Definitions

  • the invention relates to an internal combustion engine of the type according to the preamble of claim 1.
  • the invention has for its object to provide an internal combustion engine of the type described in the preamble of claim 1, in which - in particular also with acoustic decoupling of the cylinder head cover and cylinder head - the drive of the ancillary unit is as free of play as possible and nevertheless simple assembly thereof is ensured.
  • the construction according to the invention makes it possible to attach the auxiliary unit to the cylinder head before fitting the cylinder head cover and to keep the drive connection between the valve train and the drive of the auxiliary unit largely free of play. Then the cylinder head cover can be simply slipped over the auxiliary unit, with only a part of the same, the z. B. carries a connector, protrudes from the cylinder head cover. The seal provided avoids metallic contact between the auxiliary unit and the cylinder head cover, which is particularly important when the cylinder head and the cylinder head cover are acoustically decoupled.
  • a development of the invention is characterized in which only a line connection protrudes through the cylinder head cover, the position of which has large dimensional tolerances is compensated for by the large-volume, rubber-elastic sealing ring.
  • a vacuum pump 3 is arranged in the valve chamber 1 in the cylinder head 2 of an internal combustion engine (not shown).
  • the vacuum pump 3 is designed as a diaphragm pump. It is firmly screwed to the cylinder head 2 and its tappet 4 is driven by an eccentric 5 of the camshaft 6. Part of the vacuum pump 3 protrudes through a through opening 7 in the cylinder head cover 8 to the outside. In the area of the passage opening 7, the vacuum pump 3 is provided on the circumference with a groove 9 in which an O-ring 10 is arranged. The O-ring 10 forms a seal between the edge of the through opening 7 and the vacuum pump 3.
  • the cylinder head cover 8 is supported on the cylinder head 2 by a circumferential seal 11 arranged in a groove and is connected to the cylinder head 2 via a vibration-insulated screw connection (not shown) attached.
  • the part of the vacuum pump 3 protruding through the through opening 7 has a connecting piece 12.
  • the vacuum pump 103 is designed as a vane pump and is likewise firmly connected to the cylinder head 102.
  • the vacuum pump 103 is driven by the camshaft 106 via helical gears 113 and 114.
  • the cylinder head cover 108 is provided with a bulge 115, at the highest point of which a through opening 107 is arranged.
  • a connecting piece 112 of the vacuum pump 103 projects through this through opening 107.
  • a large-volume O-ring 110 is arranged as a seal between the edge of the through opening 107 and the connecting piece 112, so that any vibration insulation that may be present between the cylinder head cover 108 and the cylinder head 102 is not impaired.
  • the vacuum pumps 3 and 103 are attached to the cylinder head 2 and 102, respectively. After mounting the vacuum pump 3 or 103 in the valve chamber 1 or 101, the cylinder head cover 8 or 108 can simply be put over. As a result, the cylinder head cover 8 or 108 can be easily removed for adjusting the valve clearance without the drive of the vacuum pump 3 or 103 or the vacuum pump 3 or 103 itself having to be released.
