FIELD: mechanical engineering; manufacture of engines; equipment for gas compressor stations.
SUBSTANCE: proposed method consists in supply of gaseous medium, for example working medium of thermal engine to packing chamber through near-axis hole; packing chamber rotates around axis in seal housing; gaseous medium rotating together with chamber is passed between separating walls of isolated sections from axis to periphery of chamber and is discharged from packing chamber through outlet holes located near separating walls in peripheral part of chamber. Packed gaseous medium is delivered to user via connecting passage. Packed gaseous medium is taken from packing chamber located near point of intersection of separating wall with peripheral part of chamber on side of surface of separating wall directed in way of rotation of packing chamber and is directed to discharge hole via packing passage along peripheral wall of chamber. Working packing chamber is made in form of hollow envelope mounted on shaft; it is mounted in housing for rotation about shaft axis; it is provided with inlet passage in its near-axis part, outlet holes in peripheral part, inner partitions forming passages communicated with inlet passage and with outlet holes of chamber. Cross-sectional area of inlet passage of chamber exceeds total cross-sectional area of outlet holes. Inner cavity of each section is provided with shielding wall forming packing passage for gas medium together with peripheral part of chamber; this passage is communicated with outlet hole of chamber section having inlet hole made in shielding wall near separating wall of section whose surface is directed in way of rotation of packing chamber.
EFFECT: increased degree of packing gaseous medium; enhanced operational and economical efficiency.
