Abstract

Dans un dispositif de compression (A), de l'air est comprimé par un compresseur (1); l'air comprimé est contenu dans un réservoir (4) ; la pression de l'air dans le réservoir (4) est détectée par un détecteur (5), et lorsque ledit détecteur détecte que la pression de l'air dans le réservoir (4) a atteint un niveau prédéterminé, le compresseur (1) est arrêté. Lorsqu'un dispositif de compression (A) est connecté à un autre dispositif de compression (A), un premier dispositif de liaison (15) relie les réservoirs (4) de ces dispositifs de compression pour permettre un échange d'air à une pression principale, et un second dispositif de liaison (16) amène les deux détecteurs (5) à se reconnaître à la suite d'une détection par le détecteur (5) du premier dispositif de compression (A) et à la suite de la détection par le détecteur (5) de l'autre dispositif de connexion (A) connecté au détecteur (5) du premier dispositif de compression. Lorsque l'un des détecteurs (5) détecte que la pression de l'air dans le réservoir (4) atteint le niveau prédéterminé, tous les compresseurs (1) sont arrêtés.
