ELASTIC CONIC PART FOR TIGHTLY SEALED STATOR, RESPECTIVE ENGINE AND METHOD OF FABRICATION Russian patent published in 2015 - IPC H02K5/128 

FIELD: engines and pumps.

SUBSTANCE: invention relates to devices and methods of chamber sealing with simultaneous keeping of integrity of the named chamber being impacted by thermal stress. The engine contains the housing with a cavity, the stator implemented with a possibility of attachment to internal part of the named cavity, the elastic conic part implemented with a possibility of attachment to the first end of the housing, the rigid conic part implemented with a possibility of attachment to the second end of the housing, the non-metallic part implemented with a possibility of attachment to elastic conic part and rigid conic part, and the rotor located in the named cavity and implemented with a possibility of rotation inside the stator. The named housing, elastic conic part, rigid conic part and non-metallic part form tight chamber which contains the whole stator. The tight chamber is implemented with a possibility of keeping of the cooling fluid medium providing stator cooling , and preventing the passing of the cooling fluid medium to the rotor.

EFFECT: reliability improvement.
