Definitions

  • Figs. 10A and 10B illustrate a piston 22 according to a eighth embodiment.
  • the skirt 42 is mechanically fixed to the cylinder 41 by a fastener ring 60. That is, the boss 43a of the lid 43 has no annular groove 43b.
  • a rim 58 is integrally formed with the lid 43. The outer diameter of the rim 58 is equal to the outer diameter of the cylinder 41.
  • a semi-cylinder 70a is formed at the distal end of the rim 58.
  • a semi-cylinder 70b is also formed at the open end of the cylinder 41.
