Abstract

Improvements in pistons for hydrostatic machines, characterized in that a freely rotating cam follower ball is arranged on each piston to follow a cam surface on the hydrostatic machine by alternating movement of the ball in the bore of a machine cylinder; a piston body to alternately move, along with the ball, the cylinder bore, the piston body having at one end an extreme working face on which the working fluid of the hydrostatic machine acts, and at another end a crater shaped ball seat, exposing the piston body a part of the ball protruding from the piston body to contact the cam surfaces, and a low friction synthetic plastic material insert having an internal support or friction surface for the ball, the insert of which is positioned between the ball and the seat in a position at the rear of the ball, to accept the support load of the ball when they contact the surface of the cam, and a separately formed retainer element that cooperates with the piston body to retain the ball in said piston body.
