摘要

FIELD: engines and pumps.;SUBSTANCE: invention relates to compressors or engines. Double-auger unit of movable working chambers of mechanical compression or using pressure of liquid and/or gaseous working body comprises one auger integrating one lengthwise end face of helical wall with bottom, and another auger integrating opposite end face of the like helical wall with bottom. Movable augers are driven by clamping device and/or converting drive. Augers feature spherical or flat shape. Helical walls together with bottoms of both augers are displaced through half the pitch of generating spiral minus sum of thickness of both helical walls. Space between bottoms of both augers is separated by helical walls into tight chambers arranged on both sides of either helical wall. Helical wall of one auger can roll in whatever direction and slide along two helical surfaces of helical wall of the other auger to vary volume of chambers formed and disappeared in space between bottoms of augers.;EFFECT: reduced friction of working surfaces.;24 cl, 34 dwg
