Fuel pressure regulator having offset head and orifice axes

Apparatus for regulating inline pressure of a liquid flowing through the apparatus, the apparatus including a valve and comprising:

• a) a valve seat having an axis, a flow orifice therethrough and a sealing surface;
• b) a valve head matable with said valve seat, said valve head having an axis, and a sealing surface;
• and
• c) a spring member disposed adjacent said valve seat,
• wherein said valve seat axis and said valve head axis are non-coaxial as a result of said spring member.

A method for preventing chaotic flow in an apparatus for regulating inline pressure of a liquid flowing through the apparatus, the apparatus including a valve seat having a flow orifice therethrough, said orifice having an orifice axis, and a valve head matable with said valve seat and having a valve head axis, comprising the steps of:

• a) forming a first mating surface on said valve head in a plane orthogonal to said valve head axis;
• and
• b) forming a second mating surface on said valve seat adjacent said first mating surface,
• wherein said orifice axis and said valve head axis are non-coaxial.
