Abstract

Aeration valve for hydraulic circuits made up of a frame (1-2) fitted with inlet and outlet openings (25, 26) inside which is housed a float (4) fitted with an upper closure capsule (5) further fitted with a joint (18) capable of resting against a seating surface (27) of the housing whenever the float is displaced towards its upper limiting position. Inside the housing is arranged a fixed sleeve (3) that incorporates a lower seating surface (10), upon which rests the float at its lower limiting position, and which forms, together with the housing, a ring shaped passage.
