Abstract

Actionneur (4) électrique pour frein (2) de véhicule (1) automobile, comprenant : - un boitier (5), et - des moyens (8) de filtration portés par le boitier (5) et permettant une circulation de vapeur d’eau entre l’intérieur (9) et l’extérieur du boitier (5) et empêchant une circulation d’eau liquide entre l’intérieur (9) et l’extérieur du boitier (5). Une partie des moyens (8) de filtration est portée par une soupape (10) de sécurité montée mobile sur le boitier (5) entre une position fermée de repos dans laquelle elle est inactive et une position ouverte de sécurité dans laquelle elle est active. La soupape (10) de sécurité est configurée pour passer en position ouverte de sécurité lorsque la pression à l’intérieur (9) du boitier (5) atteint ou dépasse un seuil de pression prédéterminé. Figure pour l’abrégé : figure 3Electric actuator (4) for a brake (2) of an automobile vehicle (1), comprising: - a housing (5), and - filtration means (8) carried by the housing (5) and allowing circulation of steam water between the interior (9) and the exterior of the housing (5) and preventing a circulation of liquid water between the interior (9) and the exterior of the housing (5). Part of the filtration means (8) is carried by a safety valve (10) movably mounted on the housing (5) between a closed rest position in which it is inactive and an open safety position in which it is active. The safety valve (10) is configured to go into the safety open position when the pressure inside (9) of the housing (5) reaches or exceeds a predetermined pressure threshold.
