ABSTRACT:
A device which may be connected to a liquid supply line for use in separating a foreign liquid and particulate matter contained in a supply liquid, wherein the foreign liquid has a specific gravity greater than that of the supply liquid. The device is particularly suitable for separating water and dirt particles from a liquid fuel. The device includes: a generally cylindrical housing containing a settling chamber having a settling zone at a lower region of the housing and a displacement zone at an upper region of the housing; an outlet chamber surrounding the settling chamber in the upper region of the housing; an inlet located tangential to the housing and leading into the settling chamber; an outlet leading from the top of the outlet chamber; a cylindrical filter screen which separates the settling and outlet chambers and which defines flow paths connecting the settling chamber with the outlet chamber so that liquid passing through the chambers from the inlet to the outlet passes through the filter screen from the interior to the exterior thereof; and detecting means including a float warning mechanism for detecting the presence of a predetermined level of foreign liquid in the settling chamber. The device provides for rotational flow of liquid and includes features which result in a minimum amount of interference with the quiet zone that exists in the center of a rotating body of liquid, thus contributing to maximizing the opportunity for separation of water and dirt from a liquid fuel.
