Abstract:
A hydraulic driving apparatus that drives a plurality of driving subjects and regenerates energy thereof. This hydraulic driving apparatus includes: a first pump motor; a second pump motor that is switchable between a state of moving a first driving subject by hydraulic oil discharged from the first pump motor and a state of being operated as a pump by means of energy of the first driving subject; a first pump motor line that couples the first and second pump motors with each other; a first accumulator connected to the first pump motor line; a regeneration subject hydraulic actuator that moves a second driving subject; a second accumulator that receives hydraulic oil from the regeneration subject hydraulic actuator; a second pump motor line that couples the second accumulator with the first pump motor; and a pressure release changeover valve that opens/closes the second pump motor line.

Claim (Index 5):
The hydraulic driving apparatus for work machine according to  claim 1 , further comprising a circuit switching unit that has a plurality of modes, wherein the plurality of modes include:\n a drive mode of bringing the pressure release changeover valve into the closed state, bringing the first pump motor into the first pump operation state, and bringing the second pump motor into the second motor operation state, thereby enabling the second pump motor to be driven by the hydraulic oil discharged by the first pump motor; a first regeneration mode of bringing the pressure release changeover valve into the closed state, and bringing the second pump motor into the second pump operation state, thereby enabling the hydraulic oil discharged by the second pump motor to be introduced into the first accumulator; and a second regeneration mode of bringing the pressure release changeover valve into the open state, and bringing the first pump motor into the first motor operation state, thereby enabling the first pump motor to operate as a motor by means of the pressure release from the second accumulator to the first pump motor.
