Abstract
The exhaust coupling of the invention comprises a first length of tubing having a first assembly flange fixed thereon, a second length of tubing associated with a second assembly flange, clamping means disposed to urge the assembly flanges towards each other via first resilient members, and second resilient members disposed between the assembly flanges in order to be compressed therebetween and to exert a force on the flange which is less than the opposing force exerted thereon by the first resilient members.
Claims4
A flexible exhaust coupling comprising a first length of tubing having one end on which is mounted a resilient annular gasket having a convex spherical bearing portion, a first assembly flange associated with the first length of tubing, a second length of tubing terminated by a concave spherical bearing portion facing the convex spherical portion of the resilient annular gasket, a second assembly flange associated with the second length of tubing, and a clamping means, including a first resilient member, disposed to urge the assembly flanges towards each other and to tighten the gasket and resilient means compressibly disposed between the assembly flanges for generating a force opposite to and less than a force generated by the first resilient member so as to reduce the force on the flanges when the clamping means is tightened and avoid crushing of the annular gasket while maintaining the sealing of the coupling.
