ABSTRACT An internal-combustion engine valve gasket (1) comprising an annular sealing element (12), which is elastically deformable and is designed to be set externally on the valve (2) to co- operate both with a guide element (7) and with a stem (8) of the valve itself, and an annular supporting member (13), which is set coaxially on part of the sealing element (12) so that the latter is radially pressed between the supporting member (13) and the valve (2); the supporting member (13) comprises a first portion (25) for interaction with the sealing element (12) and a second portion (26) for positioning in use the gasket (1) on the engine (3); the first and second portions of the supporting member (13) form part of a first component (25) and a second component (26), that are distinct from one another and are mounted coaxially by snap-action coupling means (27).

Abstract

There is described a seal assembly for sealing the gap between a rotary member and a fixed member, so as to prevent passage of a fluid from a first to a second environment located on opposite sides of the gap; the seal assembly has a first ring integral with the rotary member, a second ring integral with the fixed member, and an elastically deformable sealing member integral with the second ring and in turn having at least one lip cooperating in fluidtight manner with a mating portion of the first ring; and, on the side cooperating with the mating portion, the sealing member has a spiral groove which, in use, produces a fluid-dynamic pumping effect to pump the fluid away from the sealing area and towards the first environment.
