Abstract

　圧力検出手段３０によって検出される第３ポンプの吐出圧Ｐｄ３に基づいて前記第１、第２ポンプの補正トルク量を出力するトルク補正量出力部Ｔ２と、前記指令手段によって指令される原動機の目標回転数に基づいて前記第１、第２ポンプの基準トルク値を出力する基準トルク出力部Ｔ１と、それらの出力値Ｔｄ３，Ｔｅに基づき、前記第１、第２ポンプの入力トルクを増トルクするようなトルク制御指令圧を演算し、第１、第２ポンプ用レギュレータの可変機構に外部指令圧として供給して、第１、第２ポンプの入力トルクが必要以上に減トルクされないようにする。これにより、３つの可変容量型油圧ポンプを用いたときに、そのうちの１つの油圧ポンプの吐出圧を減圧弁により減圧し、その圧力でその他２つの油圧ポンプの入力トルクを減トルクしても、エンジン出力を有効活用でき、作業量の低下を招くことがない。
