Abstract

Procédé de fabrication d'un corps de pompe ou moteur hydraulique à barillet, constitué d'une couronne cylindrique percée de cylindres d'axes parallèles débouchant sur l'une des faces et raccordés à l'autre face par un conduit de diamètre plus faible, l'alésage et la face du côté des conduits étant revêtus d'alliage antifriction. On réalise une ébauche dans laquelle les cylindres traversent complètement la couronne, on ferme par un fond et on coule l'alliage dans le moule ainsi formé. Enfin, on usine les alésages, les conduits et la face revêtue. On peut fabriquer de cette manière deux barillets à la fois.A method of manufacturing a pump body or a hydraulic cylinder motor, consisting of a cylindrical crown pierced with cylinders of parallel axes opening out on one side and connected to the other side by a duct of smaller diameter, the bore and the side face of the ducts being coated with an anti-friction alloy. A blank is produced in which the cylinders pass completely through the crown, it is closed with a bottom and the alloy is poured into the mold thus formed. Finally, the bores, the conduits and the coated face are machined. Two barrels can be made in this way at the same time.
