Fuel pressure regulator

A fuel pressure regulator comprising:

• a fuel inlet;
• a fuel outlet;
• a seating surface between said fuel inlet and said fuel outlet which is annular in shape;
• a valve member assembly comprising a poppet and also comprising a sealing member which is made of an elastomer material and which is annular in shape and includes a sealing member surface such that said sealing member is centered about a valve member assembly axis, said sealing member being supported by said poppet, and said valve member assembly being moveable between 1) a closed position in which said sealing member surface annularly engages said seating surface, thereby preventing fuel flow from said fuel inlet to said fuel outlet and 2) an open position in which at least a portion of said sealing member surface is spaced apart from said seating surface, thereby allowing fuel flow from said fuel inlet to said fuel outlet;
• and
• a spring which biases said valve member assembly toward said closed position, wherein said spring is centered about a spring axis which is laterally offset relative to said valve member assembly axis, thereby causing said valve member assembly to pivot, when moving between said closed position and said open position, about a pivot interface created by said seating surface contacting said sealing member surface.
