Abstract
A valve for a fuel cell system includes a valve housing having a valve seat formed therein. The valve seat includes an orifice formed therein to permit a fluid to flow through the valve housing. A movable member is disposed in the valve housing and is movable between an open position and a closed position. The movable member includes a first end having an elongate portion and a generally conical shaped base. At least a portion of the base is disposed in the orifice of the valve seat when the movable member is in the closed position to militate against a formation of ice across the orifice of the valve seat.
Claims20
A valve for a fuel cell system, comprising:
- a valve housing including a valve seat formed therein, the valve seat having an orifice formed therein to permit a fluid to flow through the valve housing;
- and
- a movable member disposed in the valve housing and linearly movable between an open position and a closed position, wherein at least a portion of the movable member is disposed in the orifice to militate against a formation of ice across the orifice of the valve seat when the movable member is in the closed position.
A valve for a fuel cell system, comprising:
- a valve housing including a valve seat formed therein, the valve seat having an orifice formed therein to permit a fluid to flow through the valve housing;
- and
- a movable member disposed in the valve housing and movable between an open position and a closed position, the movable member including a first end, a second end, and a collar disposed intermediate the first end and the second end, the first end having a base, wherein at least a portion of the base is disposed in the orifice of the valve seat when the movable member is in the closed position, and wherein a fluid tight seal is formed between the collar and the valve seat when the movable member is in the closed position.
A valve for a fuel cell system, comprising:
- a valve housing including a valve seat formed therein, the valve seat having an orifice formed therein to permit a fluid to flow through the valve housing;
- and
- a movable member disposed in the valve housing and linearly movable between an open position and a closed position, the movable member including a first end, a second end, and a collar disposed intermediate the first end and the second end, the first end having an elongate portion and a generally conical shaped base, wherein the base is positioned away from the orifice of the valve seat when the movable member is in the open position so as to not interfere with a flow of the fluid through the orifice, and at least a portion of the base is disposed in the orifice of the valve seat when the movable member is in the closed position to militate against a formation of ice across the orifice of the valve seat, and wherein a fluid tight seal is formed between the collar and the valve seat when the movable member is in the closed position.
