Abstract:

In the paper is analyze the hydraulic possibilities for energy recovery-storage of the vehicles variable (rectilinear, horizontal and curvilinear) movement on the base of some hydraulic scheme, using hydraulic pistons with large inner surfaces S, which is generating important pressure forces, used for actuating of some rotary volume pumps, multiplier of pressure, charged from a central tank with liquid, placed on the height h, with the flow rate Q in time t of the relative movement. In the accumulator is stocked hydraulic energy with multiplied pressure pacc and flow rate Qacc (fraction of the flow rate Q). There are making evident the determinant influence factors and the practical possibilities of energy recovery degree increasing. In the study is showed a numerical application.

Keywords:
