ABSTRACT:
The backlash spring of a fuel control linkage is enclosed by an elastomeric sleeve which absorbs the energy of multiple resonant modes stimulated in the spring by vibratory fields. Deflections of large amplitude in the spring are minimized thereby. The sleeve has a plurality of ribs which extend axially therein and which provide an interference fit with the coils of the spring. The sleeve ribs contact as many of the spring coils as possible but minimize interference of the sleeve with the motion of the spring during the normal articulation thereof.
