PURPOSE:To eliminate a conventional counter-balance so as to reduce the size by arranging a constant volume pump between the crankshaft of compressor and the drive shaft of an engine to be coupled coaxially while specifying the eccentric direction of the outer rotor of said pump. CONSTITUTION:A tubular shaft 6i to be arranged between a housing 1 is fitted rotatably to a drive shaft 1a to be coupled to the output shaft of engine, then the end section of said shaft 6i is coupled to one end of the crankshaft 6c of a compressor including a cylinder body 2 and a piston 3. A casing 6e having a circular hole 6f is formed at the end section at the shaft 6i side of the crankshaft 6c and contains an outer rotor 6b assembled with an inner rotor 6a rotatably, thus constructing a trochoid pump. The eccentric direction of the outer rotor 6b against the casing 6e is set to direct toward the top dead center when the piston 3 is at the top dead center.
