Water separator
Abstract
Abstract A WATER SEPARATOR FOR A DIESEL FUEL SUPPLY SYSTEM PROVIDES A PLENUM CHAMBER HOUSING A WATER SEPARATOR BARRIER MADE OF RIBBED-KNIT POROUS CLOTH IN THE FORM OF A CYLINDRICAL SOCK HAVING A CLOSED END. THE OPEN END OF THE SOCK IS SEALED AROUND THE INLET PASSAGE OF THE SEPARATOR SO THAT FLOW MAINTAINS THE SOCK INFLATED FOR FLOW THROUGH THE ENTIRE POROUS SURFACE AREA OF THE SOCK. THE PORES OF THE SOCK ARE SMALLER, WHEN RELAXED, THAN THE WATER DROPLETS TO BE SEPARATED AND THE SOCK IS MADE OF NYLON WHICH IS NOT WETTABLE BY WATER. THE PORES OF THE SOCK ARE EXPANDABLE AS REQUIRED TO ACCOMMODATE VARYING FLOW RATES WITH A MINIMUM CHANGE IN PRESSURE DIFFERENTIAL ACROSS THE SOCK AND TO PERMIT THE PASSAGE OF LARGE WAX PARTICLES UNDER LOW TEMPERATURE OPERATING CONDITIONS TO PREVENT CLOGGING.
