FIELD: turbomachine engineering. SUBSTANCE: fixed disk and disk movably mounted on the shaft are positioned inside the housing having the inlet and outlet branch pipes. The sides of the disk facing each other is provided with alternating hollows and projections which define working passageways. The surfaces of the hollows and projections at each section perpendicular to the radius are bounded by arcs of circumferences radii of which increase from the periphery to the center to define radial working passageways.
