In an automobile fuel system and particularly for a diesel powered vehicle, it is desirable to provide a water separator to prevent passage of water to the engine and particularly the fuel induction components. It is also desirable to provide ejection means for the separated water which may include a provision to prevent the ejected water from falling to the ground.

In a vehicle including an engine with an exhaust manifold, an automatic fuel-water separator and disposal assembly for series insertion in the engine fuel supply line, comprising: thin wall enclosure means defining a generally hollow interior space, the enclosure means having a generally elongate configuration with first and second end portions; fuel inlet and outlet means of the enclosure for connection to the fuel line at the first end portion to permit fuel to flow through the interior space; the second end portion of the enclosure means having a depending cylindrically walled portion axially projecting downward from the first portion for the purpose of collecting water which may be separated from fuel passing between the inlet and outlet; diffusion means between the fuel inlet and outlet to promote separation of water from fuel and to permit settling of water into the depending cylindrical portion of the enclosure means; a cylindrical piston valve encircling surrounded by the depending cylindrical portion of the enclosure means with a bottom surface movable therewith toward and away from the first portion of the enclosure means; yieldable means engaging the piston valve and normally holding it positioned toward the first end portion thereby defining a purge chamber for water beneath the bottom surface of the piston valve; the depending cylindrical portion defining a discharge opening located downward from the bottom surface of the piston valve for the discharge of water from the purge chamber; check valve means across the discharge opening to normally prevent the flow of water from the purge chamber but to permit such flow only when the bottom surface of the piston valve moves toward the check valve means which thereby decreases the volume of the purge chamber to eject the water; the piston valve having normally open passage means therein connecting the purge chamber with the interior space above the piston valve; the piston valve and cylindrical portion of the enclosure means being cooperative to close the passage means when the piston valve is moved to decrease the volume of the purge chamber; means operably connected to the piston valve to selectively produce movement thereof to decrease the volume of the purge chamber whenever ejection of water from the assembly is necessary; water catch means associated with the engine exhaust manifold to temporarily collect water which has been ejected from the purge chamber whereby exhaust heat subsequently boils the ejected water and releases it to the atmosphere thus avoiding undesirable ejection upon the ground.
