ABSTRACT:
The present invention concerns a piston for high pressure hydraulic machines. Said piston comprises a cylindrical body having at the periphery thereof a resiliently deformable cylindrical flange which, in use, forms a tight seal with the cylinder, the flange being integral with the piston body and forming, by means of its inner surface, a recess in the end face of the piston which is subjected to high pressure.
