Definitions

  • the present invention refers to a device to separate oil vapours from the crankcase of an internal combustion engine (blow by) provided with manifolds for connection to the blow-by circuit of said vapours and of a manifold to let fresh oil in the crankcase sump.
  • the separator device for the blow-by oil vapours that come from the sump and from the crank chamber, is typically made as a separate part which is added to the engine when this one is being assembled.
  • One of the advantages of the present invention consists in that it presents two access manifolds to the separator from the crank chamber, said access manifolds being spaced and located on a plane parallel to the axis of the crankcase. This makes it possible to keep one manifold constantly free, even in the case the inclination of the engine is very high, so that no oil can be sucked into the crank chamber.
  • the reference number 2 indicates the crankcase of an internal combustion engine made by means of ground fusion.
  • the crankcase presents in-line cylinders and one crank chamber 5 on the side wall of the cylinders.
  • at least two passages 6 and 7 for the oil vapours are built by fusion in correspondence with the second and third bay of the crankcase. Said passages, which are positioned in order not to interfere with the connecting rods, and which lay, spaced, on a plane parallel to the longitudinal axis of the crankcase, make the crank chamber communicate with the external wall of the crankcase through the holes 9 and 10.
  • the holes 9 and 10 open inside a body forming the lower section, or base, 11, of a compartment for the separation 12 of oil vapours, said compartment being basically shaped as an equilateral triangle, in correspondence with the ends of one of its sides which is basically parallel to the plane defined by the upper face of the crankcase.
  • This separator built by fusion together with the crankcase, presents inside walls forming a labyrinth and one vertex pointing towards the lower part of the crankcase.
  • the upper section or cover 13 of the separator compartment which is made separately, again presents in its internal part the labyrinth pattern of the crankcase 11, and presents two manifolds 15 and 16, being the first one 15 adapted to carry vapours to the blow-by system and the second one 16 used as an inlet for fresh oil.
  • a passage 18, is made centrally, in correspondence with the vertex pointing downwards, in the separator 12 and in the wall of the crankcase, and a manifold 19 built by fusion and connected to it, allow to introduce oil in the engine sump.
  • the base and the cover of the separator are jointed by conventional means, i.e. screws, and a seal (not shown) can be put between them if necessary.
  • the two manifolds spaced and parallel to the axis of the crankcase, allow the suction of blow-by vapours to be always free, independently from the working position of the engine.
