ABSTRACT:
A bellows-type spring seal has a flexible bellows with an upper sealing end adapted to mate with a bell housing of an air intake pipe. The seal provides an effective breakaway joint when the cab is tilted forward from over the engine. A means, such as coil springs, encircles the bellows to push upon the underside of the sealing end of the bellows to provide a positive preload sealing force. The seal is self-aligning in the vertical and horizontal planes to accommodate cab rocking and minor misalignment in manufacture of the truck.
