Claims (1)
孔に挿入され作動時でバイパス通路を閉じ、かつシリン
ダ通路と供給通路またはシリンダ通路と戻り通路に内部
通路を介して接続可能にする横孔を有するプランジャを
備えた複合制御弁において、前記少なくとも一つのプラ
ンジャ孔には一方の供給通路を遮断し、反対側のみとし
た供給通路の環状室と、前記プランジャ孔に挿入された
プランジャには中立時でプランジャ孔により閉じ゛られ
、作動時で供給通路の環状室のみに開口する絞り孔と、
同絞り孔に軸方向通路を介して接続され内部通路および
バイパス通路の環状室に開口する横孔と、前記絞り孔と

御弁。The valve body has a plurality of parallel plunger holes, and when inserted into these holes, it closes the bypass passage when activated, and can be connected to the cylinder passage and supply passage or the cylinder passage and return passage via an internal passage. In a composite control valve equipped with a plunger having a horizontal hole, the at least one plunger hole has an annular chamber of the supply passage with one supply passage blocked off and only the opposite side, and a plunger inserted into the plunger hole. The plunger has a throttle hole that is closed by the plunger hole when in neutral state and opens only to the annular chamber of the supply passage when in operation;
A composite control valve having a horizontal hole connected to the throttle hole via an axial passage and opening into an annular chamber of an internal passage and a bypass passage, and a relief valve interposed between the throttle hole and the axial passage.
