ABSTRACT:
An injector mounting arrangement includes a tolerance ring assembly that provides damping or absorption capabilities in addition to alignment and centering functionality. The tolerance ring assembly is designed to absorb axial excitation energy from the injector by converting it into strain energy through the radial deformation of the tolerance ring. The strain energy is absorbed in the form of bending stress within the tolerance ring more effectively than by simply absorbing the axial forces in compression alone. As a result, vibration and noise is reduced and/or isolated.
