PURPOSE:To prevent unbalancing of the innertia force of a moving part and production of uneven torque, by a method wherein, in a volume type prime mover, a projection type rotor, having projections each formed with a lateral columnar, and a recess type rotor, having recesses each having width equal to the size of the columnar, are provided. CONSTITUTION:A projection type rotor, having projections each formed with a lateral columnar, and a recess type rotor, having recesses each having width equal to the size of the columnar, are provided. The volume of a space produced when the two rotors are engaged with each, is decreased and increased again during a time in which the two rotors are disengaged from each other. A suction port 1 is located in a position, allowing the suction port to face the space, at a point of time when the volume of the space is reduced to a minimum value. When working fluid having a proper pressure is poured through the suction port 1, the volume of the space is increased and the rotors are rotated. The working fluid flows out through discharge ports 2-4. This prevents unbalancing of the inertia force of a moving part and production of uneven torque. |
