Abstract

PURPOSE: To prevent O ring from flowing out and thus to seal internal fluid thoroughly by enclosing the O ring and an backup ring in a groove provided on the outer periphery of a thin annular O ring retainer.
CONSTITUTION: A thin O ring retainer 6 is placed in a cut 13 provided on the edge internal pressure side of an end cover 2. There is provided an O ring groove 14 on the O ring retainer 6 at its outer periphery, and an O ring 4 and a backup ring 5 are enclosed therein. The retainer 6 is fitted loosely on the end cover 2 with a ringed stopper 7 and a bolt 8. Margins 10, 11 are provided on the retainer 6 so as to have clearances 15, 16 between the retainer 6 and the bottom of the cut 13 and the stopper 7. The internal pressure is introduced into the clearances through a pressure eqalizing hole 12, which functions for pressing the retainer 6 onto the inside of a casing and the end cover by way of packing.
