ABSTRACT:
A compact hydrostatic energy recuperation system comprises hydrostatic converter with first and second pump-motors, which shafts fastened by coupling. The first pump-motor having greater displacement volume associated with the machinery working equipment hydraulic system by hydraulic distributor. The second pump-motor associated with the pneumohydraulic accumulator by two-position valve.The hydrostatic converter increases the working equipment pump suction oil pressure and the pump specific power.The hydrostatic converter charges the pneumohydraulic accumulator with boosted oil pressure and smaller oil volume magnitude during the working equipment lowering and considerable decrease the energy recuperation system installation space, weight and cost.The hydrostatic converter provides the pneumohydraulic accumulator discharge and transmitted this additional energy to the working equipment pump during the most energy consuming load lifting process. This realizes the automatically working energy recuperation system great potentiality of the fuel consumption and toxic exhaust decrease.
