Definitions

  • Fig. 2 shows a detail of a chain case of an internal combustion engine with a device arranged therein for venting of the crankcase.
  • Fig. 3 shows in axial section an embodiment of a cyclone for the device for venting a crankcase.
  • Fig. 4 shows a radial section through the cyclone of Fig. 3 and an upstream calming space.
  • housing 11 and the cyclone 6 partially in the chain case 9 are integrated, as shown in Fig. 3, 4.
  • the chain case 9 forms one half each of the calming space 1 and the cyclone space by corresponding shaping of its end wall.
  • the second half of the calming space 1 and the cyclone space is formed by a one-piece housing inner shell 17, which may consist of a low-cost material such as sheet metal or plastic, which on the inside of the.
  • Chain box 9 is secured by means of flanges 18.
  • the central outlet 7 of the cyclone 6 is clamped between the housing inner shell 17 and the chain case 9, see. Fig. 3.
  • an opening 19 is provided which receives an outwardly directed connection piece 20.
  • the return pipe 15 is inserted into a corresponding opening of the housing inner shell 17 at the lower end of the cyclone 6.
