  • the flow path is advantageously in one in the Housing insert used tube insert. This can be made of plastic inexpensively by injection molding getting produced.
  • the pipe insert is composed of two partial shells. their injection molding manufacturing is much easier than that of a one-piece tube insert; you will be simply attached to each other after separate manufacture, for example clipped.
  • FIGS. 1 and 2 The one shown here and overall with the reference symbol 1 marked accumulator comprises a housing 2, that from a housing part 2a open at the bottom and a lower housing part 2b attached to this is composed.
  • the upper housing part 2a has over the largest part of its axial extent an Cross section circular outer contour, however instructs its upper end wall has a rectangular cross section, massive projection 2c, in which an angled to an inlet opening extending from a side surface of the projection 2c 3 and a similarly angled one Outlet opening 4 is provided for the refrigerant are.
  • the connecting lines of the accumulator 1 can be attached two threaded holes in the projection 2c 5, 6 are introduced.
  • the lower housing part 2b is bulged down like a dome and with a kind of bayonet lock 7 on the open attached lower end of the upper housing part 2a.
  • the housing parts 2a and 2b with each other be welded.
  • a baffle insert 8 Inside the housing 2 are from the top below a baffle insert 8, a tube insert 9 and a desiccant insert 10, which will be described later Are intertwined.
  • baffle insert 8 in perspective or in plan view demonstrate. It comprises a cylindrical peripheral wall 11, whose outer diameter is dimensioned so that it is installed Condition on the inner surface of the upper part of the housing 2a is present.
  • the peripheral wall 11 runs in the lower Area of baffle insert 8 over the entire Circumference, i.e. over 360 °, while in the axially upper Area ends at two vertical wall sections 12a, 12b, which run off-axis and in the plan view of the figure 4 Separate two circle segments of different sizes. This is tantamount to saying that the wall sections 12a and 12b are aligned, but not in one Axial plane of the baffle insert 8 are.
  • the horizontal wall 13 of the baffle insert 8 is with a variety of sieve openings 14 provided in the manufacture of the baffle insert 8 injected with or formed in a sieve fabric can be either the horizontal wall 13 itself forms or on relatively large windows is placed in this horizontal wall 13.
  • the baffle insert 8 In the radially central area is the baffle insert 8 between the wall sections 12a, 12b below (see FIG. 1) opening dome-like inlet area 15 molded on the horizontal wall 13 adjacent side of the wall sections 12a, 12b above the horizontal wall 13 over a large area, by a sieve 17 covered window 16 in the interior of the Housing 2 opens.
  • the arrangement is such that the above the horizontal wall 13 of the baffle insert 8 lying interior area of the housing 2 from that in the Near the inlet opening 3 lying interior area of the Housing 2 through the inlet area 15 and the latter laterally outwardly projecting wall sections 12a, 12b of the Baffle insert 8 are separated.
  • the one above the horizontal wall 13 lying interior area of the housing However, 2 stands over the window 16 with the interior of the Inlet area 15 of the baffle insert 8 in connection.
  • the inlet area 15 of the baffle insert 8 is from an integrally molded, axially parallel outlet pipe section 18 crossed, the top something over the dome surface of the inlet area 15 protrudes and in assembled State inserted in a step of the outlet bore 4 is, as can be seen in Figure 1.
  • Peripheral wall 11 limited space is a helical, guide wall inclined to the axis of the housing 2 19 provided.
  • the guide wall 19 goes from the wall section 12a at an axial height that is almost the corresponds to the maximum height of the peripheral wall 11, and lowers spiral down to a point below the Wall section 12b lies at an axial height which in is close to the lower edge of the peripheral wall 11.
  • the guide surface 19 carries one on its upper side Many parallel, also spiral guide ribs 44th
  • baffle insert 8 The more precise function of the baffle insert 8 is explained below.
  • This tube insert 9 is for manufacturing reasons for two Partial shells 9a, 9b injection molded, but could in principle also be in one piece. Assembled has the tube insert 9 an approximately cylindrical outer contour with a rounded bottom. Through an inner partition 21 the interior of the tube insert 9 in an inlet area 22 and an outlet area 23 divided. The inlet area 22 and the outlet area 23 are at the bottom End of the tube insert 9 through a curved transition area 24 connected to each other, at its deepest Place a through hole 25 is provided.
