Definitions

  • the present invention relates to a variable distribution device for modifying at will the distribution of an internal combustion engine with controlled ignition.
  • the distribution is ensured by a camshaft carrying an intake cam and an exhaust cam controlling respectively, either directly or via a rocker arm, the intake and exhaust valves.
  • a camshaft carrying an intake cam and an exhaust cam controlling respectively, either directly or via a rocker arm, the intake and exhaust valves.
  • the invention aims more precisely to provide a simple device making it possible no longer to produce a continuously variable distribution, but a two-stage device therefore with two cams.
  • variable distribution device is characterized in that it comprises at least two rocker arms each controlled by a cam of configuration suitable for a determined load of the motor, and having an element common connectable slidingly mounted on the rocker arm ramp and arranged to control the intake valve of a cylinder of the engine, this connectable element being associated with control means making it possible to connect and disconnect it at will from one or the other rocker.
  • These intake cams C 1 , C 2 are intended to actuate respectively two rocker arms 2 ef 3 articulated on a shaft 13 and immobilized in translation by pins 14 moving in corresponding grooves provided on the internal face of the rocker arms.
  • the rocker arms 2, 3 are provided with latching means, for example a notched structure (15), intended to be fitted into a corresponding structure provided on each of the side faces of the element. connectable 1 common to the two rocker arms 2, 3.
  • This connectable element 1 is capable of being actuated in translation by means of a control device 7, 8 enabling it to be engaged either on the rocker arm 2 or on the rocker arm 3 and to respectively control the valve 10 or by the cam C 1 either by cam C 2 .
  • the disconnectable element 1 slidably mounted on the shaft 13 is shaped so as to present on the one hand a zone 1a cooperating with the fork 8 secured to the shaft 7, and on the other hand a zone 1b carrying a rocker screw which can slide a sufficient distance owing to the fact that the upper face of the cup 10a is at the level of the shank 10 of the valve
  • Springs 5, 6 are respectively provided for holding the rocker arms 2, 3 in abutment on their respective cams C 1 , C 2 .
  • the means for controlling the element 1 in translation on the shaft 13 can be actuated in any suitable manner, for example mechanically, hydraulically (using the engine oil pressure) or electrically.
  • Such a device provided that the cams are judiciously sized, that is to say one optimized for partial loads, the other for full loads, ensures a good compromise in operation over the entire speed range and engine load.
