ABSTRACT:
An in-line fluid filter of the multi-piece type having a pair of body sections coaxially secured to each other. A filter element is fixedly disposed transversely across a filter chamber defined by the body sections intermediate a fluid filter inlet and outlet. This filter element includes an annular mounting flange interposed between mating annular body section end faces. A generally cup-shaped filter element support is fixedly located on at least the outlet side of the filter element and is dimensioned so that the filter element is at least partially received in the cup-shaped area thereof. This support includes an annular mounting rim which is also interposed between the body section end faces. The support allows the filter to experience greatly increased fluid pressure differentials across the filter element. The filter element mounting flange and the support mounting rim are dimensioned to at least extend to the outside diameter of the mating body section annular end faces. The body sections are rigidly affixed to each other at the end faces by means of a fusion type weld with at least a portion of the filter element mounting flange and the support mounting rim comprising a filler material for the weld to assist in producing a joint of high integrity. A pair of the filter element supports may be advantageously employed wherein the supports are in an opposed relationship to each other having the filter element positioned therebetween.
