Gasket for a valve of an internal combustion engine

Abstract

A gasket ( 18 ) for a valve ( 12 ) of an internal combustion engine ( 1 ) includes a supporting element ( 26 ) having a tubular conformation according to an axis (B), and an elastically deformable element ( 25 ) adapted to be arranged between the valve ( 12 ) and the supporting element ( 26 ). The supporting element ( 26 ) includes a first portion ( 42 ) extending transversally to the axis (B) and adapted to receive an action with component parallel to the axis (B) itself to facilitate the assembly of the gasket ( 18 ) on the valve ( 12 ), and a second portion ( 41 ) elongated towards the axis (B) from the first portion ( 42 ) and in turn including at least one segment ( 45 ) having an increasing radial dimension towards the first portion ( 42 ) itself ( 46 ) so as to reduce the volume of the elastically deformable element ( 25 ).

1 . A gasket ( 18 ) for a valve ( 12 ) of an internal combustion engine ( 1 ) comprising: 
 a supporting element ( 26 ) having tubular conformation according to an axis (B); and    an elastically deformable element ( 25 ) adapted to be placed between said valve ( 12 ) and said supporting element ( 26 );    characterized in that said supporting element ( 26 ) comprises a first portion ( 42 ) extending transversally to said axis (B) and adapted to receive an action with a component parallel to the axis (B) itself to facilitate the assembly of said gasket ( 18 ) on said valve ( 12 ), and    a second portion ( 41 ) elongated according to said axis (B) starting from said first portion ( 42 ) and in turn comprising at least one segment ( 45 ) having an increasing radial dimension towards the first portion ( 42 ) itself ( 46 ) so as to reduce the volume of said elastically deformable element ( 25 ).    
   
   
       2 . A gasket according to  claim 1 , wherein said second portion ( 41 ) comprises a first axial end segment ( 43 ) and a second axial end segment ( 44 ) extending parallel to said axis (B), and mutually joined by said increasing radial dimension segment ( 45 ).  
   
   
       3 . A gasket according to  claim 1 , wherein said supporting element ( 26 ) presents an axial end ( 46 ) opposite to said first portion ( 42 ) and bent towards said axis (B) to axially withhold said elastically deformable element ( 25 ).  
   
   
       4 . A gasket according to  claim 1 , wherein said first portion ( 42 ) comprises a first fraction ( 50 ) fastened to said elastically deformable element ( 25 ), and a second fraction ( 51 ), radially more external with respect to said first fraction ( 50 ), at least in part free in the direction of said axis (B) to receive said action with the parallel component to said axis (B).
