Filed: 1953-03-20
Abstract: 720,831. Filters. FRAM CORPORATION March 20, 1953. No. 7770/53. Class 46. A filter cartridge of generally annular shape including an axially-extending tubular core has means to seal its end walls around the central tube of a filter casing and means, for example holes in the tubular core, to conduct liquid to filtering material in the cartridge, and means, for example holes in one end wall, to conduct filtrate out of the cartridge. In the complete filter shown, liquid entering at 19 passes out through holes 40 in a centre tube 18 into a space 41 and thence through a hole 44 in the tubular core 31 of a filter cartridge 25. The hole 44 leads into a pocket 43 formed in the lower end wall 29 of the cartridge, whence the liquid passes between ribs 45 in the end wall to a space 66 between the cylindrical wall 26 of the cartridge and a stack 57 of discs each provided with lobes, spaces and spokes located more or less alternately. Adjacent discs are displaced 60 degrees to provide contaminant-collecting pockets. The central hole of each disc is starshaped so that filtrate conduits 56 are provided along the axis of the stack, whence the filtrate passes to a pocket 61 formed in the upper end wall 27. From this pocket the filtrate passes out of holes 63 into the outer casing 10 and from there through an opening 17 in the wall 11. The pocket 43 is sealed from the filtrate conduits 56 by a gasket 47 on a plate 46 urged upwards by a spring 62 to ensure close contact between the topmost disc of the pack and the upper end wall 27. The core 31 is sealed around the centre tube 18 by washers 34 and 36 and the cartridge rests on abutments 38.
