Abstract

PURPOSE:To offset centrifugal force of each rotor bearing with that of a balance weight as well as to aim at reduction in the extent of bending moment in an eccentric shaft by setting up the balance weight in the position decentered from the shaft center at the opposite side to each eccentric direction between two rotor bearings. CONSTITUTION:In an engine body 1, an eccentric shaft 27 is pierced through over an interval between side housing 2 and 3 at both sides. And, each of three rotors 33, 34 and 42 is rotatably supported on each of the rotor bearing 30, 31 and 41 formed in the eccentric shaft 27. And, the eccentric shaft 27 is supported each of three main bearing 12-14 installed each in three side housing 2-4 at both sides and the intermediate part. In this structure, in the eccentric shaft 27 in a position corresponding to an intermediate housing 5 between second and third cylinders C2 and C3 where a bearing part is not formed, there is provided with a balance weight 50 at the decentered position.
