1. A fuel injector assembly comprising:
a member having a first center along a longitudinal axis, the member comprising:
a curved surface having a radius of curvature, the radius of curvature of the curved surface being greater than a width of the member, and
a flat surface axially opposed to the curved surface; and
a seat having a second center disposed on the longitudinal axis, the seat being positioned distal from the flat surface defining a flow path in an open position of the fuel injector assembly, and in confronting relation to the flat surface such that the second center is concentric to the first center forming a sealing interface in a closed position of the fuel injector assembly.
