Definitions

  • the invention relates to a capacitor, in particular for a motor vehicle air conditioning system according to the preamble of claim 1 - known from DE-A 103 06 192.
  • the known from DE-A 103 06 192 capacitor has a collector arranged parallel to a collector, in which a filter and / or dryer cartridge is arranged and positioned by an annular retaining rib in the axial direction in the collector.
  • the retaining rib is elastically deformable and held in an annular groove of the collector so that the retaining rib and the annular groove form a snap or latching connection. It can not be ruled out that the known locking connection dissolves during assembly or during operation of the capacitor, so that the dryer and / or filter cartridge is no longer fixed in the collector and can not perform their function. The operation of the air conditioner can be affected.
  • the known collector has a releasable closure part, so that the dryer and / or filter cartridge after soldering of the capacitor mountable and interchangeable during operation for maintenance reasons.
  • the closure member is preferably formed as an axially movable sealing plug, which is fixed by a retaining ring in an axial direction (outward).
  • a sealing plug was known from DE-A 100 39 260.
  • the sealing plug has an axial mobility inwards, resulting in tilting of the sealing plug in the collector and thus possibly lead to leaks.
  • a similar design for a capacitor with integrated collector was known from DE-A 44 02 927.
  • a dryer / filter cartridge is arranged, which is fixed in the axial direction on the one hand by abutment at the bottom of the collector and on the other hand by abutment against a screw cap.
  • the dryer / filter cartridge is sealed by an attached to the cartridge sealing ring and a soldered to the collector ring seat between overflow, which establish a connection between the collector and an adjacent manifold. Due to the triple support of the dryer / filter cartridge in the collector (top, bottom and in the middle), the system is statically indefinite.
  • an annular stop is provided in the collector, on which the annular retaining rib of the dryer / filter cartridge is supported.
  • the dryer / filter cartridge is supported against the closure member, so that it is clamped between the closure part and stop on the collector.
  • a compression spring is arranged between the dryer / filter cartridge and the closure part, which at the same time compresses the granules in the cartridge via a movable cover.
  • the closure member is formed as an axially movable sealing plug, which is fixed via a retaining ring in an axial direction, ie outward, while at the same time in the axial direction is movable inwardly.
  • the sealing plug is immediately counteracted by the pressure spring after assembly pressed the retaining ring and thus can not move in the axial direction even when unpressurized collector or condenser. This has the advantage that the plug does not tilt in the collector and thus can cause no leakage.
  • the annular retaining rib is simultaneously formed as a sealant, for. B. by the interposition of a flat gasket.
  • Fig. 1 shows a perspective view of a dryer / filter cartridge 1, which is designed as a cage-like plastic insert and is substantially known from the aforementioned prior art.
  • the dryer / filter cartridge 1 is arranged in a collector 2 partially shown, which is formed in this area as a profile piece and partially with an adjacent, parallel collecting tube 3 is integrated.
  • Collecting tube 3 and collector 2 form two spaces through which a refrigerant flows, which chambers are connected to one another by overflow openings 4, 5.
  • the manifold 3 communicates with pipes, not shown, of a capacitor, also not shown, which is preferably used for a motor vehicle air conditioning.
  • the illustrated in the drawing hollow cylindrical part of the collector 2 is closed at the end by a sealing plug 6, which is fixed by a retaining ring 7 in the axial direction to the outside.
  • a sealing plug is known from DE-A 100 39 260.
  • the filter / dryer cartridge 1 has a circumferential, annular retaining rib 8, which rests on an annular stop 9 of the collector 2.
  • FIG. 2 shows the dryer / filter cartridge 1 and the collector 2 according to FIG. 1 in a longitudinal section.
  • collector 2 and manifold 3 are formed in this area as a one-piece profile piece, which (in the drawing) down in a tubular, dashed lines indicated collector 2 'and in a likewise shown in dashed collector tube 3' continues.
  • the annular stop 9 is fixedly connected to the collector 2, z. B. formed in one piece or used as an additional part, and thus forms a support bearing for the annular retaining rib 8 of the dryer / filter cartridge 1.
  • the interior of the cage-like sleeve of the dryer / filter cartridge 1 is filled with a dryer material, not shown in the form of granules and is after closed at the top by a first axially movable in the sleeve cover 10, on which a compression spring 11 is arranged.
  • a second cover 12 is arranged, which is supported against a pin 6a of the sealing plug 6.
  • the compressed compression spring 11 thus has the effect of compressing the granules, not shown, on the one hand via the cover 10 and, on the other hand, the plastic insert of the dryer / filter cartridge 1 via the retaining rib 3 against the stop 9 and the sealing plug 6 via the second cover 12 against the retaining ring 7 presses. This is fixed in its axial mobility and inward.
  • the Abst Reifenproung consisting of retaining rib 8 and stop 9, can simultaneously perform sealing function, z. B. by between two annular surfaces 8, 9 a (not shown) is inserted seal.
