Title:
SUPERCHARGER SURPLUS POWER RECOVERY DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/175194
Kind Code:
A1
Abstract:
[Problem] To dramatically improve power transmission efficiency and avoid having to install redundant hydraulic devices. [Solution] The present invention is equipped with: an internal combustion engine (1) for which operation devices (51) for operating the engine are electronically controlled by means of hydraulic pressure; a supercharger (5); a first hydraulic pump (10) that is rotationally driven by the supercharger, thereby generating hydraulic pressure; a hydraulic mechanism (20); a second hydraulic pump (11) that is rotationally driven by the power source (1) and supplies hydraulic pressure to the operation devices; a controller (50) for controlling the operation of the first hydraulic pump, the second hydraulic pump, and the hydraulic mechanism; first oil passages (21, 22, 23) for supplying hydraulic pressure from the second hydraulic pump to the operation devices; and second oil passages (26, 27, 22, 23) for supplying hydraulic pressure from the first hydraulic pump to the operation devices. In addition, the present invention is equipped with third oil passages (26, 27, 22, 21) for supplying hydraulic pressure from the first hydraulic pump to the second hydraulic pump, and fourth oil passages (21, 22, 27, 26) for supplying hydraulic pressure from the second hydraulic pump to the first hydraulic pump.
