Definitions

  • the invention relates to a valve cover with an all-round edge. on one elastomeric seal rests. for the cylinder head of an internal combustion engine operating in the area the sealing plane between the valve cover and the cylinder head is perpendicular to the edge itself extending semicircular recess (DE-A-35 12 713).
  • the cylinder head of internal combustion engines is usually so-called Sealed valve covers or valve covers, with an elastomeric seal in the Edge surface of the hood clamped or with the interposition of an adhesion promoter is sprayed directly.
  • Sealed valve covers or valve covers In internal combustion engines with overhead camshafts is on End region of the cylinder head on the side facing away from the camshaft drive semicircular hole arranged. This hole is for machining the holes of the Camshaft bearings are required and can be sealed using the elastomeric seal will.
  • DE-OS 38 31 413 discloses a rubber molded seal with a metallic Stiffening insert for use in internal combustion engines with overhead Camshafts.
  • the semicircular bore in the cylinder head is indicated by a Half-moon shaped piece filled. which is part of the cylinder head cover gasket is trained.
  • the invention has for its object a generic valve cover with regard to improve their function, while at the same time a simple and safe assembly process is guaranteed.
  • An elastomeric seal can be attached to the edge of the valve cover, the Thickness is carried out over the entire circumference. that even pressure over the extent is achievable.
  • the side wall can be designed as an additional sheet and the additional plate must be firmly connected to the valve cover.
  • This construction is suitable especially for valve covers. which are made from sheet metal in the deep-drawing process.
  • the Additional sheet metal can be screwed, welded or the like on the deep-drawn Valve cover must be attached.
  • Figures 1 and 2 is a preferably drawn from sheet metal valve cover 1 for the Shown (not shown) cylinder head of an internal combustion engine, the one all-round, angled edge 2 for receiving an approximately strip-shaped trained elastomeric seal 3 with a projecting sealing edge 4 for the Has seal between cylinder head and valve cover 1.
  • the edge 2 of the valve cover 1 In the area of the valve cover 1 in which the semicircular is after assembly Recess in the cylinder head. is the edge 2 of the valve cover 1 with a projecting side wall 5 engaging in the semicircular recess.
  • This side wall 5 is designed as an additional sheet 6.
  • the feast e.g. B. by welding or Like., Is connected to the edge 2 of the valve cover 1.
  • the edge 7 of the additional plate 6 is angled and forms a semicircular flange surface 8 which is at a distance from the Bore area of the semicircular bore in the cylinder head ends.
  • the Flange surface 8 continues the elastomeric seal 3.
  • the thickness of the seal 3 in this area and the thickness of the seal in the other areas on each other are coordinated or designed so that when tightening the (not shown) Fastening screws for the valve cover 1 uniform pressure is achieved everywhere.
  • the seal 3 can be glued to the edge 2 and on the flange surface 8 or be vulcanized. But it can also be sprayed on. In the latter case, as with Example shown here, the additional sheet 6 with an all-round sheath 9 elastomeric material.
