Abstract

An air filter, comprising a casing (1, 6) with an inlet port (4) and an outlet port (2) and internally provided with filter means, is provided, transversely to the passage of the filtered air downstream of the filter means, with a perforated diaphragm (17, 18) and a deformable valve element (19) which allows the air to pass only in the direction of the intake manifold.
