Abstract
A seal is provided between a pair of members by a flexible seal element fixed to one member and having a turned edge. The seal element overlies a contact surface of the other member to effect the seal, the seal element spanning a gap between the members and being pressed into the contact surface by a high pressure region on the same side of the gap as the sealing element. In other forms, a second sealing element is employed in conjunction with a spline seal forming a tortuous sealing path between the members.
