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 9):
The hydraulic driving apparatus for work machine according to  claim 8 , wherein the circuit switching control unit switches the circuit switching unit to the drive mode while such a condition that an operation of driving the first driving subject at a constant speed or an operation of accelerating the first driving subject is given to the operation apparatus is required as a necessary condition, switches the circuit switching unit to the first regeneration mode while such a condition that an operation of decelerating the first driving subject is given to the operation apparatus is required as a necessary condition, and switches the circuit switching unit to the second regeneration mode while such a condition that the operation relating to the driving of the first driving subject is not given to the operation apparatus is required as a necessary condition.
