Abstract
A solenoid valve has an elastomeric annular disc placed between the stationary and the moveable armatures. The elastomeric disc operates to absorb axially transmitted loads to quiet the operation of the solenoid valve. The solenoid valve also includes a pair of elastomeric rings surrounding the movable armature and being located between the lower armature and the coil assembly of the solenoid valve. The elastomeric rings operate to absorb laterally transmitted loads to quiet the operation of the solenoid valve. In another embodiment of the invention, the elastomeric rings are replaced with longitudinally extending elastomeric ridges located between the movable armature and the coil assembly. In this second embodiment, the elastomeric ridges may be integral with the elastomeric disc.
