ABSTRACT:
A seal includes a first seal retainer, a seal holder and a second seal retainer. A somewhat cup-shaped recess of the first seal retainer opens in a first direction of motion of a movable member against which the seal is to seal. The seal holder includes a first somewhat cuplike portion adjacent to the first seal retainer and a second somewhat cuplike portion more remote from the first seal retainer. The first somewhat cuplike portion opens in a second direction of motion opposite the first. The second somewhat cuplike portion opens in the first direction. The second seal retainer includes a first portion closer to the seal holder and a second portion more remote from the seal holder. The second somewhat cuplike portion of the seal holder receives the first portion of the second seal retainer.
