A positive-displacement rotary machine comprises a housing a rotor installed in the housing with the a capability of rotation, a separator installed in the housing, having a guide part with a hole for the rotor; a piston installed in the a groove of the rotor with the a capability of making rotary oscillations relative to the rotor around an axis that intersects the an axis of rotation of the rotor, having at least one slot into which the guide part of the separator enters, a sphere-like working cavity formed around the rotor, which the guide part of the separator, during interaction of the hole with the rotor, divides into chamber-forming cavities of variable cross section, each of which is divided by the piston into working chambers. There is a passage for the a working fluid that permits the working thud to bypass the minimal cross section of the chamber-forming cavity; and input and output ports of the working fluid.
