Abstract: 1,239,068. Filter. BOWSER Inc. 29 Nov., 1698 [4 March, 1968], No. 56763/68. Heading B1D. [Also in Division F2] A filter comprising a plurality of inwardflow filter cartridges clamped into engagement with respective apertures in a tube plate 28, dividing their common housing (Fig. 1, not shown), has spring-loaded valves which close the apertures when corresponding cartridges are withdrawn or incorrectly inserted. Fig. 2 shows a valve, whose body 52 is sealed into an aperture in plate 28, with axially movable valve sleeve 66 closing the outlet openings 86, annular gaskets 62 and 64 engaging seats 56, 58 above and below the openings. The lower end of a filter cartridge engages crossbar 84 to depress the valve sleeve, when the cartridge is inserted in the upper end of the valve body (Fig. 3, not shown). Ports 88 equalise pressures on the two ends of the valve sleeve, and the relative areas of gaskets 62, 64 ensure a net upward force on sleeve 66 when the valve is closed. Fig. 4 (not shown) illustrates an alternative valve with outlet openings in a single frusto-conical seat. The tops of the cartridges are engaged by pins (42) on clamping plate (44). When assembling the valve, sleeve 66 is inserted in the body before lower closure disc 78 is sealed into place.
