Definitions

  • the invention relates to a housing for a Kurbelgekoruseentlwestungsvorrich ⁇
  • KGE system Crankcase ventilation system
  • connection lines in the given space are tively adapted to the connection lines in the given space
  • housing variants are on separate
  • the object of the invention is therefore, on the housing of a Kurbelgekoruseentlüf ⁇
  • a is provided in a parting plane between the housing parts receiving groove for the sealing ring on the locking ring shoulder and / or on the locking receiving shoulder. This makes it possible in particular, vorzumontieren the sealing ring before joining the housing parts by the sealing ring is inserted into the receiving groove.
  • a receiving space for the sealing ring is created with a defined geometry.
  • the bottom of the receiving groove is set obliquely with respect to a parting plane between the housing parts.
  • a similarly oriented inclined surface that is, an annular surface which is aligned substantially parallel to the groove bottom of the Dichtungsfactnut.
  • the further advantage of the oblique design of the groove base is that the transition from the locking ring sales or Rastworkabsatz can be pulled down to the normal wall thickness of the module, since a sufficiently large wall thickness remains above the Dichtungsingnut to the strength of the corresponding wall area guarantee.
  • the locking tab and the locking receptacle paragraph go to the prepared locking connection flush with each other, so no Supernatants or other points of attack are given, where a levering of the housing connections would be possible. It is thus avoided that the user is intervened in the construction of the housing of the crankcase ventilation device.
  • Fig. 1 is a crankcase ventilation housing in perspective, sectional view
  • Fig. 1 shows a crankcase ventilation device with a housing 10, which comprises in the illustrated embodiment, at least one upper housing part 1 with an inlet nozzle 3, a lower housing part 4 and a housing cover 2 with an outlet 2.2.
  • the upper housing part 1 terminates in a locking ring shoulder 7.
  • the lower housing part 4 opens at a locking receiving shoulder 8.
  • the paragraphs 7, 8 are profiled uniformly along the circumference, that is, there are no profile interruptions, cuts or the like.
  • the lower housing part 4 and the upper housing part 1 can take any desired angular positions to each other before they are then connected to one another via the latching connection.
  • Fig. 2 shows as an enlarged detail Il of the marked in Fig. 1 with a circle section, the junction between the housing parts 1, 4.
  • the wall of the lower housing part 4 extends in the region of the Rastworkabsatzes 8 so far that a sufficiently wide Dichtungsingnut 8.3 is to be arranged between an inner boundary web 8.4 and an outwardly widening wall section 8.2.
  • a groove bottom 8.3 is aligned at an acute angle with respect to a parting plane T to cause a radially outwardly acting force component during the joining, which leads to a bias of an inserted into the Dichtungsfactnut 8.3 sealing ring 9.
  • the wall section 8.2 is also designed as a ramp for an opposite locking ring shoulder 7 and opens at an overhang before an undercut 8.1.
  • the wall in the region of the locking ring paragraph 7 initially passes into an inclined surface 7.1, which is approximately parallel to the groove bottom of Dichtungsfactnnut 8.3.

Abstract

L'invention concerne la fabrication d'un boîtier (10) pour un dispositif (10) de ventilation de carter de vilebrequin comprenant au moins un raccord (3) d'entrée et un raccord (2) de sortie décalé dans le sens axial par rapport à celui-ci et prévoit, pour pouvoir adapter facilement et à moindre coût la position angulaire des raccords (2, 3) l'un par rapport à l'autre, que le boîtier (10) de ventilation de carter de vilebrequin est divisé en au moins une partie (4) inférieure de boîtier et une partie (1) supérieure de boîtier sur laquelle est façonné le raccord d'entrée (3). Selon l'invention, la partie (4) inférieure de boîtier et la partie (1) supérieure de boîtier sont reliées ensemble par le biais d'une liaison à encliquetage annulaire.
