A rotary machine including an outer housing, and a cam-shaped rotor mounted within said housing for rotation about an axis coincident with the axis of the housing with two sealing members for the rotor equally supported at diametrically opposed positions within the housing for movement toward and away from the peripheral surface of the rotor and in at least close sealing proximity with the adjacent surface of the rotor during at least part of the rotation of the rotor, the lobe portion of the rotor being at least in close sealing proximity with an adjacent inner surface of the housing, an inlet passage through said rotor and opening through the surface thereof on one side of said lobe portion, an exit passage also passing through the rotor and opening through the surface thereof on the other side of said lobe portion, said inlet and exit passages communicating with ports for admitting working fluid to, and exhausting working fluid from, said rotor. Also disclosed is a twin rotor arrangement in which two rotors are supported within the housing on a common support shaft and separated by a partition wall with the respective lobe portions and sealing members being at diametrically opposed positions within the housing to dynamically balance the forces within the machine. |
