Abstract
This invention relates to a piston for reciprocating and simultaneously rotating through a predetermined length of movement within a piston bore having a piston bore surface, and a method for reducing wear on a piston bore surface operatively associated with a piston which is subject to cocking forces. The piston includes a means on its extreme portion for providing continuous, tangential cooperation with the piston bore surface within the predetermined length of piston movement to reduce wear on the piston bore surface.
