ROTARY MACHINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in reversible pulsationless high-pressure rotary machines which can operate as pumps or as engines. Proposed machine contains working chamber and additional working chamber, separating junctions and adjusting members. Adjusting members are mechanically interconnected so that displacement of one adjusting member leads to displacement of other adjusting member. Working spaces of both working chambers located axially opposite to each other are interconnected by channels. Mechanism setting axial relative positioning of displacers provides sliding with each adjusting member of at least one of displacers. EFFECT: enlarged operating capabilities of rotary machines of proposed type, improved operating characteristics. 2 cl, 6 dwg
