SEALING ARRANGEMENT

摘要

A sealing arrangement includes a first member having a non-circular hole, a second member having a non-circular and annular groove that extends continuously around an outer circumference of the second member, and a seal made of an elastic material and seated in the groove. An outer circumference of a body of the seal is in contact with a wall of the first member defining the non-circular hole, and an inner circumference of the body of the seal is in contact with a wall of the second member defining the groove. At least one protrusion protrudes from at least one portion of the body where a relatively low contact pressure is applied between the body and the groove and along a direction of insertion of the second member into the first member.
