Abstract
A valve for a fuel cell system includes a main body having a passage through which a fluid is permitted to flow. A sliding member is disposed in the main body and configured to move between an open position and a closed position. The sliding member has an orifice formed therein. At least one biased plug is disposed within the main body adjacent the sliding member. The biased plug abuts an outer surface of the sliding member and permits fluid flow through the orifice of the sliding member when the sliding member is in the open position. The biased plug seals the orifice of the sliding member and militates against a formation of ice in the orifice when the sliding member is in the closed position.
