Abstract

L'invention concerne un nouveau régulateur de pression (1) de compresseur d'air jamais décrit jusqu'alors. Ledit régulateur (1) comporte les instruments et composants de base c,-à-d.: une soupape régulatrice de pression (3.4), une soupape de sûreté (3.9), une soupape de décharge (3.10), un bouton d'arrêt d'urgence (2.6), et un commutateur de sélection (3.6), le tout intégré dans un carter robuste et pratique (2,3) présentant une entrée (3.8) et une sortie (3.11). Selon l'invention, le régulateur de pression (1) présente un modèle principal et une variante de construction, ledit modèle principal étant essentiellement numérique (2.3, 2.4, 2.5) et la variante de construction essentiellement analogique (4.1). Selon l'invention, les principaux avantages de l'utilisation dudit régulateur de pression(1) découlent des caractéristiques suivantes: facilité d'installation, interface simple et agréable et longue durée de vie des composants et instruments, lesquels sont protégés par un carter robuste.
