Abstract
A base member has an exterior peripheral surface and has an interior chamber. An elastomeric band is stretched to fit over a portion of the peripheral surface and a portion of the band is allowed to extend beyond the peripheral surface of the base member so that the extension of the band is unrestrained and it thereby tends to reassume its relaxed position and while doing so, it forms a stable curl, or bight, about the edge of the peripheral surface. A plate is carried by a member which is relatively movable with respect to the base member, and the plate bears on the bight of the elastomeric band so as to form a sealed chamber within the base member while the plate is both rotated and moved toward and away from the base member; the bight of the elastomeric band being compliant to the movable plate, and tending to return to its stable position.
