Abstract: It is described a gasket for a valve of an internal combustion engine having a central axis and comprising: an elastically deformable sealing element having an annular shape with respect to the aforesaid axis and adapted to be externally arranged on the valve, and a support element, also having an annular shape with respect to the aforesaid axis, coaxially arranged on at least part of the sealing element so that this latter is radially pressed between the support element and the valve; the support element having, along its side wall, at least one through window to allow the evacuation of the heat generated in use during the operation of the valve.

Abstract: It is described a gasket for a valve of an internal combustion engine, having an axis and comprising an annular sealing element to be externally arranged on the valve and an annular support element, coaxially arranged on the sealing element to press it radially on the valve; the support element comprising a first annular component, internally cooperating with the sealing element, a second annular component, coaxially surrounding the first component, and snap coupling means between these components; the second component comprising an annular main body and an outer annular end flange; the main body further having an annular edge projecting towards the axis and defining an axial abutment for the first component; the snap coupling means comprising two or more hooking projections angularly equidistant about the axis, cantileverly extending from the annular edge towards the flange and cooperating in contact with the first component to abuttingly keep it against the annular edge.
