Abstract

1492431 Valves NEIL & SPENCER Ltd 21 Jan 1976 [1 Feb 1975] 4456/75 Heading F2V [Also in Division B1] A filter in a dry-cleaning machine comprises a housing 8 enclosing one or more inward-flow filter cartridges and having an inlet/drain port 12 connected to a two-way valve 20, an outlet port 10 connected to an on/off valve 16, and an air vent valve 32 (Figs. 3, 4, not shown), containing a nylon float which allows air to flow into or out of housing 8 but prevents liquid solvent from leaking out. Valves 16 and 20 are linked together and operated by one handle 26 so that in a first position solvent flows from conduit 2 through the cartridge(s) to conduit 6, and in the second position valve 16 is closed and solvent drains from the housing to conduit 4. A housing door (13) is then opened and the cartridge(s) changed. The valves are restored to the first position so that the housing fills with solvent, air being displaced through valve 32, and solvent thereafter exits to conduit 6. Fig. 1 (not shown) illustrates three filters connected in parallel, the drain conduits 4 and vent conduits 34 leading to a common sump (44). (For Figures see next column.)
