PILOT VALVE OF FUEL NOZZLE

摘要

FIELD: machine building.SUBSTANCE: application gives description to a pilot valve having a bush-like shutoff element which is set so that to be able of axial displacement at a guiding rod with one end of the latter resting against a stationary part. The other end of the guiding rod is periodically loaded by high pressure in the course of fuel nozzle operation. Such high pressure is used at the stage of fuel nozzle testing for the purpose of plastic deformation of the stationary part resulting in a recess-like backup indentation for the other end of the guiding rod.EFFECT: improved design.8 cl, 1 dwg
