ABSTRACT:
A solenoid valve mechanism including a valve housing with a vent port and a pressure supply port, a ball valve in a valve seat in said housing controlling pressure distribution to a control pressure passage from the supply port, a solenoid armature adapted to activate the ball valve, and a spring valve seat that cushions the operation of the valve mechanism when it is activated. Other mechanisms for reducing vibrations and noise of a solenoid valve mechanism include Belleville springs, O-rings, coil springs, foam cushions, and the like. The valve mechanism can be either normally applied or normally vented.
