Sealing arrangement

A sealing arrangement for a two-member couple, comprising a sealing ring interposed between the two members of the couple and having a face engaging one of said members and a first surface bounded by two axially spaced edges;

• a resilient ring of elastomeric material interposed between the other member of said couple and said sealing ring, said resilient ring having a second surface being in contact with said first surface of said sealing ring;
• and a groove formed in said other member, open outwardly away toward said one member of the couple and adapted to accommodate said sealing ring and said resilient ring, said first surface of said sealing ring being axially inclined from said one edge toward the other, said second surface of said resilient ring being axially inclined to conform with said first surface, said sealing ring and said resilient ring being arranged in said groove in compressed relationship so that said resilient ring permanently exerts a biasing force upon said sealing ring adjacent to one of said edges to thereby press said face of the sealing ring into tight sealing engagement with said one member.
