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.
Claims6
In an internal combustion engine fuel system valve having a metal valve seat and a metal body, said valve body being moveable at relatively high rates of speed between a first open position at which the valve body is spaced from the valve seat and a second closed position at which the valve body is contacting the valve seat, the improvement comprising:
- said internal combustion engine valve body having a chamber, said chamber having a volume "X" of preselected magnitude;
- and
- a material having a volume "Y" less than the volume "X" of the valve body chamber, said internal combustion engine material being positioned within the valve body chamber and moveable within the chamber in response to deceleration of the valve body.