  • the partition 21 By a corresponding shaping of the partition 21 is the Cross section of the inlet area 22 in the upper area 22a significantly larger than in the lower area 22b, where the cross section essentially with the cross section of the transition area 24 and the outlet area 23 coincides.
  • the partition 21 encloses one cavity 26 through which no refrigerant flows.
  • the tube insert 9 bears on its outer lateral surface a radial flange which is circular in the outer contour 27, the function of which becomes clear below.
  • the upper end portion of the tube insert 9 is like that Figures 1 and 2 can be seen in the baffle insert 8, in particular its inlet area 15, from below introduced and shaped that the upper inlet portion 22a of the tube insert 9 with the interior of the inlet area 15 of the baffle insert 8 and the outlet area 23 of the pipe insert 8 with the outlet pipe section 18 of the Baffle insert 8 communicates.
  • the tube insert 8 extends in the proximity of the lowest point of the lower part of the housing 2 B.
  • the desiccant insert 10 comprises an annular one Upper part 10a, the perspective in Figure 6 is shown.
  • This upper part 10a has an outer Cylinder wall 28, the outer diameter with the inner diameter of the upper housing part 2a, and an inner cylinder wall 29, the area on the The outer surface of the tube insert 9 rests on.
  • At her upper edges are the outer cylinder wall 28 and the inner cylinder wall 29 by an annular horizontal End face 30 connected together, which is a variety of slot-shaped through openings 31.
  • the slot-shaped through openings 31 are on four Areas divided by radial, none Slits having webs 32 are separated from each other.
  • the webs 32 carry in their radially outer area Lugs 33 which are dimensioned and shaped so that below them, the flange 27 of the tube insert 9 snapped into place can be, as shown in Figures 1 and 2.
  • the lower end of the upper part 10a of the refrigerant insert 10 is through the lower part shown in Figure 7 10b closed.
  • This has an annular Bottom 34 in which a variety of sieve openings 35 are provided. These sieve openings 35 are at Injection molded the lower part 10b.
  • a filter holder extends in one piece from the bottom 34 36 down, the four axially parallel struts 37 and a ring part connecting these at its lower ends 38 owns.
  • the four windows that face down through the Ring part 38, up through the bottom 34 and laterally are limited by the struts 37, are with a screen fabric 39 covered.
  • the bottom 34 of the lower part 10b the desiccant insert 10 can from below the upper part 10a inserted and there behind locking lugs 40 at the inner, lower end region of the outer cylinder wall 28 are locked.
  • In the assembled position of the Accumulator 1 is located on the outer edge of ring part 38 on a cylindrical inner wall area of the lower housing part 2a, whereby centering takes place.
  • the pipe insert penetrates 9 the entire desiccant insert when assembled 10 including the portafilter 16 from above down so that the lowest point of the pipe insert 9, namely the through hole 25, in a small amount Distance from the lower housing part 2b.
  • the annular interior 42 of the desiccant insert 10 is filled with a desiccant bed 43, which is only partially indicated in Figure 2.
  • the liquid phase of the refrigerant sinks in the annulus between the tube insert 9 and the inner wall of the Upper housing part 2a down and penetrates the annulus 42 of the desiccant insert 10, the refrigerant is freed from moisture in a known manner. It forms in the lower area of the interior of the housing 2 a "swamp" where it constantly boils. Possibly in machine oil contained in the liquid phase of the refrigerant passes through the sieves 39 in the portafilter 36 of the Lower part 10b of the desiccant insert 10 therethrough and gathers in a swamp in the bulged down Area of the lower housing part 2b.
  • Gaseous refrigerant which is below the horizontal wall 13 of the baffle insert 8, rises up and passes through the sieve openings 14. It continues to flow through the sieve 16 in the window 16 of the Inlet area 15 of the baffle insert 8 and from there into the upper inlet area 22a of the tube insert 9b. There the cross section of the upper inlet region 22a still the flow rate is relatively large of the gaseous refrigerant in this area 22a comparatively low. This reduces the risk that the gaseous refrigerant when entering the inlet area 15 of the baffle insert 8 liquid refrigerant entraining.
