Flow channel e.g. air flow channel, sealing unit for e.g. floor vacuum cleaner, has two sealing arms provided in attachment area, where arms spaced to each other are bent for sealing reinforcement with high and/or low pressure

摘要

The unit (A) has two sealing arms (18, 19) provided in an attachment area in a cross-section in an axial direction of a flow channel. The arms are bent for sealing reinforcement with high and/or low pressure and are spaced to each other in a radial direction. An axial spacing between U-bars (14, 15) is provided for the formation of a mounting recess (21), where the U-bars are connected with each other and the unit is integrally formed as a single-piece. The U-bars and/or U-arms (16, 17) have a different radial and/or axial extension.
