Abstract

L'INVENTION CONCERNE UNE POMPE VOLUMETRIQUE, EN PARTICULIER POUR UN BRULEUR A MAZOUT DE FAIBLE PUISSANCE, AYANT PAR EXEMPLE UN DEBIT INFERIEUR A 2 LITRESHEURE. UN PREMIER ETAGE 2 DE LA POMPE ASPIRE DANS UN RESERVOIR, ET REFOULE DANS UNE CHAMBRE INTERMEDIAIRE 8 OU ASPIRE UN SECOND ETAGE 4 QUI REFOULE DANS UNE CANALISATION DE PRESSION 11. A CELLE-CI EST ASSOCIE UN REGULATEUR 10 PAR EXEMPLE A MEMBRANE 13, QUI COMMUNIQUE AVEC AU MOINS UNE PARTIE DU CIRCUIT EN AVAL DE LA CHAMBRE INTERMEDIAIRE 8, TELLE QUE LA CANALISATION DE REFOULEMENT 11, OU UNE CANALISATION DE RETOUR 9. LES DEPLACEMENTS DE LA MEMBRANE 13 FERMENT PLUS OU MOINS DES ZONES D'ETRANGLEMENT 21, 22 CONTROLANT LE DEBIT VERS L'UTILISATION OU VERS LE RETOUR AU RESERVOIR. APPLICATION AUX POMPES VOLUMETRIQUES, POUR ASSURER DE MANIERE ECONOMIQUE UN DEBIT CONSTANT, EN COMPENSANT LES VARIATIONS DE VISCOSITE DU FLUIDE REFOULE, EN PARTICULIER SUR DES POMPES DE BRULEURS A MAZOUT DE FAIBLE PUISSANCE.
