ABSTRACT:
A fluid filtering device is provided for use with a fluid system having a fluid reservoir at least partially filled with fluid. The filter device comprises a housing which is submerged within the reservoir and has a fluid port. An elongated filter assembly comprising a tubular filter element open at one end and a holder assembly secured to the other end of the filter element is insertable into the reservoir so that the open end of the filter element sealingly engages the submerged housing. A fluid passage through the housing fluidly connects the fluid port with the interior of the filter element. A stopper is formed on the free end of the holder assembly so that the entire filter assembly can be inverted and reinserted into the reservoir whereupon the stopper prevents fluid flow through the fluid passage permitting the servicing of other system downstream of the filter assembly without it being necessary to drain the reservoir.
