    Abstract: An electromagnetic switching valve, for which the maximum opening is set to be small, is disposed on piping between a lift cylinder and a hydraulic pump motor. A pilot check valve, for which the maximum opening is set to be larger than the electromagnetic switching valve, is disposed on piping, different from the piping, between the lift cylinder and the hydraulic pump motor. In addition, during lowering operations, first, the electromagnetic switching valve is opened, and then after the same is opened, the pilot check valve is opened after a prescribed time has passed. Thus, the shock generated when lowering an object to be raised/lowered is reduced and a fork is operated quickly.

    Abstract: A hydraulic control apparatus 1 includes a switch valve 11, a valve support chamber 35, a flow control valve 12 movable within the valve support chamber 35, an on-off valve 13 movable within the communication path chamber 12a, and a valve control device 14. The flow control valve 12 has a communication path chamber 12a and a back pressure chamber 12d. The on-off valve 13 is capable of opening and shutting off a communication path X between a cylinder line 32 and a switch valve line 33. A restrictor is formed between the flow control valve 12 and a wall defining the valve support chamber 35. The restrictor connects the cylinder line 32 and the communication path chamber 12a to each other. The opening degree of the restrictor is changed in correspondence with movement of the flow control valve 12. When the switch valve 11 is located at the neutral position or the supply position, the valve control device 14 applies a fluid pressure in the cylinder line 32 to the back pressure chamber 12d for urging the on-off valve 13 in a direction for shutting off the communication path 12a. When the switch valve 11 is located at the drainage position, the valve control device 14 applies a pilot pressure lower than the fluid pressure in the cylinder line 32 to the back pressure chamber 12d, thereby moving the on-off valve 13 in a direction for opening the communication path X.

    Abstract: A valve arrangement including a release valve. The valve arrangement controls a piston of a cylinder assembly upon interruption of a source of fluid pressure supplied to the cylinder assembly, the cylinder assembly including a first port and a second port and slideably housing the piston for movement between an extended position and a retracted position. The valve arrangement includes a valve assembly in fluid communication with the source of fluid pressure and with the first port and the second port to control fluid flow between the source of fluid pressure on the first port and between the source of fluid pressure on the second port, and a release valve fluidly connected to the first port and to the second port, the release valve being operable to control flow of fluid from the first port and from the second port. The release valve includes a release valve body including a release valve bore in fluid communication with the first port and with the second port, the release valve body further including a release valve seat, and a release valve member movable between a closed position, in which the release valve member engages the release valve seat to prevent fluid flow through the release valve bore, and an open position, in which fluid flows from at least one of the first port and the second port and through the release valve bore. Preferably, the release valve includes a manually engageable portion operable to allow fluid flow from the first port and the second port.

    Abstract: A flow control apparatus for a fluid cylinder for a workpiece holder includes a flow restricting member and a flexible sealing member. The flow restricting member defines a first passageway and a sealing surface. The flexible sealing member is positioned around the sealing surface. A second passageway is defined between the sealing member and a sealing surface of the flow restricting member when the sealing member is pushed away from the sealing surface in response to fluid flow in a first direction. When fluid flow is applied in the opposite direction, the sealing member moves to engage the sealing surface to substantially limit or preclude fluid flow between the sealing member and the sealing surface in the second direction. The fluid flow in the second direction is thus restricted to flow through the first passageway, thereby slowing or controlling the flow in the second direction.
