Claims (1)
作用させ、この信号圧に対抗するようスプールが
両端間段差部に制御圧を作用させ、スプールがこ
れら信号圧及び制御圧による力に応動して制御圧
を信号圧に応じた値に調圧するようにした制御圧
発生装置において、 前記スプールに貫通孔を形成して該スプールの

とを特徴とする制御圧発生装置。[Claims for Utility Model Registration] A spool is provided, a signal pressure is applied to one end of the spool, a control pressure is applied to a stepped portion between both ends of the spool to counteract the signal pressure, and the spool controls the signal pressure and the control pressure. In a control pressure generating device that adjusts the control pressure to a value corresponding to a signal pressure in response to a force caused by pressure, a through hole is formed in the spool so that the signal pressure is applied to the other end of the spool. A control pressure generating device characterized by being configured as follows.
