ABSTRACT:
A multiple-disc type fluid filter is described wherein the housing includes an outer tubular section, and an inner section having two tubular members with an end plate at one end of one tubular member and securable to an open end of the outer housing section. The two tubular members of the inner housing section include ribs for supporting the filter discs. The end plate and the tubular member to which it is secured are open and constitute one of the filter ports, e.g. the inlet port, and the opposite end of the same tubular member is closed and terminates short of the outer housing section. The second tubular member, which is longitudinally spaced from the closed end of the first tubular member, constitutes the other filter port, e.g. outlet port. The stack of filter discs are all of substantially the same uniform thickness, but there are included a plurality of further discs of non-uniform thickness such as to correct the accumulation of non-uniformities in the latter discs.
