摘要： A flow divider includes a spool for distributing fluid from a supply flow path to priority and surplus flow paths. First and second surplus restrictions vary flow rate in accordance with the movement of the spool and restrict the flow rate to the surplus flow path respectively from first and second supply passages. The second surplus restriction is formed to restrict the flow rate in at least two steps. The spool includes a cross-sectional area changing portion located at a position corresponding to the second surplus restriction. Therefore, the circuit structure is prevented from becoming complicated and the fluid force acting as a spool urging force is suppressed.

摘要： A lift control valve is switched based on the manipulation of a lift lever, so that a lift cylinder extends or retracts to move a fork, supported on a mast, to move up or down. A check valve, which is actuated with a pilot pressure, is placed between the lift control valve and the lift cylinder. A pilot pipe led out from a pipe directly coupled to an oil tank is connected to a port of the check valve. A tilt control valve is switched based on the manipulation of a tilt lever, so that a tilt cylinder extends or retracts to tilt the mast. An electromagnetic valve is disposed between the tilt cylinder and the tilt control valve. When values necessary to drive the fork are detected, a controller control the electromagnetic valve based on those values.

摘要： A hydraulic control apparatus 1 includes a switch valve 11, an adjustment valve 12, and a valve control device 13. The adjustment valve 12 has a fluid chamber 15, a valve body 14, and a back pressure chamber 17. A restrictor is formed between the valve body 14 and a wall defining the fluid chamber 15 and connects the cylinder line 32 to the switch valve line 33. The opening degree of the restrictor changes in correspondence with movement of the valve body 14. When the switch valve 11 is located at a neutral position or a supply position, the valve control device 13 applies the fluid pressure in the cylinder line 32 to the back pressure chamber 17. When the switch valve 11 is located at a drainage position, the valve control device 13 applies a pilot pressure lower than the fluid pressure in the cylinder line 32 to the back pressure chamber 17.

摘要： A flow rate switching type flow divider for distributing fluid from a pump to a priority flow circuit and a surplus flow circuit. A flow divider valve arranged along a first line includes a first restriction to restrict flow rate of the fluid from the supply flow path to the priority flow path. A switch valve is arranged along a second line that differs from the first line so as to communicate with the supply flow path through the flow divider valve at a location upstream from the first restriction. The switch valve switches an opening amount of a connection flow path that bypasses the first restriction and extends from the supply flow path to the priority flow path. The switch valve includes a second restriction arranged in the switch valve for restricting flow rate of fluid flowing through the connection flow path.

摘要： A hydraulic device for a forklift is disclosed. The forklift includes a tilting mast and a fork supported by the mast so that the fork is lifted and lowered. A tilt cylinder operates to tilt the mast by means of oil supplied by a tilt valve. A restricting valve is arranged in an oil passage connecting the tilt cylinder with the tilt valve. When the mast is tilted with the fork carrying an object and located higher than a predetermined reference position, the restricting valve closes the oil passage so that the angle of the tilting mast is limited. A check valve is arranged between the tilt cylinder and the restricting valve. The check valve blocks oil flow from the tilt cylinder to the restricting valve so that the position of the mast is maintained. This prevents unintentional movement of the mast.
摘要翻译：公开了一种用于叉车的液压装置。叉车包括倾斜桅杆和由桅杆支撑的叉，以便叉被提升和降低。倾斜缸用于通过由倾斜阀提供的油倾斜桅杆。限流阀布置在将倾斜缸与倾斜阀连接的油路中。当桅杆与携带物体并且位于高于预定基准位置的叉倾斜时，限制阀关闭油通道，使得倾斜桅杆的角度受到限制。在倾斜缸和限制阀之间设有止回阀。止回阀阻止从倾斜缸到限制阀的油流，从而保持桅杆的位置。这可防止桅杆的无意移动。
