ABSTRACT:
The rotary machine comprises: a stationary housing having an interior profile defining a monolobic configuration; a rotary cylindrical body arranged eccentrically in the housing and including a series of arc-shaped segments mounted in circular alignment in the housing and spaced to define therebetween a series of radial slots; interfitted double vanes slidably received in the slots; and counterweight means mounted in the body and disposed adjacent each blade portion of the double vanes; during rotation of the body, the counterweight means at one end of one double vane gradually opposes the movement of the said one double vane while, simultaneously, at the opposite end of the same double vane, the counterweight means are gradually removed from this opposite end of the blade portion whereby the centrifugal forces acting on the double vanes are balanced and vane pressure on the housing is minimized. The disclosure also describes the rotary machine incorporated in a motor, pump, transmission, differential and brake.
