Abstract

A filter unit comprises a first filter element 28, Fig. 1 (not shown), of relatively fine material and a second filter element 29 of relatively coarse material, and valve means 50 which prevents flow of liquid to be filtered through the second element except when a predetermined pressure drop across the first element is exceeded. The elements are annular, axially aligned, have perforated walls 30, 43, 40, and are divided by an annular plate 39 supporting the valve 50. Oil enters through an annular passage 14 and ports 18 in housing base plate 16, pressing aside resilient gasket 66, and enters annular space 27 around the elements. Oil passes through element 28 to central chamber 44 and outlet passage 12. When the first element 28 becomes clogged, oil pressure in central chamber 42 within element 29 forces valve head 50 from opening 45 in plate 39 against spring 49, thus allowing oil flow through the second element 29. When element 29 clogs, oil forces up member 59 of by-pass valve 38 against spring 62 and both elements are by-passed. Alternatively the bypass valve is of the same type as the valve 50 and is situated centrally at the end of the second element remote from the first element. This embodiment is not of the throw-away type as in Fig. 1, and the filter elements, enclosed in knitted fabric, together with the valves form a replaceable assembly. Air and sludge may separate from the oil outside an open-bottomed baffle surrounding the elements.
