Abstract

"IMPROVEMENTS INTRODUCED IN THE OBJECT OF THE MAIN PATENT No. 389,732, by: SEALING DEVICE FOR DRYER OR ROTARY TUBULAR REFRIGERATOR OR ANALOGUE APPARATUS", intended to ensure the tightness between a first cylindrical element, circular section, adapted to a second element and animate of a movement of rotation around its axis with respect to the latter, and involving two annular joints arranged in series between the interior of these elements and the exterior, and determining an annular chamber limited by such joints in which the pressure is maintained at a value close to the pressure that reigns inside the elements, in their adaptation zone, characterized in that the outer seal is formed with a series of flexible metal sheets that overlap in the manner of scales fixed to one of the elements and resting elastically on a cylindrical surface of the other element, and because the inner seal is c Composed of at least two annular walls, parallel to each other and fixed respectively to the first and second of the elements, at a small distance from each other, so that they form a narrow passage between the interior of the elements and the camera. cancel.
