    • The present invention provides a flushing circuit for a hydraulic cylinder drive circuit, by which the flushing of the circuit is conducted while protecting precision apparatuses of a control valve unit, because the flushing of a reciprocating hydraulic cylinder and its drive circuit is conducted while bypassing the control valve unit.
      In a hydraulic oil supply/discharge circuit connecting a tank of hydraulic oil, a hydraulic pump generating pressurized hydraulic oil, and a hydraulic cylinder with one another, a control valve unit in which at least a direction switching valve is provided in the vicinity of the hydraulic pump and the oil tank and a multifunction valve having a bypass circuit in the vicinity of the hydraulic cylinder are provided, and a bypass circuit bypassing the control valve unit is provided to branch from a hydraulic oil supply/discharge circuit between the multifunction valve and the control valve unit. At the time of the flushing of the hydraulic cylinder and the hydraulic oil supply/discharge circuit, contaminated hydraulic oil returns the tank without passing through the control valve unit, with the result that the control valve unit is protected from the contaminated hydraulic oil.
    • 本发明提供了一种用于液压缸的驱动电路,通过该电路的冲洗,同时保护控制阀单元的精密仪器中进行冲洗电路中,由于往复式液压缸的冲洗和其驱动电路导通,同时绕过 控制阀单元。 在将液压油箱,产生加压液压油的液压泵和液压缸相互连接的液压油供给/排出回路中,在控制阀单元中至少设置有方向切换阀, 液压泵和油箱以及在液压缸附近具有旁路回路的多功能阀,旁通回路的旁通回路设置成从多功能阀和液压泵之间的液压油供给/排出回路分支出来, 控制阀单元。 在冲洗液压缸和液压油供给/排出回路时,被污染的液压油在不经过控制阀单元的情况下返回油箱,从而防止控制阀单元受到污染的液压油的影响。
