Abstract

A fuel system valve has a metal valve seat and a metal valve body. The metal valve body has a chamber which contains material which is moveable through the chamber in response to deceleration of the valve body. The forces of the material within the chamber on the valve body during rapid deceleration of the valve body counteract the forces subjected on the valve body in response to contact with the valve seat.
