ABSTRACT:
A fuel-water separator comprises a container having entry and exit ports and a progression of spaces through which the fuel moves. The spaces become progressively smaller and are arranged to direct the fuel through a series of downwardly and upwardly directed paths. The lower density fuel moves upwardly while the higher density water tends to move downwardly to drain through drainage openings provided in the lower portions of the spaces. Valves are provided for closing the drainage openings. The valves include float-valve balls which will release the water but hold the fuel. One of the spaces in the container includes a media having a downwardly directed surface upon which the water coalesces to move downwardly and through which the fuel moves to progress to the next space. Another one of the spaces includes a media providing a surface tension-discriminating surface through which the fuel will move and down which the separated water will move. The fuel entering the separator may move first through a generally circular passageway having a radially outer wall with openings through which the water is separated by centrifugal force.
