Abstract (en)
[origin: US2008017643A1] The invention relates to a ventilation device, particularly for fluid-storing reservoirs such as tanks, comprising a connecting part ( 1 ), which can be attached to the opening of the reservoir and which serves to form an air- and/or fluid-conducting connection between the inside of the reservoir and the surroundings. This connection is effectively sealed off by means of a labyrinth-like seal consisting of a system of seal passages ( 53, 59, 69, 73 ) at least from the penetration of media such as water and/or cleaning chemicals but is not sealed off from an exchange of air for the actual ventilation. In addition, a filter element ( 61 ) is placed inside the connection. At least a portion of the seal passages ( 59, 69, 73 ) are formed on a ventilation chamber ( 41 ), which can be releasably attached to the connecting part ( 1 ) and which has a seat ( 79 ) for the filter element provided in the form of a filter leaf ( 61 ), in which the filter leaf ( 61 ) is held in such a manner that it forms, with at least a portion of both of its broadsides, a partition between two successive seal passages ( 59 and 69 ) adjacently extending in principal directions that are at least approximately parallel to one another.
