Abstract
A sealing device for a sleeve of washing machines, comprising a first, stationary, annular screen, and a second, rotatable, annular screen. The first annular screen includes a first cylindrical mounting portion and a first flange portion; and the second annular screen includes a second cylindrical mounting portion and a second flange portion. The sealing device is characterized in that both the first and the second annular screens include the same number of non-contacting sealing lips, which are similar to each other and contained axially between the first and second flange portions, in radially alternating positions axially arranged one above the other, so as to define a sealing labyrinth (L). The first and second annular screens define between them a discharge chamber (C) and an obstruction chamber (C) which are arranged along the sealing labyrinth (L), substantially at opposite ends of the said sealing labyrinth (L).
