    摘要: A hydraulic system is disclosed having a source of pressurized fluid, at least a one hydraulic actuator, and a first valve. The first valve has a first valve element movable relative to a first valve bore between a plurality of positions from a first position in which pressurized fluid is substantially blocked from flowing toward the at least one hydraulic actuator to a second position in which pressurized fluid is allowed to flow toward the at least one hydraulic actuator. The first valve element is configured to be selectively moved from a third position located between the first and second positions to a fourth position located between the third and second positions at least partially based on a pressure signal of pressurized fluid downstream of the first valve.

    摘要: A swing control circuit is provided separately from a hydraulic actuator control circuit. The swing control circuit includes a swing pump motor connected to closed circuits of a swing motor through a solenoid valve that serves as a directional control valve. A swing motor generator is connected to the swing pump motor. The swing motor generator is connected to an electric power storage device of a hybrid type drive system. An exterior-connecting passage for feeding hydraulic fluid to hydraulic actuators of a lower structure and a work equipment is drawn from a pipeline between the swing pump motor and the solenoid valve. A connecting passage solenoid valve is disposed in the exterior-connecting passage. The invention enables hydraulic energy generated in the swing system to be directly fed to the outside of the swing system.

    摘要: A boom control circuit for controlling hydraulic fluid fed to a boom cylinder is provided separately and independently from a travel/stick/bucket control circuit, which serves to control hydraulic fluid fed to travel motors, a stick cylinder, and a bucket cylinder. The boom control circuit includes a boom pump, an energy recovery motor disposed in a return passage through which return fluid from the boom cylinder 8bmc passes, and a boom motor generator connected to the energy recovery motor. The aforementioned boom pump is connected through a clutch to the boom motor generator. The invention is capable of providing a work machine of which a boom control circuit is adapted to function independently so that the flow rate required by the boom control circuit can be easily ensured.
