FIELD: creation of vacuum. SUBSTANCE: at ratio of area of minimum flow section of mixing chamber to area of minimum flow section of nozzle of from 10 to 200, magnitude angular and radial misalignment of active nozzle and mixing chamber ranges from 0.10 to 12 mm and from 2 to 5°30′; at ratio of area of minimum flow section of mixing chamber to area of minimum flow section of nozzle from 200 to 1600, magnitude of radial and angular misalignment ranges respectively from 0.14 to 25 mm and from 2,5 to 10°30′. EFFECT: enhanced operational reliability. 2 dwg
