Definitions

  • FIGS 3a-3c show sectional views of various designs wherein the guide rings and the stationary ring engage with each other at different inclination angles;
  • FIG. 6 is a sectional view of the cylinder and the stationary ring shown in FIG. 5 to show thermal deformations thereof and
  • FIG. 7 is a cross-sectional view of another modification of the cylinder and the stationary ring.
  • deformation of the peripheral portion of the cylinder caused by thermal expansion is prevented by designing the cylinder to have a cylindrical configuration and by obviating the adverse effect caused by the thermal displacement of the peripheral portion of the cylinder by causing the extension of the contact surfaces between the guide rings and the stationary ring to interest each other at or near the neutral point of the cylinder.
