Multicontact Flexible Seal

An H-shaped cross-section flexible seal is used to form an airtight joint between two members.

The figure shows the seal 1 in place between a machine cover 2 and a base plate 3. The cover 2 has at its sealing edge an inner sealing wall 4 and an outer protective shroud 5. The seal 1 is located in a tapered groove 6 in the base plate 3, with the inner wall 4 of the cover 2 positioned between the two upper legs of the seal.

When the cover 2 is lowered into place, the H-shaped seal 1 is distorted to provide multiple contacts with the inside walls of the groove 6. The vertical compression of the seal 1 also tends to move the upper legs of the seal towards one another, thereby gripping the inner wall 4 of the cover 2.

Excessive compression of the seal 1 is limited by the outer shroud 5 which abuts the base plate 3 and serves as a depth stop, as well as protecting the otherwise exposed portion of the seal. The seal 1 is moulded from a closed-cell material in one piece to eliminate jointing and to skin the surface of the seal.
