Abstract

PURPOSE: To provide a hydraulic operation system which will not give effect on the postulated operation timing of its controlling object even if the altitude changes, by installing an altitude compensation valve device, and maintaining the hydraulic pressure, which works as a control signal, at a constant valve regardless of altitude changes.
