ABSTRACT:
A wide channel seal for impeding the leakage of a gaseous medium between the rotor and stator of a rotary machine is disclosed. Various construction details including the use of a honeycomb facing material on the stator side of the channel and the use of a grooved cylindrical surface on the rotor side of the channel are discussed. A comparison in sealing effectiveness between a conventional wide channel seal and the wide channel seal of the present invention is made.
