Definitions

  • the present invention relates to an internal combustion engine, the particular arrangement of the pressure pump of the type with tangential pinion gears, for the circulation of oil in the various organs, makes it possible to reduce the bulk and the weight. said motor, as well as its maintenance cost, for example during disassembly.
  • the pressure pump used to circulate the oil in the various greasing members is constituted by an autonomous mechanical assembly with closed casing, driven either directly by the crankshaft, or indirectly by the latter, by appropriate means. , such as gears or a toothed belt.
  • the engine according to the invention has, on the contrary, a pressure pump for the circulation of oil with a sump open on one side, closed by direct fixing on the cylinder head, the movable members of the pump being directly driven by the camshaft, to which they are secured by means of an axial stop.
  • the seal between the cylinder head and the pump body is ensured by O-rings and lip seals, and the axial play is adjusted by means of a flat washer, disposed between an annular shoulder of the body. pump and the corresponding internal face of the movable member of the pump driven by the camshaft.
  • FIG. 1 it appears that the pump 1, partially masked by the drive wheel 2 of the camshaft, is fixed by the screws 3 on the cylinder head 5 of the engine. Also shown in this figure are the inlet 6 and outlet 7 ducts for the pump oil as well as the inlet duct 8 for the oil in the distribution member 22 on the bearings of the shaft to cams.
  • the pulley 11 constitutes only a tensor for the belt coming from the pulley 9 fixed on the crankshaft.
  • Figure 2 which shows an enlarged view of the section along line II-II of Figure 1, shows the assembly of the camshaft 20, located in the cylinder head 5 with, on the one hand the oil distribution 22 on the bearings, and on the other hand the pump 1 and the flywheel 2.
  • the body of the pump 1 appears in dotted lines one of the fixing screws 24 of the pump body on the cylinder head.
  • the O-ring 25 seals between the pump body and the cylinder head, and the seal 26 between the pump body and the open end of the oil distribution member 22 on the shaft bearings with cams.
  • the washer 28 and the screw 29 constitute the stop for the camshaft, the latter being made integral with the drive wheel 2 in rotation by the key 30.
  • FIG. 3 which is an enlargement of a part of FIG. 2, makes it possible to better understand the embodiment of the invention at the level of the pump itself.
  • the reference 40 designates the drive pinion of the gear pump and the reference 41 designates the idler gear.
  • the part 43 is a collar ring, engaged on the camshaft 20, between the flywheel 2 and the pinion 40, the lip seal 45 bearing on said collar ring.
  • the pinion 40 is itself supported on the annular shoulder 50 of the camshaft.
  • the planar washer 47 is positioned between the internal face of the drive pinion 40 and a shoulder 49 of the pump block. In this shoulder also appears in dotted lines a breather 51 connecting the space where the seal 45 is located and the suction side of the pump.
  • Figure 4 shows the inlet ports 53 and outlet 54 of the oil; the holes 56 are intended for the guide pins and the holes 24 for the assembly screws 3; the grooves 58 and 59 are intended to receive the seals between the body of the pump 1 and, on the one hand the cylinder head 5, on the other hand the oil distribution member 22 on the bearings of the camshaft.
  • Reference 60 designates the safety valve assembly.
  • the return duct 62 of the safety valve also appears in section in FIGS. 2 and 3.
  • the seal between the pump body and the cylinder head is ensured by the O-ring 25, housed in the groove 58, and kept in pressure by means of the screws 3. It therefore appears, once the drive wheel 2 removed, that the simple unscrewing of the screws 3 allows both to remove and disassemble the pump for its maintenance.
  • the O-ring 26, housed in the groove 59 makes it possible to hermetically seal the orifice of the duct of the oil distribution member 22, said orifice resulting from the imperatives of machining.
