The turbocharger excess power recovery device for an internal combustion engine includes a turbocharger (5) which supplies charge air to the internal combustion engine (1); a first hydraulic pump (10) which is a fixed- displacement hydraulic pump coupled to a rotating shaft of the turbocharger; a second hydraulic pump (11) which is a fixed-displacement hydraulic pump coupled to a crankshaft (2) of the internal combustion engine; a hydraulic circuit (20) which connects the first hydraulic pump to the second hydraulic pump; a third hydraulic pump (12) which is a variable-displacement hydraulic pump that is provided for the hydraulic circuit to make mutual hydraulic flow rate adjustments between the first hydraulic pump and the second hydraulic pump; and an electric motor (13) which is coupled to a rotating shaft of the third hydraulic pump and rotates together with the third hydraulic pump. |
