Definitions

  • the invention relates to a device consisting of a cylinder head and its cover intended to be mounted on the engine block of an internal combustion engine.
  • the device according to the invention which is consisting of a cylinder head and its lid intended for be mounted on the engine block of a combustion engine internal is characterized in that the cylinder head and its cover, integrated into these, of first passages to ensure, for lost gases loaded with oil and from combustion and compression, their circulation into a room top of camshaft housing breech of the engine and in which the gases are partially de-oiled by decantation, the oil decanted back down in the oil core of the cylinder head through holes in the part separating said core from the housing chamber of the camshaft, a pipe of passage in the cylinder head cover ensuring the circulation of partially de-oiled gases from the chamber housing the camshaft through a chamber the breech cover having therealong alternately opposite walls defining baffles or the like until completely de-oiled by decantation the gases arriving on a bottom wall of the cylinder head chamber located downstream of the baffles, decanted oil passing through this bottom wall to fall back into the chamber of housing of the camshaft, and in that the cover of cylinder head
  • Figure 1 there is shown generally a view from above of the device according to the invention which has a cylinder head 1 and its associated plate 7. This figure thus described is in fact given only for show matches with cross sections Figures 2 to 8 and is therefore not further described.
  • a passage duct 13, also visible at the FIG. 3, formed in the breech cover 14 enables a rise according to the arrows F4 of the gases partially deoiled and brought into a settling chamber 15.
  • This settling chamber formed in the lid head 14 has, as seen in Figure 3, alternately opposite walls defining baffles or the like 16 forming along this chamber a kind of labyrinth.
  • the passage of gases according to the arrow F5 in the settling chamber 15 allows these gas, following the path of this kind of labyrinth, to be completely deoiled, the oil being deposited then in the bottom 17 of the cylinder head cover 14 downstream of baffles 16 and passing through the volume of chamber 9 of Figure 2 by orifices 18 formed in this bottom.
  • the deoiled gases cross, according to the arrow F9, a bore 23 formed in the cylinder head 1 and pass into a channel 24 by following the arrow F10 to feed a hollow foundry cavity 25 formed by coring directly to the molding of the engine block in accordance with first method of forming part of the channels according to the invention and which is illustrated in FIGS. 4 and 5.
  • the distribution of gases deoiled is done in intake ducts 27 in from the cavity 25 of Figure 4 and, according to Figure 7, this distribution is done in ducts intake 27 from the bore 26 of FIG.
  • the distribution is then ensured, according to the method chosen, either by the length of the borehole 26 or by the the length of the gross foundry cavity 25 and by orifices or channels 29 (FIGS. 5 and 7) opening downstream of the intake valve 31.
  • FIGS. 7, on the one hand, and 8, on the other hand, which both correspond to the audit second process, show two different implantations of the part of the channels for supplying the de-oiled gases level of the intake valve 31.
  • Figure 7 shows an implementation of the canal "behind" the inlet valve 31, that is to say in downstream of the intake duct 27.
  • This implantation corresponds to the preferred embodiment.
  • the area on which the gases deoiled from channel 29 downstream of the valve intake 31 is a zone with greater turbulence and allows a better distribution of gases in the air intake.
  • Figure 8 shows on the contrary an implementation of channel "in front of" the intake valve 31.
  • This channel is here referenced 32 and corresponds to channel 29 of FIG. by being in correspondence with a borehole 33 similar to drilling 26 of this last figure.
  • holes or ducts such as 21, 22, 23, 26, 29, 32 and 33 can be made by drilling, drilling, pin demolding or sand core in the mold.
