Solenoid-Powered Gate Valve

摘要

A solenoid-powered gate valve that provides a reliable, high quality seal with a reduced operating force requirement. The valve includes a solenoid coil and armature connected to a valve mechanism, with the valve mechanism including a conduit having a connection opening, an oppositely-disposed pocket, and a sprung gate assembly linearly movable between the connection opening and the pocket. The sprung gate assembly includes a first gate member with an opening, a second gate member with an opening, and an endless elastic band retained between the first and second gate members, with the openings and endless elastic band collectively defining a passage through the sprung gate assembly, with the first and second gate members being mechanically coupled to the armature for reciprocating linear movement between the connection opening and the pocket. The endless elastic band allows an interference fit within the pocket with reduced frictional opposition to gate movement.
