Abstract
A filtering device includes a tubular outer body with an intermediate chamber containing a pair of cup-shaped valve elements mounted floating and slidable coaxially with opposing cavities in which an axially compressed spring is housed. The first cup-shaped valve element is arranged coaxially outside the second cup-shaped valve element and has a base with a central through opening and a tubular portion with a series of ribs. The second cup-shaped valve element has a perforated base abutting against a perforated plug fixed to one side of the cavity passing towards the master cylinder. The perforated plug forms a through seat that slidably houses an appendage of the second cup-shaped valve element. Passages are formed around the plug that establish fluid communication between the intermediate chamber and a passage to the master cylinder.
