Definitions

  • the present invention relates to some improvements in lubricating the seats of a camshaft and rocker arm shaft in an internal combustion engine, improvements intended for providing a better and effective greasing for all camshaft and rocker arm shaft seats.
  • the novelty of the invention is focused on a new arrangement of the lubrication pipes and also in the incorporation of at least two deep transverse bores located in the cylinder head; from which lubrication pipes are extended flowing precisely into the camshaft and rocker arm shaft seats.
  • the lubrication of the camshaft and rocker arm shaft seats in an internal combustion engine is carried out by driving pressurized oil through an internal circuit using a pump actuated by the engine itself, so that the flow rate of said oil reaches a single deep transverse bore that is part of this internal circuit while is located in the engine cylinder head, some pipes flowing into the camshaft and rocker arm shaft seats being extended from said single deep transverse bore.
  • the invention proposes some improvements in lubricating the seats of a camshaft and rocker arm shaft in an internal combustion engine.
  • Lubrication is in principle carried out through an internal pressurized oil circuit driven through a pump actuated by the internal combustion engine itself, said internal circuit comprising different pipes affecting the cylinder head and some of which flow into the camshaft and rocker arm shaft seats for lubricating and greasing thereof.
  • camshaft seats are located in the cylinder head, while the rocker arm shaft seats are located in an upper support connected to the cylinder head itself in solidarity and which also partially fixes said camshafts seats through the top the camshaft in correspondence with its seats.
  • the improvements consists in that the cylinder head comprises at least two deep transverse bores, from which upstream pipes are extended flowing into the camshaft and rocker arm shaft seats for lubricating and greasing thereof.
  • This described arrangement allows mounting anti-friction bushes in the respective seats regardless the location of the hole that usually carries for the oil to flow towards the rocker arm shaft and camshaft.
  • the improvements in lubricating the seats of a camshaft and rocker arm shaft in an internal combustion engine are focused on that the cylinder head 1 includes at least two deep transverse bores 2-3, from which upstream pipes 4-5 are extended flowing into some seats 6-7 of a camshaft 8 and a rocker arm shaft 9 for greasing and lubricating thereof.
  • the camshaft 8 seats 6 are located in the cylinder head 1
  • the rocker arm shaft 9 seats 7 are located in an upper support 10 fixed to the cylinder head 1, and which also supports at the top the camshaft 8 in correspondence to its seats 6.
  • Said upper support 10 rests on an upper surface 13 of the cylinder head 1.
  • the deep transverse bores 2-3 are part of an internal pressurized oil circuit driven through a pump that rotates by using the operating of the internal combustion engine itself.
  • a set of upstream pipes 4 is extended from one of the transverse bores 2 and such upstream pipes 4 flow into the camshaft 8 seats 6, whereas the other set of upstream pipes 5 is extended from another transverse paired-bore 3 and said upstream pipes 5 flow into the rocker arm shaft 9 seats 7.
  • the seats 6-7 may include arcuate slots 11-12 sandwiched in the upstream pipes 4-5 mouth.
