Definitions

  • an oil separator is located in a front housing member.
  • An oil separating chamber which forms part of the oil separator, is connected to a discharge chamber defined at the back of a fixed scroll.
  • the oil separating chamber accommodates a cylindrical member, which forms part of the oil separator.
  • Refrigerant gas in the discharge chamber is introduced into the oil separating chamber.
  • Lubricant oil included in the refrigerant gas introduced into the oil separating chamber is separated from the refrigerant gas.
  • Cylinder bores 411 extend through the cylinder block 41. Each cylinder bore 411 accommodates a piston 49. The rotation of the swash plate 47 is converted to reciprocation of the pistons 49 by means of shoes 50. Thus, each piston 49 reciprocates in the corresponding cylinder bore 411.
  • a muffler 57 is formed on the circumferential surface of the cylinder block 41 and the circumferential surface of the front housing member 42.
  • the muffler 57 has a cylindrical portion 58.
  • the cylindrical portion 58 is formed integrally with the cylinder block 41.
  • the muffler 57 is connected to the discharge chamber 432 via a discharge passage 59.
  • the muffler 57 is connected to the control pressure chamber 421 via an oil passage 60.
  • a pipe 61 is accommodated in and fitted to the cylindrical portion 58.
  • the pipe 61 includes a nozzle 62, a restrictor 63, and a diffuser 64.
  • the nozzle 62, the restrictor 63, and the diffuser 64 are arranged in series in this order along a direction from the muffler 57 toward the outside of the compressor 44 via the interior of the cylindrical portion 58.
  • an introduction passage 621 in the nozzle 62, a restricting passage 631 in the restrictor 63, and a pressure restoring passage 641 in the diffuser 64 are connected in series in this order from the muffler 57 toward the outside of the compressor 44.
  • the inner diameter of the nozzle 62 gradually decreases from the end close to the muffler 57 toward the restrictor 63.
  • the refrigerant gas When refrigerant gas is discharged into the muffler 57 through the discharge passage 59, the refrigerant gas collides with the inner wall of the muffler 57, or the refrigerant gas changes the flowing direction and flows toward the cylindrical portion 58. Therefore, the lubricant oil included in the refrigerant gas is separated from the refrigerant gas.
  • the passage of refrigerant gas extending from the muffler 57 to the cylindrical portion 58 narrows in the cylindrical portion 58. This prevents lubricant oil from entering the cylindrical portion 58. That is, the cylindrical portion 58 functions as an oil separator, which separates lubricant oil from refrigerant gas.
  • the lubricant oil separated from the refrigerant gas is stored at the bottom of the muffler 57. Refrigerant gas in the muffler 57 flows to the external refrigerant circuit, which is not shown, through the pipe 61.
  • the fourth embodiment has the same advantages as the advantages (1-1), (1-4), and (1-5) of the first embodiment.
