ABSTRACT:
A pressure regulator for liquid pumping systems, and particularly fuel supply systems for use in vehicles, is disclosed. The regulator is designed with an inlet from the fuel pump, an outlet to the engine fuel inlet, and a drain outlet for draining fuel, in excess of that required by the engine, back to the fuel tank. During engine operation, fuel flow is continuous from the tank to the fuel pump, and from the fuel pump to the regulator. In most cases, fuel is continuously flowing from the regulator back to the fuel tank. Constant fuel flow through the regulator replenishes, in the regulator, the fuel drawn by the engine. A consistent fuel pressure is presented to the engine fuel inlet. The regulator and its systems are disclosed, as are methods of use of the regulator and the systems.
