ABSTRACT:
Vibration absorbing connector for use in high pressure fluid piping systems such as the refrigerant lines in an automotive air conditioning system incorporates a thin bellows member whose ends are restrained against axial movement by a restraining means such as a plurality of axially extending flexible cables or a braided metal sleeve which surrounds the bellows member. A molded-in-place elastomeric layer fills in the external bellows corrugations to prevent their deformation under load and encapsulates the restraining means. The design permits a 3 inch long bellows having a 0.005" wall thickness to perform as well as a 7 inch long bellows having a 0.020" wall which has a conventional configuration under internal fluid pressures that would collapse the thin wall bellows corrugations in the absence of the elastomeric layer.
