PURPOSE:To enable the use of high temperature high pressure gas and increase thermal efficiency as high as possible, by annularly arranging an even number of at least four operating gears, hollowly forming a shaft of the operating gears and communicating the shaft to a lubricating oil pump. CONSTITUTION:Six operating gears 1-6 are annularly arranged and mutually meshed. Exhaust and intake are operated in a meshed part G1 meshing toward the inside, while compression, explosion and expansion are operated in a meshed part toward the outside. A shaft 61 of the operating gear is formed to a hollow 62, and an oil hole 63 is opened to an end face of the shaft to communicate the hollowed part 62 to a lubricating oil pump 55. In this way, the operating gears can be cooled by supplying lubricating oil, and high temperature and high pressure gas can be used to increase thermal efficiency as high as possible and reduce fuel consumption. |
