FIELD: hydraulic and pneumatic machine engineering. ^ SUBSTANCE: invention can be used as pump, compressor or engine. Proposed gyrator machine has stator, screw rotor and holder. Rotor is placed in holder forming working chambers between mated surfaces, and holder is installed for rotation inside stator forming working chambers between their mated surfaces. Area of through section between rotor and holder and between holder and stator is made variable along longitudinal axis of machine. Rotor and holder are made for displacement under axial force to press rotor, holder and stator to each other, with provision of automatic taking up of slacks, if formed. Rotor is spring-loaded relative to stator. Clearances formed between rotor and holder and between holder and stator are compensated. Clearances should be compensated also if gyrator machine reverses, i.e. when medium moves in opposite direction. ^ EFFECT: improved operation reliability. ^ 4 dwg |
