Abstract

Dispositif de commande mécanique assistée par fluide sous pression distribué à un vérin à deux chambres relié au mécanisme à actionner, en particulier pour commande de direction de véhicule, comportant un organe de commande manoeuvrable à volonté et un organe d'actionnement dudit mécanisme entre lesquels est interposé un distributeur de fluide sous pression comprenant un corps et deux tiroirs mobiles dans celui-ci, contrôlant la distribution de fluide sous pression respectivement aux deux chambres du vérin, et dans lequel les tiroirs sont soumis à une pression de rappel déterminant un seuil d'effort à partir duquel l'assistance intervient, ce seuil résultant ici d'une pression prédéterminée réglable et/ou automatiquement variable en fonction d'un paramètre du véhicule.
