ABSTRACT:
A valve has an annular seat member coaxially mounted in a groove in the valve body around the outlet passageway. The groove has parallel sides which are perpendicular to its bottom. The seat member has a lesser radial thickness than the groove and is mounted in the groove in an uncompressed condition with substantial clearance between the sides of the seat member and the adjacent sides of the groove. A lip about the outer face of the seat member adjacent its inner periphery normally contacts the adjacent valve member in sealing relation. The portion of the seat member which fits within the groove has an inclined inner annular portion that does not contact the groove bottom and an outer resting surface which contacts the groove bottom. The seat member is formed of a deformable material with the lip being deformed when the seat member is loaded in compression as the valve is assembled. Upon loading the seat member it pivots about an outer corner located at an outer peripheral portion of the annular resting surface portion and it deforms a limited amount so sides thereof contact adjacent sides of the groove.
