To efficiently assist air supply from a supercharger to an engine without using an auxiliary blower in a supercharger surplus power recovery device for an internal combustion engine.SOLUTION: A supercharger surplus power recovery device comprises: an internal combustion engine; a supercharger which is provided in the internal combustion engine; a first hydraulic pump which is coupled to the supercharger and rotationally driven by the supercharger and generates an oil pressure; a second hydraulic pump which is rotationally driven by rotating a crankshaft of the internal combustion engine and generates an oil pressure; and a controller which controls the actuation apparatuses in an electronic manner and controls the drive of the first hydraulic pump and the second hydraulic pump. In order to support the rotation of the supercharger, the controller performs assist control for defining the first hydraulic pump as a hydraulic motor, driving the hydraulic motor with the oil pressure generated by the second hydraulic pump, and driving the hydraulic motor with an oil pressure amount which is determined for each load rate of the internal combustion engine when driving the hydraulic motor.SELECTED DRAWING: Figure 1

    【課題】内燃機関の過給機余剰動力回収装置において、補助ブロアを用いることなく、過給機によるエンジンへの給気を効率よくアシストする。【解決手段】過給機余剰動力回収装置は、内燃機関と、前記内燃機関に設けられた過給機と、前記過給機に連結されて前記過給機により回転駆動されて油圧を発生させる第1油圧ポンプと、前記内燃機関のクランク軸の回転により回転駆動されて油圧を発生させる第2油圧ポンプと、前記作動機器を電子制御し、前記第1油圧ポンプ及び前記第2油圧ポンプの駆動を制御するコントローラと、を有する。前記コントローラは、前記過給機の回転を加勢するために、前記第1油圧ポンプを油圧モータとし、前記第2油圧ポンプで発生した油圧で前記油圧モータを駆動させ、前記油圧モータの駆動の際、前記内燃機関の負荷率毎に定めた油圧量で前記油圧モータを駆動させるアシスト制御を行う。【選択図】 図1
