Abstract: A discharge water system for the bilge of a boat includes a primary bilge discharge system and a supplemental bilge filtration system. The primary discharge system includes a pump operable when the fluid in the bilge collects above a predetermined level in the boat to discharge bilge water overboard. The supplemental system includes a filter assembly with filter media for removing hydrocarbons in bilge water passing through the media; and a pump operable when the water in the bilge collects to a selected level below the operating level “L” of the primary pump to pump bilge water to the filter assembly and then to discharge the essentially hydrocarbon-free bilge water overboard. The filter assembly includes primary secondary filter cartridge, both of which include hydrocarbon-absorbing media, and are connected in series. A pressure sensor and remote indicating device provide an indication of the primary filter cartridge becoming spent.

Abstract: An improved valve, responsive to the loss of coolant under pressure in a diesel engine or the like, to open and allow fluid flow downstream with a consequent loss in fluid pressure, which is recognized by a pressure sensitive fuel valve supplying fuel flow to the engine. The coolant loss valve includes a three-part housing having the periphery of an elastomeric rolling diaphragm trapped between two housing parts and forming a coolant chamber. A spring-loaded piston and pin assembly transmit diaphragm movement, the pin forming a valve controlling fluid flow through a die cast aluminum head structure which is the third part of the housing. A stainless steel pin is used for corrosion resistance and is supported for axial movement in a dual quad ring seal and sleeve structure.

Abstract: A filter cartridge uses two annular concentric filter media with a first contaminant outlet upstream from both media and a plurality of second contaminant outlets between the two filter media. A mating portion on the filter cartridge mates with a wall of a collection bowl having dual contaminant collection zones.

Abstract: A fuel filter assembly in which a filter cartridge, threadedly supported from a mounting unit, engages and supports a contaminant collection bowl having a plurality of collection zones respectively upstream and downstream of fuel treatment means within the cartridge. In general, a dual media filter element includes a flow passage axially thereof with means at one end for carrying the filter element from a support head, and means on the other for supporting a contaminant collection bowl beneath. A primer pump disposed axially of the filter element moves between advanced and retracted position therealong.
