Abstract
A method for manufacturing radial pistons for a hydraulic motor by machining cylindrical transverse holes at regular intervals in a bar, and, in order to form two adjacent pistons, cutting up the bar on a transverse cutting-up plane passing through one of said holes so that a first portion of said hole forms a cradle-shaped recess in the base of the first one of the two adjacent pistons and so that another portion of said hole forms a cradle-shaped recess in the top of the second one of the two adjacent pistons.
