METHOD OF REPAIRING A SEAL STRUCTURE IN A HYDROMECHANICAL ACTUATOR

摘要

A static seal structure is disclosed in which the space between a casing and a sleeve is subdivided into several chambers by the seal between an O-ring mounted on the sleeve and a seal element mounted within a groove formed in the casing. The casing may be formed with a smooth interior surface and the groove may be formed in this surface such that it has a generally rectangular cross-sectional shape opening toward the sleeve. The seal element is mounted in the groove and has a portion which extends outwardly beyond the groove toward the stationary sleeve. The O-ring mounted on the sleeve contacts the seal element to provide a fluid-tight seal between the adjacent chambers.
