rack according to any one of claims 1 to 4 is connected together to the control input of an open-close travel valve 18. The pilot valve 18 is an exemplary remotely operated shut-off valve. Incidentally, the check valve 18 is incorporated in a conduit 22 which connects the space 20 below the piston 3 with the reservoir 21 through an opening 19 at the bottom of the expansion cylinder 2.

A throttle valve 23, 24 is connected to the atmosphere between one channel 10 and one check valve 11 and the atmosphere, and between the other channel 16 and the other check valve 17 and the atmosphere. , respectively. to provide air suction from the atmosphere.

Preferably, the filling vessel 27 is connected to the balancing vessel 21 via a line 22 between the balancing vessel 21 and the path valve 18 with a stopper 25 and a pressure gauge 26.

The energy storage rack works as follows:

The mass M on the load-bearing plate 1 is equalized by the pressure of air or gas enclosed in the balancing cylinder 2. When lifting the weight M, When lowered, the balancing air or gas flows into or out of the balancing vessel 21. from there back. The flow is through the two-way road 182 Valve. This is the main circuit for balancing the stand.

The principle of balancing the rack is that, when at rest, the travel valve 18 disconnects the balancing cylinder 2 from the balancing tank 21, thereby automatically applying a balancing pressure M in the balancing cylinder 2. However, if the rack is moved in any direction with the mass M, the valve 18 will allow free flow between the balancing cylinder 2 and the balancing tank 21 so that the volume change 20 of the piston 3 of the balancing cylinder 2 may be compensated. As the volume 28 above the piston 3 of the balancing cylinder 2 also changes, the space 28 must be connected to the atmosphere via an arrow 29.

The channels and fittings connecting the control cylinder 6 to the control valve inlet 18 form a secondary circuit for the rack balancing apparatus. In the example, the control cylinder 6 is configured such that the control cylinder 6 moves and the control piston 5 stands relative to the balancing cylinder 2. After the inner channel 8 of the piston rod 7, formed as a double-walled tube, the space 9 above the control piston 5 is connected via one channel 10 and one throttle check valve 23, while the tube 12 connects the space 15 below the control piston 5 through the other throttle valve 55 to the atmosphere, one through the non-return valve 11, or in turn, it is connected via a non-return valve 17 to the control input 18 of the check valve. If the piston 3 is in any direction e.g. As it moves upward, air from the space 15 is discharged through the upper opening 13, the pipe 12, the lower opening 14, the other channel 16, and the other throttle check valve 24. the other opens the way valve 18 through the non-return valve 17 and the control valve inlet of the way valve 18, so that the increased space 20 has an embodiment 65, characterized in that the way valve (18) is a remotely controlled shut-off valve.
