Definitions

  • the present invention aims to remedy these drawbacks in particular by proposing an improved recovery and recycling device and making it possible to avoid mounting a sheet of complex shape in the settling chamber, and which is consequently less expensive and technically simpler. With such a device, it is also possible to avoid any vibration generating noise during engine operation.
  • the foundry of the cylinder head has a wall located in the joint plane of the cylinder head and of the cylinder head cover, which wall constitutes the bottom wall of the chamber above and is pierced with openings for the passage of unburnt combustion gases and for discharging the oil.
  • the foundry of the cylinder head cover forms a substantially U-shaped cross section conduit whose end of the branches bears on the aforementioned bottom wall, and which extends in a closed loop in substantially the joint plane of the cylinder head and the cylinder head cover.
  • the aforementioned conduit comprises baffles coming from molding with the cylinder head cover.
  • Figure 2 is a partial sectional view of the engine, along a sectional plane passing through the axes of the rods of two valves of a cylinder of this engine.
  • FIG. 5 is a sectional view of the engine, along the line V-V of FIG. 4.
  • the cylinder head cover 6 has an upper wall 16 from which two substantially parallel walls or partitions 36 project.
