ABSTRACT:
An annular composite two-piece seal is described for sealing engagement with a reciprocating member. The composite seal includes a soft, flexible, annular sealing ring having an annular sealing lip with a chamfered portion facing the high pressure side of the seal and inclined toward the reciprocating member, and having an axially and circumferentially extending wall for sealing engagement with an axially directed circumferential wall of a groove in a stationary member receiving the seal. A second annular sealing ring of harder and lower friction material is formed with a circumferentially extending sealing lip for engaging the reciprocating member. Both of these sealing lips seal with the reciprocating member at a low pressure loading of the seal. The sealing lip on the second ring is deflected into tighter sealing engagement with the reciprocating member with increased pressure on the first ring. Mating interlocking portions on these rings prevent substantial displacement therebetween and thus reduce the likelihood of bypass leakage between the rings.
