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 7):
The hydraulic driving apparatus for work machine according to  claim 5 , wherein:\n the pressure holding valve is an accumulator opening/closing changeover valve that is provided at a position between the first pump motor line and the first accumulator, and can be switched between an open state of causing the first pump motor line and the first accumulator to communicate with each other and a blocked state of blocking the first pump motor line and the first accumulator from each other; and the circuit switching unit brings the accumulator opening/closing changeover valve into the open state in the first regeneration mode, and bringing the accumulator opening/closing changeover valve into the closed state in the second regeneration mode.
