AIR RELEASING METHOD OF HYDRAULIC CYLINDER

摘要

PROBLEM TO BE SOLVED: To provide an air releasing method of a hydraulic cylinder capable of being easily and inexpensively applied to a new or existing device and surely executing air releasing work in safety without needing high technology. SOLUTION: In this method of releasing the air mixed inside of an appliance such as a cylinder utilizing oil pressure, the remixing of the air caused by a negative pressure generated in dipping a hose having a predetermined length into the oil in a container, is prevented. The predetermined length means a distance to make the pipe conduit resistance of the oil generated in the hose be higher than the negative pressure generated in the cylinder.
