Definitions

  • the present invention refers to an air clear for an internal combustion motor of the type with a cleaner element made of paper.
  • Air cleaner are already known which consist of an external case provided with an entrance opening for the air and of a torque conduit exiting towards the intake manifold in which a filtering cartridge, consisting of paper pleated in rectangular parallelepiped shape and with a holding and fixing edge, generally made of plastic, is placed perpendicularly to the air flow.
  • This embodiment is an alternative to the one of cylindrical shape, more often used, and in some cases allows to make better use of the spaces inside the engine compartment of the motor vehicle.
  • One of the methods to increase the front surface of the paper air cleaner is that of placing the air cleaner in such a way that it is bent in relationship to the longitudinal axis of the feeding conduit and therefore to the direction of the flow lines of the air.
  • the air cleaner when the air cleaner is placed in this way, since the shape of a standard filtering element is that of a rectangular parallelepiped, the case of the air cleaner will necessarily present an angled profile which can both affect the air flow downstream the filtering element, thus reducing the overall efficiency of the air cleaner, and occupy more space inside the engine compartment.
  • reference number 1 indicates an air cleaner for an internal combustion motor, consisting of a case 2, provided with an entrance conduit 3 and an exit conduit 4.
  • the case consists of two parts 5 and 6 which are united by means of a joint 8 and are assembled by elastic means, for instance snap springs (not shown).
  • elastic means for instance snap springs (not shown).
  • the holding edge 9 is fixed inside the case of the filter, so that the plane that it defines is bent in relationship with the longitudinal axis of the exit conduit for the air, so that it opposes a larger surface to said air.
  • the body made of pleated paper 11 of the cartridge 10 is parallelepiped in shape and its longer sides are parallel to the plane which the holding edge 9 defines.
  • the shorter sides are instead parallel to the axis of said exit conduit 4 for the air.
