Title:
MARINE FUEL PUMP AND COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO2000003137
Kind Code:
A3
Abstract:
An integrated fuel system component (10) comprising a fuel pump (52), a fuel filter (30) axially mounted directly below and around the lower portion of the fuel pump, and a spiral-wound fuel line (84) composed of a heat-conductive material mounted concentric to the upper portion of the fuel pump, minimizing the space required for installation. A fuel cooling system encloses the pump housing (70) and the fuel line in sealed chambers (66, 68) through which a liquid coolant is circulated to cool both the fuel pump and the fuel contained within the fuel line. A fuel pressure regulator (104) located between the fuel line and a fuel outlet (100) returns fuel to a fuel reservoir (24) located below the fuel filter, thereby providing a closed loop system. By combining the fuel pump, fuel filter, liquid cooling system, and pressure regulator into a single unit, the integrated unit minimizes vapor lock induced by heat, and optimally houses the fuel system components within a minimal volume of space.
