When the loop (2) is opened, the oil from the hydraulic pump (b) is returned to the oil tank a◆ via the oil passage g4 (2), and the supply to the cylinder chamber (4) is stopped. The ninth piston (3), which also stops the return of oil from the cylinder chamber (4), is fixed in that position.
The oil in (4) passes through oil passage (6)@- and shutoff 7 (
It flows to the oil tank a4 via the oil passage (2), then to the oil passage (2), then to the oil tank a4 (2), and then to the piston (3
) slides in the direction of arrow B. At this time, the oil flowing back to the oil tank a◆ flows while the flow rate is limited by the flow rate fi control valve 4, so the sliding movement of the piston (3) is gentle and the oil is returned to the oil tank a◆. Some of the oil that is
8) and flows into the cylinder m1(5), which has a negative pressure. In this way, the hydraulic cylinder (1) is activated, and the shutoff pulp is used to control the operation of the hydraulic cylinder (1). Pulp valves and flow rate control valves are used, but these control valves are built into the enlarged body of the control valve while being connected by an oil passage, and the body of the control valve is attached to the hydraulic cylinder (1). The necessary control valve can be installed within the small installation space of the door plate (on the main body). In addition, multiple control valves can be installed at once, and the hassle of piping between the control valves is eliminated, making installation extremely easy.In addition, various main bodies with different functions are available. If you do this, it will be easier to perform different operations with the same hydraulic cylinder (1).
