  • Publication number: 20050121089
    Abstract: 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.
