Fuel valve assembly

Fuel valve assembly

A valve assembly ( 10 ) comprises a valve body ( 20 ), a first valve ( 22 a), a second valve ( 22 b), and a manual override device ( 24 ). The valve body ( 20 ) defines a first inlet ( 30 a), a second inlet ( 30 b), and an outlet ( 32 ). Each valve ( 22 a /22 b) includes a plunger ( 68 a /68 b) that...

Beschreibung
Zusammenfassung:A valve assembly ( 10 ) comprises a valve body ( 20 ), a first valve ( 22 a), a second valve ( 22 b), and a manual override device ( 24 ). The valve body ( 20 ) defines a first inlet ( 30 a), a second inlet ( 30 b), and an outlet ( 32 ). Each valve ( 22 a /22 b) includes a plunger ( 68 a /68 b) that is electrically movable between a position whereat the corresponding inlet ( 30 a /30 b) communicates with the outlet ( 32 ) and a position whereat the inlet ( 30 a /30 b) is sealed from the outlet ( 32 ). The override device ( 24 ) is manually movable to override positions whereat the electrical control of one of the valves ( 22 a /22 b) is overridden and the plunger's seat-sealing surface ( 72 a /72 b) is caused to move so that the corresponding inlet ( 30 a /30 b) communicates with the outlet ( 32 ).
