FLAP FOR BLOCKING A FLUID DUCT FOR AN AUTOMOBILE

摘要

The assembly has a driving shaft guided in rotation by a driving portion (311) of the shaft trunnion-mounted in a rotative guiding bearing i.e. ball bearing. The shaft is extended from the portion (311) to an end portion (302) of the shaft. The end portion is covered by a cover (320) at a side of a closing valve (200) of a fluid conduit, and is rotatingly connected to the shaft. The cover is trunnion-mounted in another rotative guiding bearing having same cradle diameter as of the former bearing. Identical sealing units i.e. elastomer rims, are mounted on the shaft and the cover, respectively. An independent claim is also included for a method for assembling a closing valve in a fluid conduit in which openings for the passage of a driving shaft of the closing valve are formed.
