Abstract
A mechanical power regeneration system for a movable object comprising a sole variable displacement hydraulic pump being driven by the movable object, a first check valve connected between the output side of the pump and a first hydraulic line of a high pressure accumulator unit, a second hydraulic line of a low pressure accumulator unit, a second check valve connected between the second hydraulic line and the input side of the pump, a first controlled valve connected between the first hydraulic line and the input side of the pump and a second controlled valve connected between the second hydraulic line and the output side of the pump. When the movable object is to be slowed down by placing it in a braking mode, hydraulic fluid is transferred by the pump from the low pressure accumulator to the high pressure accumulator. When the movable object is placed in a drive mode, stored energy in the high pressure accumulator is transferred to the input side of the pump to apply a positive traction force to the movable object.
