Abstract

Machine à engrenage intérieur (pompe ou moteur) comportant un caner, un pignon engrenant avec une roue à denture intérieure et une piece de remplissage en contact avec le pignon et avec la roue à denture intérieure pour délimiter une chambre de refoulement. La pièce de remplissage monobloc 20 comporte une chambre intérieure qui s'étend à travers la pièce de remplissage sensiblement sur toute la longueur de cette pièce mesuree parallèlement aux axes de rotation des roues dentées, 15, 16, qui communique avec la chambre de refoulement 19 et dont les dimensions de la section sont telles que sous l'effet de la pression hydraulique la pièce de remplissage se dilate élastiquement. Application : moteurs ou pompe à engrenage intérieur.Internal gear machine (pump or motor) comprising a caner, a pinion meshing with an internal toothed wheel and a filling piece in contact with the pinion and with the internal toothed wheel to define a discharge chamber. The one-piece filling part 20 has an interior chamber which extends through the filling part substantially over the entire length of this part measured parallel to the axes of rotation of the toothed wheels, 15, 16, which communicates with the discharge chamber 19 and of which the dimensions of the section are such that under the effect of the hydraulic pressure the filling part expands elastically. Application: motors or internal gear pump.
