Abstract

　エンジンによって駆動される油圧ポンプと、油圧ポンプから吐出された圧油が供給される油圧アクチュエータと、各油圧アクチュエータを操作する操作レバーと、各操作レバー手段の操作量を検出する検出手段と、操作レバーの操作量をもとに油圧ポンプの目標流量を演算する目標流量演算部（５０）と、前記目標流量に応じて、エンジンの第１の目標回転数を演算する第１の目標回転数演算部（６１）と、油圧ポンプの負荷圧に応じてリリーフ時におけるエンジンの最大目標回転数を制限するリリーフ時ポンプ出力制限値演算部（５００）および第４のエンジン目標回転数演算部（６３）と、前記第１の目標回転数および前記第４のエンジン目標回転数のうちのいずれか低い目標回転数に一致するように、エンジン回転数を制御する回転数制御手段とを備え、リリーフ時などの高負荷時におけるポンプ効率およびエンジン効率を高める。
