FIELD: machine building.
SUBSTANCE: invention relates to machine building field, particularly to volumetric rotor-type machines. Volumetric rotor-type machine contains casing, working surface of which is surface of revolution, rotor with working surface of revolution, installed in casing with ability of rotation, circular working cavity, formed by working surfaces of casing and rotor, "c" - shaped separator, installed in circular working cavity angularly to plane of rotor rotation, in part of working cavity by rotating running of rotor, fixed stationary to casing, windows of inlet and outlet of working body. Outlet window is separated from inlet window by separator. On working surface of rotor it is implemented at least one groove angularly to plane of rotation of rotor, exceeding angle of slope of separator, for instance lengthwise geometrical pivot pin of rotor. In each groove of rotor it is installed piston with ability of overlapping of working cavity and execution of rotator oscillations in plane of groove. Piston is implemented in the form of at least part of disc, and in each piston it is at least one slot for passing of separator, facility for overlapping of piston slot on force-feed section of machinery.
EFFECT: providing of continuous delivery at whole cycle of operation and favourable aggregation of separate stages into multistage aggregation.
