Patent number: 6648617Abstract: The invention relates to a method for compressing a compressible medium, in which at least two displacement elements, each having at least one limiting face extending helically in the cross section, are orbited in relation to each other under formation of at least one chamber, the volume of the chamber being changed by the orbiting movement, performing a cycle with a suction phase, a compression phase and a discharge phase, the chamber being opened and forming a suction chamber during the suction phase. It is endeavoured to improve the thermodynamic conditions during compression of a compressible medium. For this purpose, for the duration of the suction phase, the suction chamber is reduced by a volume limiting element in such a way that at the end of the suction phase the chamber has a volume of at least 90% of a maximum volume appearing during the suction phase.Type: GrantFiled: January 24, 2002Date of Patent: November 18, 2003Assignee: Danfoss A/SInventors: Jürgen Süss, Leonid Paramonov
