Abstract
A seal member of elastomeric material which is shaped to fit sealably within a recess of a flow diverter body. On the inside of the diverter body, a seal is effected against a slidable cylindrical valve sleeve. On the outside of the diverter body, a seal is effected against a permanent housing. The seal is constructed with an outer section having a generally circular opening, an inner section having an oblong opening and a connecting section between the outer and inner section having a bore therein connecting the circular opening with the oblong opening. A rigid support member embedded in the elastomeric material provides rigidity and strength to the seal member.
