With these and other objects in view, the in-. vention consists of certain novel features of con struction, as will be more fully described and par ticularly pointed out in the appendedclaims. In the accompanying drawings: Fig. 1 is a diagrammatic view illustrating in section apart of an internal combustion engine and also illustrating a plurality of filter units any number and hooked up in parallel relation. y Each of’these iilter units as shown in greater. detail in Fig. 3 comprises a casing ~22 oi.’ a suitable cross sectional shape, the shape here shown being for illustration cylindrical, with an inlet opening 23 at'one end and a similar open ing 24 adjacent' its other end. AA cover 24' for this case is provided and may be held in place by a _bolt 25 which threads into a center tube 26 about which the removable cartridge-21 is located. This cartridge -21 is of a shape`v similar to the . casing having perforations in .its cylindrical wall v ` connected in parallel with relation to the oil _sump 28 while its ends are imperforate and are sealed 40 with the tube 26 so that oil cannot pass into the of the engine; Fig. 2 is a view taken on substantially line 2--2 center tube at either end of- the cartridge.
