ABSTRACT:
The technical field of the present invention is that of sealing devices between a piston rod and a cylinder of an artillery recoil brake. The piston divides the chamber into a high-pressure chamber and a low-pressure chamber. The volumes of the chambers vary according to the position of the piston relative to the cylinder. The sealing device according to the invention includes a "medium-pressure" chamber through which the piston rod passes, and which communicates with the high pressure chamber by means of a roughly annular channel surrounding the piston rod. The medium-pressure chamber is connected to the low pressure chamber by a pipe having a cross sectional area greater than that of the annular channel. The device is intended for applications to artillery material.
