Housing unit for liquid gauge and strainer

Claim 1

A housing unit for use in a liquid reservoir, adapted to unitize a liquid level gauge, liquid suction pipe, strainer, and housing, comprising a housing having at least two chambers, said at least two chambers including a generally cylindrical first chamber open at one end and substantially closed at the other end and a generally toroidal second chamber concentric with said first chamber, said second chamber adjacent to and encircling the substantially closed end of said first chamber, said second chamber having an annular opening adapted to receive a filter element therethrough and an annular lid adapted to close said opening while positioning a filter element within said second chamber, a cover adapted to be removably attached to and close the open end of said first chamber and removably suspend said housing unit within said reservoir, said first chamber adapted to contain a liquid level gauge and said second chamber adapted to contain a strainer, means within said first chamber for guiding a movable portion of the liquid gauge, said strainer including a filter element adapted to be confined within said second chamber by said annular lid, at least two openings in said first chamber for permitting passage of a liquid and air into and out of said first chamber, and second chamber having a first opening for admitting liquid into the chamber on one side of said filter element and a second opening for permitting the insertion of one end of a liquid suction pipe on the other side of the filter element, said filter element adapted to embrace an open end of the liquid suction pipe inserted therein, whereby the movable portion of a liquid level gauge contained within said first chamber is unrestricted when moving from the end closed by the cover to the substantially closed end thereby permitting said liquid level guage a range of indication which extends to the substantially closed end of said first chamber.
