A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member, with the solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion extending from the body portion. The body portion is adapted to be removably coupled to the solenoid connecting member, and the securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of the retaining bracket.

A pulse width modulated solenoid system having low noise characteristics is described. Noise reduction is primarily achieved by separating the solenoid device from the insulator and the manifold housing through the use of rubber isolators and multiple sets of o-rings, thus preventing metal to metal contact. Additional noise reduction is achieved by encapsulating all of the solenoids, using the insulator, the cover plate, the housing, and the screen carrier. Noise levels are also further reduced by minimizing the impact force of the armature against the sleeve by allowing fluid to vent into the upper area of the sleeve, thus causing a dampening effect.
