<p>Modified pole piece (50) and armature (52) members reduce the noise level for purge valves, particularly at low temperatures. A raised outer ring (80) positioned on the lower end of the pole piece (50) mates with a raised step (82) on the upper end of the armature (52). Alternatively, a noise disk made from a flexible energy absorbing material, such as fluorosilicone, could be positioned between the pole piece (50) and armature (52); also the valve member (48) positioned on the lower end of the armature (52) could be made from the same material.</p> |
