Abstract

Improvements in fluid filtering devices, for use with a fluid reservoir in which fluid is contained practically to a predetermined level, characterized in that each filtering device is formed by: an elongated tubular cylindrical main case having fluid outlet means formed in an extreme; means for securing the main box to the fluid reservoir, so that a part of the main box is located below the fluid level of the reservoir; fluid inlet means formed through the box to establish fluid communication between the tank and the interior of the box; an annular box element located coaxially in the main box below the fluid level of the reservoir, the box member being radially disengaged into the main casing and forming an annular chamber in between, the lower part of the box element being connected to the main housing so that the interior of the housing element opens the fluid outlet means, fluid passage means formed through the housing element to establish fluid communication between the annular chamber and the exit means and means to close the upper end of the box element; a filter assembly comprising a tubular filter element and means for locating the filter element in the annular chamber; and means for closing both upper and lower ends of the box element to the filter element.
