  • Scroll compressor having stable back pressure chamber with sealing members
    Patent number: 11105332
    Abstract: A scroll compressor is provided, comprising: a compression mechanism comprising a non-orbiting scroll member and an orbiting scroll member, wherein the orbiting scroll member is axially displaceable between an engagement position and a disengagement position; a main bearing housing adapted to support the compression mechanism; a back pressure chamber formed between the orbiting scroll member and the main bearing housing, wherein the back pressure chamber is in communication with at least one of the compression chambers via a communication passage provided in the orbiting scroll member or the non-orbiting scroll member and is adapted to apply a back pressure to the orbiting scroll member to bias the orbiting scroll member toward the engagement position; and a first sealing means provided between the back pressure chamber and a suction zone of the compression mechanism and capable of maintaining sealing when the orbiting scroll member is axially displaced.
