摘要： The purpose of the present invention is to provide a hydraulic shovel: with which pressure interference during combined operation of a boom cylinder, an arm cylinder and a bucket cylinder can be avoided; which improves usability; and which can reduce horsepower loss. The hydraulic apparatus is set so that the ratio of the pressure-receiving area (B) of the respective bottom oil chambers (35) of the boom cylinder (16), the arm cylinder (17) and the bucket cylinder (18) to the pressure-receiving area (R) of the respective rod oil chambers (36) matches the ratio of the extruded volume drawn into or discharged from the bottom oil chambers (35) per single rotation by the respective extrusion members of the first hydraulic pump motor (30), the second hydraulic pump motor (31) and the third hydraulic pump motor (32) to the volume discharged from or drawn into the rod oil chambers (36).

摘要： To provide a speed controller capable of controlling an action speed of an external cylinder in one stroke in a step-wise manner.
The speed controller (1) includes a first flow path (16) and a second flow path (18) that allow a first port (12) and a second port (14) to be in communication with each other. The first flow path (16) is provided with a first check valve (28) for allowing flow from the first port (12) to the second port (14). The second flow path (18) is provided with a first needle valve (32), and an opening hole (28d) of the first check valve (28) is constituted as a part of a flow path. The first needle valve (32) adjusts the flow rate by changing an opening area of the opening hole (28d) with a tip portion (34a) fixed on a piston (30) in the cylinder chamber (20). The speed controller (1) further includes a third flow path (22) allowing the first port (12) and the cylinder chamber (20) to be in communication with each other. The third flow path (22) is provided with a second check valve (46) for allowing flow from the first port (12) to the cylinder chamber (20).

摘要： Provided is a work machine using a hydraulic motor and an electric motor to drive a swing structure, the work machine being adapted to reduce fuel consumption in regions where swinging by the hydraulic motor is prone to deteriorate in efficiency, such as when an operating stroke of swinging is small. The work machine includes an engine, a hydraulic pump driven by the engine, a swing structure, an electric motor for driving the swing structure, a hydraulic motor for driving the swing structure, the hydraulic motor being driven by the hydraulic pump, and a swing control lever device that commands the swing structure to be driven. The work machine further includes a control device operates in either an electric swing mode in which the swing structure is driven mainly by torque of the electric motor or a hydraulic swing mode in which the swing structure is driven mainly by torque of the hydraulic motor, depending on an operating stroke of the control lever device and/or a swing speed of the swing structure.

摘要： A control valve apparatus includes a second-working-actuator acceleration control valve connected to a first working control valve in parallel. The second-working-actuator acceleration control valve includes pilot chambers receiving a pilot pressure for switching first and second working control valves and a flow channel that guides a pressure fluid of a first pump port to an entrance port side of the second working control valve. The second-working-actuator acceleration control valve is switchable between a first priority position in which a pressure fluid is guided to the first working control valve with a higher priority than the second working control valve and a second priority position in which a pressure fluid is guided to the second working control valve with a higher priority than the first working control valve.
