    • A pressure controlling valve is provided to miniaturize the structure but steadily generate a control pressure by simplifying an oil pressure circuit for generating the control pressure because a control valve is not only necessary by operating an output pressure to a first spool selectively as a feedback pressure, but also excessive thrust is not necessary by generating the output pressure without the feedback pressure supplied to the first spool. A pressure controlling valve comprises a sleeve(62) composed of an input port(p1), an output port(p2), and drain ports(p4 - p6); a linear solenoid unit(11) generating a thrust; a first spool(26) disposed in the sleeve to freely advance and retreat and given the thrust transmitted to adjust an input pressure into the input port and to output an output pressure from the output port; and a second spool(27) disposed in the sleeve to freely advance and retreat and given the thrust transmitted to operate the output pressure, selectively as a feedback pressure, to the first spool.
    • 提供压力控制阀以使结构小型化,但是通过简化用于产生控制压力的油压回路来稳定地产生控制压力,因为不仅通过选择性地将第一阀芯的输出压力作为反馈压力来操作控制阀, 而且在没有提供给第一线轴的反馈压力的情况下产生输出压力也不需要过大的推力。 压力控制阀包括由输入端口(p1),输出端口(p2)和排出端口(p4-p6)组成的套管(62); 产生推力的线性螺线管单元(11) 设置在所述套筒中以自由前进和后退并且给出传递的推力以将输入压力调节到所述输入端口中并从所述输出端口输出输出压力的第一阀芯(26) 以及设置在所述套筒中以自由前进和后退的第二卷轴(27),并且将所述推力传递给所述第一卷轴,以将所述输出压力选择性地作为反馈压力操作。
