Abstract
A fuel pressure regulator includes a fuel inlet; a fuel outlet; a seating surface; and a valve member assembly. The valve member assembly includes a poppet and also includes a sealing member which is centered about a valve member assembly axis, is annular in shape, and includes a sealing member surface. The valve member assembly is moveable between 1) a closed position in which the sealing member surface annularly engages the seating surface, thereby preventing fuel flow from the fuel inlet to the fuel outlet and 2) an open position in which at least a portion of the sealing member surface is spaced apart from the seating surface, thereby allowing fuel flow from the fuel inlet to the fuel outlet. A spring biases the valve member assembly toward the closed position and is centered about a spring axis which is laterally offset relative to the valve member assembly axis.
