Abstract

"SEALING DEVICE FOR OVEN, DRYER OR ROTARY TUBULAR REFRIGERATOR OR SIMILAR APPLIANCES", intended to ensure the tightness between a first cylindrical element of circular section, attached to a second fixed and animated element of a rotational movement on its own axis with respect to to the latter, and comprising two annular joints, located in series and arranged coaxially to the first element in the area of union with the other, and an annular chamber formed between said two joints in which the pressure is maintained with a value approximately equal to that of the pressure that prevails inside the first element, characterized by the sealing device in that one of the joints is formed of flexible metallic scales fixed to one of the elements and resting elastically on a first cylindrical surface of the other element, while the other seal is constituted by an axially sliding ring on a second cylindrical surface provided ta on one of the elements and applied against a surface of the other element located perpendicular to said second cylindrical surface.
