Abstract

MACHINE A ENGRENAGE COMPORTANT UN CARTER PERIPHERIQUE, DEUX FLASQUES LATERAUX, DES PIGNONS PORTES SUR AU MOINS UN DE LEURS COTES PAR UN PALIER FLOTTANT ET DES MOYENS POUR DETERMINER CONTRE LA FACE EXTERIEURE DU PALIER FLOTTANT UNE CHAMBRE EXCENTREE PAR RAPPORT AUX AXES DES PIGNONS ET DONT LA MAJEURE PARTIE EST SITUEE DU COTE DE LA HAUTE PRESSION; CETTE CHAMBRE RECOIT UN FLUIDE DONT LA PRESSION CROIT AVEC LA HAUTE PRESSION. UNE SECONDE CHAMBRE EXCENTREE 16 EST FORMEE CONTRE LA FACE EXTERIEURE DU PALIER, LA MAJEURE PARTIE DE CETTE SECONDE CHAMBRE 16 ETANT SITUEE DU COTE DE LA BASSE PRESSION E; DES MOYENS 19A, 19B ADMETTENT DANS CETTE SECONDE CHAMBRE DU FLUIDE DONT LA PRESSION VARIE DANS LE MEME SENS QUE LA BASSE PRESSION DE LA MACHINE. UN PISTON COMPENSATEUR 20 EST AVANTAGEUSEMENT PREVU. APPLICATION AUX MOTEURS ET POMPES HYDRAULIQUES A ENGRENAGE.
