Abstract
CIRCUIT DE RETOUR D'HUILE POUR LE COMPRESSEUR D'UNE INSTALLATION DE REFRIGERATION MECANIQUE. LE CIRCUIT COMPORTE UN CONDUIT 48, 50 QUI RELIE UNE PREMIERE CHAMBRE 46 DU COMPRESSEUR 12 QUI EST A LA PRESSION DE REFOULEMENT DU COMPRESSEUR A UNE SECONDE CHAMBRE 44 DU COMPRESSEUR QUI EST A LA PRESSION D'ASPIRATION DU COMPRESSEUR POUR PERMETTRE A L'HUILE ACCUMULEE DANS LA PREMIERE CHAMBRE DE S'ECOULER DANS LA SECONDE CHAMBRE. UNE SOUPAPE 28 NORMALEMENT FERMEE EST MONTEE DANS LE CONDUIT 48, 50 POUR COMMANDER L'ECOULEMENT DE L'HUILE DANS CE CONDUIT. UN DETECTEUR DETECTE LA GRANDEUR DE LA PRESSION REGNANT DANS LA SECONDE CHAMBRE 44 ET OUVRE LA SOUPAPE LORSQUE CETTE PRESSION TOMBE AU-DESSOUS D'UN NIVEAU PREDETERMINE. APPLICATION, NOTAMMENT, AUX INSTALLATIONS DE CLIMATISATION DE VEHICULES, TELS QUE DES AUTOCARS.OIL RETURN CIRCUIT FOR THE COMPRESSOR OF A MECHANICAL REFRIGERATION SYSTEM. THE CIRCUIT INCLUDES A DUCT 48, 50 WHICH CONNECTS A FIRST CHAMBER 46 OF THE COMPRESSOR 12 WHICH IS AT THE COMPRESSOR DISCHARGE PRESSURE TO A SECOND CHAMBER 44 OF THE COMPRESSOR WHICH IS AT THE COMPRESSOR SUCTION PRESSURE TO ALLOW ACCUMULATED OIL IN THE FIRST BEDROOM TO FLOW INTO THE SECOND BEDROOM. A NORMALLY CLOSED VALVE 28 IS MOUNTED IN THE DUCT 48, 50 TO CONTROL THE FLOW OF OIL THROUGH THIS DUCT. A SENSOR DETECTS THE SIZE OF PRESSURE IN SECOND CHAMBER 44 AND OPENS THE VALVE WHEN THIS PRESSURE FALLS BELOW A PREDETERMINED LEVEL. APPLICATION, IN PARTICULAR, TO AIR-CONDITIONING SYSTEMS FOR VEHICLES, SUCH AS COACHES.
