  • Reduced noise solenoid valve
    Patent number: 5775670
    Abstract: Modified pole piece and armature members reduce the noise level for purge valves, particularly at low temperatures. A raised outer ring positioned on the lower end of the pole piece mates with a raised step on the upper end of the armature. Alternatively, a noise disk made from a flexible energy absorbing material, such as fluorosilicone, could be positioned between the pole piece and armature; also the valve member positioned on the lower end of the armature could be made from the same material.
