A resin lip type seal having a first inner seal lip, a first outer seal lip, and a second inner seal lip that are formed integrally with each other.

A lip seal is provided on each side of the annular diaphragm seal.

The case bears a lip seal as a primary seal (97).

The flange also has a lip seal (40) thereon.

The lip seal (20) is biased to an operative, sealing position by a spring (78) or a counterweight (94), so as the lip (26) extends to its operative position, so does the lip seal (20).

The shaft seal has a mounting portion configured to be connected to a stationary housing and a seal lip having an annular sealing surface extending between an oil side end and an air side end of the seal lip.

When the lip (26) moves from its extended, operative position to its stored position, the lip forces the lip seal (20) to move underneath the deck (30).

The first lip seal member has a tubular section, a radial section, a seal lip, and a flange section.

At least one second space for receiving hydraulic fluid is defined between the lip seal and a region of the membrane opposite the lip seal.

A lip seal (11) is mounted on the seat (9).

The seal is preferably an X-ring or a lip seal with necessary back-up rings.

The lip seal engages an adjacent portion (86) of the crankshaft.

Upon movement of the barrier member or deployment sleeve to a position exposing the Hp seal to the shaft, the o- ring urges the lip seal into engagement with the outside diameter of the shaft.

A lip seal has an internal spring element disposed in an elastomeric ring.

An annular bridge portion connects the seal lip to the mounting portion.
