Abstract

Une telle machine est utilisable comme pompe ou comme moteur et comprend des pignons en prise par des dentures extérieures. Selon l'invention, au moins le pignon sur l'arbre d'entraînement d'une telle machine est divisé perpendiculairement à son axe en deux pignons, 17 et 18, dont les dents et les entredents sont essentiellement alignés et dont l'un, 18, est disposé libre en rotation et axialement coulissant sur l'arbre d'entraînement 15, alors que l'autre pignon, 17, est disposé fixe sur cet arbre. Les pignons 17 et 18 sont en prise avec un seul pignon 21 sur l'arbre mené 22, ou avec deux pignons sur l'arbre mené. La pulsation du débit ou du courant de fluide absorbé d'une telle machine est ainsi fortement réduite.Such a machine can be used as a pump or as a motor and comprises pinions engaged by external teeth. According to the invention, at least the pinion on the drive shaft of such a machine is divided perpendicularly to its axis into two pinions, 17 and 18, of which the teeth and the entredents are essentially aligned and one of which, 18, is disposed freely in rotation and axially sliding on the drive shaft 15, while the other pinion, 17, is disposed fixed on this shaft. The pinions 17 and 18 mesh with a single pinion 21 on the driven shaft 22, or with two pinions on the driven shaft. The pulsation of the flow or stream of fluid absorbed from such a machine is thus greatly reduced.
