Oil level indicator for use with damping fluid metering pins

摘要

An oleo strut oil level indicator is provided which includes a rod slidably extending through a landing gear or other metering pin contacting the strut floating piston at one end and terminating at a frangible disc at the opposite end. Excessive oil loss in the strut produces a commensurate displacement of the floating piston toward the frangible disc, causing the opposite rod end to rupture the disc at a selected piston position and exposing a colored low oil level indicator to view thereby visually indicating a condition of potential danger.
