Abstract

L'INVENTION CONCERNE L'INDUSTRIE DES POMPES. POMPE VOLUMETRIQUE, NOTAMMENT POMPE A ENGRENAGES, POUR TRANSPORTER UN FLUIDE EN DEUX ETAPES, LA PREMIERE ETAPE DE TRANSPORT S'EFFECTUANT D'UN RESERVOIR DANS UNE CHAMBRE INTERMEDIAIRE ET LA SECONDE ETAPE DE TRANSPORT S'EFFECTUANT DE LA CHAMBRE INTERMEDIAIREA UN CIRCUIT D'UTILISATION, PAR L'INTERMEDIAIRE D'UNE CONDUITE SOUS PRESSION, LA CHAMBRE INTERMEDIAIRE ET LA CONDUITE SOUS PRESSION ETANT RELIEES A UN DES DEUX COTES DE REFOULEMENT D'UN DISPOSITIF DE REGULATION DE PRESSION, ET LA CONDUITE SOUS PRESSION ARRIVANT AU DISPOSITIF DE REGULATION DE PRESSION PAR L'INTERMEDIAIRE DE L'ORGANE DE REGLAGE; AU DISPOSITIF DE REGULATION DE PRESSION 10 EST ASSOCIE UN DISPOSITIF DE LIMITATION DE PRESSION 31 QUI MAINTIENT LA PRESSION CONSTANTE D'UN DES COTES DE REFOULEMENT 14 DU DISPOSITIF DE REGULATION DE PRESSION 10. APPLICATION NOTAMMENT AUX POMPES D'ALIMENTATION DE BRULEURS A MAZOUT.THE INVENTION CONCERNS THE PUMP INDUSTRY. VOLUMETRIC PUMP, IN PARTICULAR GEAR PUMP, TO TRANSPORT A FLUID IN TWO STAGES, THE FIRST TRANSPORT STAGE IS CARRIED OUT FROM A TANK IN AN INTERMEDIATE CHAMBER AND THE SECOND TRANSPORT STAGE FROM THE INTERMEDIATE CHAMBER USING A CIRCUIT , THROUGH A PRESSURE PIPING, THE INTERMEDIATE CHAMBER AND THE PRESSURE PIPE BEING CONNECTED TO ONE OF THE TWO DISCHARGE SIDES OF A PRESSURE REGULATING DEVICE, AND THE PRESSURE PIPING COMING TO THE PRESSURE REGULATING DEVICE THROUGH THE ADJUSTMENT BODY; THE PRESSURE REGULATION DEVICE 10 IS ASSOCIATED WITH A PRESSURE LIMITATION DEVICE 31 WHICH MAINTAINS THE PRESSURE CONSTANT OF ONE OF THE DISCHARGE SIDES 14 OF THE PRESSURE REGULATORY DEVICE 10. APPLICATION IN PARTICULAR TO PUMPS FOR SUPPLYING OIL BURNERS.
