Abstract
Abstract A device for mounting a filter element is located in a housing. The housing is sealed on its outside wall in contact with a mounting member. The mounting member is mounted on an inside partition of the container by a sealing connection. This sealing connection has a sealing element inserted between sealing surfaces of the mounting member and the inside partition. A holding device for fixing the position of filter element in the housing incorporates a pressure element which engages the filter element to secure the filter element against rotational movement relative to the housing.
