Abstract

In the mechanical packing the pressure that forces the disc rotating with the shaft against the disc which may be axially moved along a fixed support, is conveyed by a hollow, toroidal shape pneumatic seal made in soft flexible material. The pressure regulation controls the inflation of the pneumatic seal proportionally. The pneumatic seal is lodged inside an annular groove, axial in relation to the rotating shaft, in a fixed support. The valve controlling pressurization passes through the support to which the seal is attached. The outer contact surface of the seal has annular grooves.
