DEVICE FOR SEALING BETWEEN THE MOBILE ARRANGEMENTS OF AN ARTILLERY BRAKE BRAKE

摘要

The technical sector of the invention is that of sealing devices between a piston rod and a cylinder of an artillery recoil brake. /P P The piston delimiting a high pressure chamber in the cylinder 4 and a low pressure chamber 5, chambers whose respective variable volumes are determined by the relative piston / cylinder position. The sealing device according to the invention is characterized in that it comprises a so-called medium pressure chamber 11, through which the piston rod passes and which communicates with the high pressure chamber by a substantially annular channel surrounding the piston rod, and in that the medium pressure chamber 11 is connected to the low pressure chamber by a conduit 12, the section of which is greater than that of the annular channel. /P P Application to artillery equipment.
