ABSTRACT:
A pulse dampener for fuel systems having a rotary fuel pump and a fuel flow passage. The pulse dampener includes a hollow torus-shaped body with a fluid disposed within the body and the hollow body defining two flat surfaces disposed in spaced parallel relation with respect to one another and perpendicular to the flow of fuel through the fuel system. The pulse dampener further includes a pair of sides disposed perpendicular to and interconnecting the spaced flat surfaces to define the torus shaped pulse dampener to dampen pressure pulses within the fuel.
