Abstract: When boom lowering operation for operating a boom cylinder (6) by an external load (W) and an arm cylinder (26) or a bucket cylinder (27) are interlocked in the air, a first changeover valve for boom (2) is controlled to neutral position and a boom regeneration valve (13) is controlled to open position. Since working oil is regenerated from a line (9) on the working oil return side of the boom cylinder (6) through the boom regeneration valve (13) to a line (5) on the working oil supply side, the working oil supply from a hydraulic source (4) to the boom cylinder (6) is not required and a larger quantity of working oil can be supplied from the hydraulic source (4) through a second changeover valve for arm (24) or a changeover valve for bucket (25) to the arm cylinder (26) or the bucket cylinder (27). Working speed of the arm cylinder (26) or the bucket cylinder (27) can thereby be increased and work efficiency of a hydraulic shovel can be enhanced at the time of interconnecting operation.

Abstract: The present invention may be used in excavators, cranes, manipulators, loaders and bulldozers as well as in other machines with multiple engines or in cyclic-action mechanisms comprising hydraulic cylinders and motors. This invention essentially relates to a hydraulic actuator which exhibits high energy-saving capacities due to its reduced fuel and power consumption during combined operations. This device also has an improved reliability and causes little thermal losses thanks to the volume adjustment and energy recovery. The hydraulic actuator of the present invention comprises a pump unit, hydraulic cylinders, hydraulic motors, an inflow and cooling unit, hydraulic distributing devices as well as a working-fluid tank. The pump unit includes at least two adjustable double pumps each consisting of two hydraulic reversible machines having different and varying working volumes. The two hydraulic reversible machines are fitted with control units and are kinetically connected together. The chambers of the hydraulic reversible machines having the largest working volume are connected in closed loop to the chambers of the hydraulic cylinders and motors. One of the chambers of said machines having the smallest working volume is connected by a hydraulic distributing device to the piston cavity of a hydraulic cylinder or to the tank, while the other chamber having the smallest working volume is connected to said tank. The relation between the diameters of the pistons and the diameters of the hydraulic cylinder rods is a function of the relation between the largest and the smallest working volumes of said hydraulic reversible machines.

Abstract: This fluid control mechanism has a divergent flow selecting valve means (52) adapted to change pressure fluid admission passages extending from two main pumps (40), (50) to two control valve groups (60), (70), and also confluent selecting valve means (80), (90) adapted to introduce the pressure fluid sent into each control valve group into a working apparatus control valve in the other control valve group. The confluent selecting valve means (80) in a group to which a working apparatus control valve (62), which is required to compensate for an admission rate of the fluid, belongs cancels the confluent function in accordance with an operating signal for the same working apparatus control valve. This mechanism also has a means for limiting the spool stroke of a working apparatus control valve (160) in which a load varies, this means being adapted to introduce a discharged fluid from an actuator into the same actuator again when the load is small. This mechanism further has a sequence valve (170) adapted to operate a spool stroke limiting means (190) in accordance with a primary pilot pressure.
