    摘要: A hybrid construction machine includes first and second main pumps, first and second supply passages, first and second circuit systems, a hydraulic motor, a motor generator, an assist pump, a joint passage connected to the assist pump and branched off, first and second logic valves, a switching valve disposed in the other branch passage and switchable to a state where the assist pump is connected to the second supply passage on the upstream side of the second logic valve and a state where the second main pump is connected to the hydraulic motor, and a check valve. A poppet diameter of the first logic valve is smaller than that of the second logic valve.

    摘要: A relief valve includes an adjusting piston which is slidable by the action of a pilot pressure, a pilot poppet on which a spring force of a setting spring adjusted by a sliding movement of the adjusting piston acts in a valve closing direction, a spring chamber into which a spring for exerting a spring force opposing the pilot pressure is incorporated, and an air vent hole which is formed in the spring chamber and exposes the spring chamber to outside.

    摘要: A hybrid construction machine includes first and second main pumps, first and second supply passages, first and second circuit systems, a hydraulic motor, a motor generator, an assist pump, a joint passage connected to the assist pump and branching off, first and second logic valves, and a switching valve. The switching valve switches between a state where the assist pump is connected to the second supply passage and a state where the second main pump is connected to the hydraulic motor. The hybrid construction machine includes a bypass passage branching off from the other branch passage at the downstream of the switching valve. The bypass passage is connected to the second supply passage on the downstream side of the second logic valve.
