Definitions

  • Fig. 6 shows the flow of the refrigerant with the intake valve closed, that is located behind the suction port 24 of the suction muffler 16 on the piston side facing the valve plate, by means of arrows.
  • Suction tube 17 encloses along a section.
  • the cold refrigerant flowing out of the suction pipe 17 flows into the section of the jacket tube 34 forming the filling volume 20 of the suction muffler 16 during the suction cycle.
  • the filling volume 20 of the suction muffler 16 can no longer receive any further refrigerant from the suction pipe 17 due to the closed suction valve Therefore, the refrigerant flows back into the compensating volume 21, which is likewise formed by a section of the jacket tube 34, and displaces the warm refrigerant contained therein via the compensation opening 23 into the interior of the compressor housing 1.
  • the Fig.14 to 18 show different mounting options 30 between elastic connecting means 19 and suction tube 17, which can be designed either as a toothing ( Fig.17, Fig.18 ) or as arranged on the elastic connecting means barbs ( Figure 16 ) or as simple paragraphs ( Fig.14, Fig.15 ).
