Description
2 メインポンプ
3 メインコントロールバルブ
4 再生用調整バルブ
5 コントローラ(制御手段)
Claims (1)
- コントローラからの指令により、油圧ポンプからシリンダに流れる油路(P-C)の油量とシリンダからタンクへ戻る油路(C-T)の油量を制御して、両油路(P-C),(C-T)の油量を絞ることができるコントロールバルブを備えるとともに、前記油路(P-C)の油圧を検出し、その検出値を基準にシリンダへの圧油量を制御させる油圧信号ラインを備え、且つ再生用調整バルブを有する再生回路を付加させた油圧回路における油量制御方法であって、
前記再生回路が再生状態となって、前記再生用調整バルブからコントローラに再生状態を示す信号が出力されたとき、コントローラが、再生油量に相当する油量を減少させる絞り指令を、前記コントロールバルブに対し出力することを特徴とする作業機械の油量制御方法。
