A method for producing a plunger barrel for hydraulic axial piston machines

摘要

P method of manufacture of a pump body or hydraulic motor mechanism, composed of a cylindrical ring pierced with rolls having parallel axes and emerging on one side and connected to the other face by a conduit of smaller diameter, the bore and the face of the side of the conduits being coated with antifriction alloy. / p & & p & it carries out a blank in which the cylinders completely traverse the ring, is closed by a bottom and the alloy is cast into the mold thus formed. Finally, it is machined, the bores, the ducts and the coated face. It can be manufactured in this way, two drums. / p
