Abstract

La présente invention porte principalement sur une valve d'entrée d'air (12) pour amplificateur pneumatique de freinage, ladite valve d'entrée d'air (12) comportant: - un premier filtre (21) peu perméable présentant une grande qualité de filtrage et un faible débit de passage d’air, - une coupelle (23) de limitation de déformation maximale dudit premier filtre (21), - un deuxième filtre (22) très perméable présentant un débit élevé de passage d’air et une faible qualité de filtrage, - ladite valve d'entrée d'air (12) étant configurée de telle façon que lorsqu'un débit d’air traversant la valve d'entrée d'air (12) augmente, le premier filtre (21) est apte à se déformer jusqu’à venir tout ou partie en appui sur la coupelle (23), de manière à libérer une section de passage d'air en périphérie externe dudit premier filtre (21). Figure 6aThe present invention relates mainly to an air inlet valve (12) for a pneumatic brake amplifier, said air inlet valve (12) comprising: - a first low permeability filter (21) having a high quality of filtering and a low air flow rate, - a cup (23) for limiting the maximum deformation of said first filter (21), - a second highly permeable filter (22) having a high air flow rate and a low filtering quality, - said air inlet valve (12) being configured such that when an air flow through the air inlet valve (12) increases, the first filter (21) is capable of deforming until it comes fully or partially resting on the cup (23), so as to free an air passage section at the outer periphery of said first filter (21).
