Abstract

REGULATEUR DE PRESSION POUR EQUIPEMENT A ACCUMULATEUR D'AIR COMPRIME, QU'UN COMPRESSEUR REMPLIT PAR L'INTERMEDIAIRE D'UN CLAPET DE NON-RETOUR, AVEC UN PREMIER PISTON PILOTE DONT LE FOND, CONSTITUANT LA SURFACE EFFECTIVE, DELIMITE UNE PREMIERE CHAMBRE DE PILOTAGE, UNE SECONDE CHAMBRE DE PILOTAGE DELIMITEE PAR UN SECOND PISTON PILOTE RELIE A UNE SOUPAPE D'ECHAPPEMENT, ET UNE SOUPAPE DISPOSEE ENTRE LA PREMIERE ET LA SECONDE CHAMBRE DE PILOTAGE POUR AERER ET PURGER LA SECONDE CHAMBRE. DES MOYENS 10, 11, 23, 21 DISPOSES ENTRE LA PREMIERE CHAMBRE DE PILOTAGE 5 ET LA SECONDE 20 ASSURENT L'ETANCHEITE A LA PRESSION ENTRE LA BASE DE L'OBTURATEUR 22 DE SOUPAPE ET LA SECONDE CHAMBRE 20, AFIN DE MAINTENIR LA SURFACE EFFECTIVE DU PREMIER PISTON PILOTE 2 CONSTANTE, INDEPENDAMMENT DE LA POSITION DE CE DERNIER. DES MOYENS SUPPLEMENTAIRES 30 INTEGRENT LA BASE 11 DE L'OBTURATEUR 22 A LA SURFACE EFFECTIVE DU PREMIER PISTON PILOTE 2.PRESSURE REGULATOR FOR EQUIPMENT WITH COMPRESSED AIR ACCUMULATOR, WHICH A COMPRESSOR FILLS THROUGH A NON-RETURN VALVE, WITH A FIRST PILOT PISTON WHOSE BOTTOM, CONSTITUTING THE EFFECTIVE SURFACE, DELIMITS A FIRST PILOT CHAMBER , A SECOND PILOT CHAMBER DELIMITED BY A SECOND PILOT PISTON CONNECTED TO AN EXHAUST VALVE, AND A VALVE LOCATED BETWEEN THE FIRST AND SECOND PILOT CHAMBER TO AERATE AND DRAIN THE SECOND CHAMBER. MEANS 10, 11, 23, 21 PROVIDED BETWEEN THE FIRST PILOT CHAMBER 5 AND THE SECOND 20 ENSURE THE PRESSURE LEAKAGE BETWEEN THE BASE OF THE VALVE SHUTTER 22 AND THE SECOND CHAMBER 20, IN ORDER TO MAINTAIN THE EFFECTIVE SURFACE OF THE FIRST PILOT 2 CONSTANT PISTON, INDEPENDENT OF THE POSITION OF THE LATTER. ADDITIONAL MEANS 30 INTEGRATE THE BASE 11 OF THE SHUTTER 22 IN THE EFFECTIVE SURFACE OF THE FIRST PILOT PISTON 2.
