SEALING DEVICE

摘要

PURPOSE: A sealing device is provided to improve intensity of a filter receptive frame in the sealing area of filter element and then increase sealing quality of an inlet more than an outlet. CONSTITUTION: The sealing device contains a filter element(1) partly covered by a filter receptive frame(2) and the front of the filter element contains a sealing element(3). The sealing element contacts to the filter receptive frame under an elastic initial stress in a sealing way. The front of the filter receptive frame which faces to the sealing element, opens in the filter element direction, has a closed U-shaped profile in a circumference direction, forms an inner ridge(5) of the profile with a sealing seat edge(6) and contacts the inner ridge to the sealing element in the sealing way.
