ABSTRACT:
An improved method of manufacturing a piston is provided. The piston includes a substantially cylindrical member having a first end and a second end. The cylindrical member includes an open cavity extending axially from the second end to adjacent the first end such that the second end has an inner annular surface defined by an inner diameter. The piston further includes a disk having a radially outer surface defined by an outer diameter fixedly secured to the second end of the cylindrical member. The outer diameter of the disk is substantially equal to the inner diameter of the inner annular surface of the second end of the cylindrical member. A circumferentially extending recessed area for receiving particles produced while fixedly securing the disk to the second end of the cylindrical member is provided on either the radially outer surface of the disk or the inner annular surface of the second end of the cylindrical member.
