Air purging fuel valve for turbine engine |
摘要 |
An air purge/fuel valve for a turbine engine uses a spool configuration to provide both a more reliable check valve system preventing backflow into the fuel line or the air purge line and a mechanically positive prevention of simultaneous gas and air flow, together with the features of a pneumatically actuated valve in which an external pneumatic actuator positively moves the valve spool against possible resistance of the spool caused by minor coking.
