SCROLL DISTRIBUTOR AND TURBINE HERETO Russian patent published in 2012 - IPC F01D9/02 F01D25/24 

FIELD: engines and pumps.

SUBSTANCE: turbine scroll distributor comprises case and connector. Said case completely covers the area around annular channel coiled around turbine rotor and cylindrical channel extending from annular channel to rotational axis to reach the rotor. Connector retains to case relative to retaining part to allow the case to expand and contract radially from rotational axis crossing its center. Said connector has ledge, slot and recess. Ledge is arranged on either case or retaining part to extends in one direction along radial line. Slot is made in another element. It is open in another direction along said radial line to extend in circumferential direction relative to rotational axis. Said ledge enters said slot. Said recess is composed by cutout in one wall that shapes slot in one direction along said radial line. Ledge penetrates through said recess in displacement along rotational axis relative to said wall.

EFFECT: decreased sizes, ruled out thermal stress and distortion of case shape.
