Summary: | A contactless seal intended for being fitted in a wall and a shaft passing through an opening of the wall, the seal comprising a rotary member intended for being supported by the shaft and a stationary member intended for being supported by the opening, the stationary member being inserted around the rotary member while being rotatably movable relative to same, the rotary member having an outer surface provided with at least one circumferential rib and the stationary member having an inner surface provided with at least one groove, or vice-versa. Each rib is partially inserted into a corresponding groove in order to form a labyrinthine leak path. The rotary member and the stationary member are each made up of a single part, and the rotary member and/or the stationary member are obtained by additive manufacturing. |
