ABSTRACT:
Fuel rail assemblies for supplying fuel to injectors of internal combustion engines include mounting structure to integrally mount a fuel pressure regulator. An annular chamber, in fluid communication with the fuel passageway of the fuel rail, is defined between a mounting section of the fuel rail and a lower housing portion of the regulator. Apertures in the lower fuel rail housing portion thus allow fuel to flow into the regulating chamber of the fuel regulator from the defined annular chamber. In some preferred embodiments, the integral mounting structure includes a mounting cup having an upper cup section and a lower tail section for receiving a fuel pressure regulator and thus regulating upstream fuel pressure within the fuel rails. Fluid communication is established between the fuel rail and the cup section of the mounting cup while fluid isolation between the cup and tail sections of the mounting cup is established by suitable seal structures. Thus, fuel enters the cup section from the fuel rail and is forced to flow through the fuel pressure regulator by virtue of the fluid isolation established between the cup and tail sections.
