Definitions

  • That configuration is the Invention particularly advantageous in which the third Area of conduction from a first pipe, which itself subsequent second area of the line from the gap between the first tube and a second, the first Pipe coaxial surrounding pipe and the first area of the Line from the space between the second pipe and a third tube coaxially surrounding the second tube is formed.
  • These three tubes can thus be interlocked be made that two in the direction of flow successive "siphon-like" flow reversals surrender. Real pipe bends that are relatively expensive are not necessary in this case.
  • the second tube and one molded onto one end of this tube Guide device on which at least one reversal the direction of flow of the refrigerant takes place are combined in one piece into a second insert.
  • the accumulator shown in the drawing includes a cup-shaped housing 1, which at its lower Front end is completed by a bottom 2.
  • the Floor 2 can be detachable and sealed or permanent on the Housing 1 attached, for example welded.
  • a first insert 6 is in the interior of the housing 1 arranged.
  • This includes an inner tube 7, which with communicates its lower end with the outlet 3, and an outer tube coaxially surrounding the inner tube 7 8, the annular space between the two Pipes 7, 8 closed at the bottom by a curved bottom 9 is.
  • the annular space between the inner tube 7 and the outer tube 8 communicate with the interior of the bottom of the floor 9 Housing 1 through one or more holes 10 in the bottom 9.
  • an annular, molded-on container 11 On the outer surface of the outer tube 8 is an annular, molded-on container 11 open at the bottom, a plurality in its upper annular end face of perforations 12 is introduced.
  • the container 11 is filled with desiccant 13 and down through an annular disk 14 provided with perforations 15 is closed. Between the desiccant bed 13 and the upper annular face of the container 11 and the lower washer 14 is a layer of felt 16 or 17 inserted.
  • the radially outer wall of the container 11 is located on the inner wall of the housing 1. Through this and through the engagement of the inner tube 7 in the bore of the inlet 3, the insert 6 is held radially. Between the washer 14 and the bottom 2 of the housing 1 a coil spring 18 tensioned which is the upper end face of the container 11 against a bead 19 in the lateral surface of the housing 1 presses.
  • a second insert 20 is with the one described above first insert 6 nested in the following way:
  • a tube 21, which is part of the insert 20, has one Diameter on that between the diameters of the inner Tube 7 and the outer tube 6 is located and coaxial this into the annular space between the inside Tube 7 and outer tube 8 is led from above.
  • the lower end of the tube 21 is in a certain Distance above the bottom 9 of the first insert 6 and is here by at least one wing-like rib 22, which is molded onto the inner tube 7 of the first insert 6 is supported and guided radially.
  • At least a similar wing-like rib 23 is on the top Added to the area of the tube 21 of the second insert 20, which on the inner wall of the outer tube 8 of the first insert 6 supports and in this way the second insert 20 in the upper area against the first Insert 6 centered.
  • Tube 21 is formed on a guide device 24.
  • This comprises a first, in cross section semicircular, gutter-like Annular surface 25, which the upper free edge of the overlaps the outer tube 8 of the insert 6.
  • a second in cross-section semicircular, channel-like ring surface 26 of the guide device 24 overlaps the upper free one Edge of the inner tube 7 of the first insert 6.
  • Refrigerant coming from the evaporator becomes the interior of the housing 1 supplied via the inlet 5. So far in this refrigerant still contain liquid components are collected in the lower area of the interior of the housing 1, occur via the perforations 12, 15 in the desiccant 13 and there from moisture (Water) freed.
  • the gaseous phase of the refrigerant comes from the upper area of the housing 1, guided through the annular surface 25 of the guide device 24, in the annular space between the outer surface of the tube 21 of the second insert 20 and the inner circumferential surface of the outer tube 8 of the first Insert 6 and flows down here.
