PURPOSE:To prevent the lubricating oil of an engine from entering a compressor by connecting the piston of said compressor to a rod which is connected to the piston of said engine and extends upward from said piston through a combustion chamber. CONSTITUTION:The cylinder 2 of a compressor is provided above the cylinder 1 of an engine. A rod 5 which extends upward from an engine piston 3 through an engine combustion chamber 24 is connected to the bottom part 7 of a compressor piston 6. Although a lubricating oil 19 is fed to the engine, there is little possibility that the oil enters the inside of the cylinder 2 of the compressor along the rod 6.
