Mannhardt, W G

This patent describes an improvement in a fuel metering valve assembly. It comprises: housing means defining a chamber adapted to contain fuel under pressure, valve seat means on one wall of the chamber defining a valve seat surface and outlet passage bores extending through the seat means symmetrically disposed about a central axis, valve poppet means having a poppet surface mounted in the chamber for reciprocatory movement along the axis between a valve-open position wherein the head surface is spaced from the seat surface to accommodate flow from the chamber into the bores and a valve-closed position wherein the valve poppet surface is engaged with the valve seat surface in overlying relationship with the valve seat bores to block flow from the chamber into the bores, and means for cyclically driving the valve poppet means between the open and closed positions.
