FUEL-FEED SYSTEM FOR AN AIRCRAFT ENGINE

摘要

A fuel-feed system for an aircraft engine is provided with a filter, and inlet and outlet piping coupled with the filter. A differential pressure transmitter is coupled with the filter for sensing a pressure build-up when ice deposits on the filter in flight. Return piping is provided for passing fluid into a nozzle spaced proximate the filter. A shut-off valve is coupled with the transmitter and is connected in the return piping to pass fluid to the nozzle when signaled by the transmitter.
