Abstract: A sealing lid for sealing a compartment of a supercapacitor housing electrodes and electrolytic material is described, the supercapacitor comprises: a casing internally defining the compartment and having a longitudinal axis, a side wall extending around the longitudinal axis, an axial bottom wall and an axial opening for accessing to the compartment arranged on an axially opposite side of the side wall with respect to the end wall; and at least one terminal electrically connected to one of the electrodes and protruding outside the compartment through the axial opening; the lid is adapted to close the axial opening and comprises an elastomeric element having: an internal through-hole adapted to receive the terminal and delimited by an internal wall adapted to cooperate in fluid-tight contact with the terminal; and a peripheral wall adapted to cooperate in fluid-tight contact with the side wall.

Abstract: A gasket is described configured to be mounted on a valve of an internal combustion engine, having a central axis and comprising: an annular elastically deformable sealing element, having a radially internal surface having a first portion, adapted to cooperate with contact with a stem of the valve, and a second portion, configured to cooperate with contact with a guide element in a sliding manner of the aforementioned stem; and an annular support member, arranged coaxially on at least part of the sealing element so that the latter is pressed radially between the support member and the valve; the second portion has a circumferential surface section and a plurality of discrete bumps, projecting cantilevered from the circumferential surface section so as to cooperate with contact in use with the guide element, angularly spaced from each other around the axis and forming a discontinuous undulation of the radially internal surface.

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.
