Abstract
An annular element which is stationary under normal operating conditions is interposed between a stationary sleeve and a central rotary plug. The annular element is provided with peripheral passages and radial openings, said radial openings being located in the line of extension of bores formed in the stationary sleeve. In the event of accidental seizure of the rotary plug, the annular element is automatically released and driven in rotation, thus permitting progressive transfer of the hydraulic fluid from one bore of the stationary sleeve to the adjacent bore via the peripheral passages.
