Abstract

Manocontact pour circuit hydraulique sous pression. La membrane prévue entre le plongeur qui commande le contact électrique est réalisée par un empilage de trois disques, l'un au contact du liquide réalisé en caoutchouc nitrile vulcanisé au soufre, un autre en polyuréthane au contact du plongeur et le troisième en polytétrafluoréthyléne interposé entre deux premiers. Application aux circuits de suspension et/ou freinage des véhicules automobiles.
