Hydraulic energy recovering/regenerating apparatus
First Claim
1. A pressure oil energy recovering/regenerating apparatus comprising:
- recovering means for recovering return pressure oil from at least one hydraulic actuator and converting the return pressure oil into energy;
regenerating means for taking out the energy output by said recovering means; and
driving means which is adapted to be driven by the regenerated energy taken out by said regenerating means.

Abstract
Return pressure oil from a pressure oil actuator is supplied to a hydraulic pump/motor as recovering means through a supplying circuit. The hydraulic pump/motor serves as a motor, and a hydraulic pump/motor as regenerating means which is mechanically connected to the first-mentioned hydraulic pump/motor is allowed to serve as a pump. The pressure oil discharged from the second-mentioned hydraulic pump/motor is supplied to a hydraulic pump/motor as driving means and can be stored in the accumulator. The hydraulic pump/motor as the driving means is driven by the pressure oil discharged by the second-mentioned hydraulic pump/motor and the pressure oil stored in the accumulator. With this arrangement, it is possible to recover the energy of the return pressure oil from the pressure oil actuator and to regenerate the recovered energy to be driving energy in the driving means.
