PURPOSE:To simplify the structure, make it compact, save energy, and improve efficiency by rotating multiple rotors, main and driven, fitted on the same shaft quickly or slowly via the respective variable-speed sprocket having a pair of eccentric shafts. CONSTITUTION:Main and driven rotors 1, 2 are inclined against an axis; if the angle is made small the compression ratio, i.e., sprocket variation, becomes large; and if the angle is made small the compression ratio becomes small. Power shaft sprockets 15, 16 are rotated at a fixed speed, and while they are rotated one rotation, intermediate shaft sprockets 11, 13 are rotated one rotation, slow-quick, thus when the power shaft is rotated two rotations, the rotors are rotated one rotation at a variable speed, slow-quick-slow-quick. Only sprockets 15, 16 for the main and driven rotors of the power shaft are fixed at a position rotated by 180 deg., the others are all made free, and the intermediate gear ratio is made 2:1. Next, the volume of individual chambers between the rotors is changed by the variable-speed rotation of the rotors, 8 times of compression and suction are repeated during one rotation of the rotors, thereby the structure can be made compact, energy is saved, and the efficiency can be improved.
