Title: Fuel distribution valve

Abstract

This patent describes a fuel flow distribution valve for dividing and metering fuel flow from a fuel source to nozzles for supplying fuel to an engine comprising valve body means having an inlet and outlets, intermediate liner means forming a longitudinal valve bore in the valve body means. The intermediate liner means has a reference surface thereon, a valve slidably supported in the valve bore slidable longitudinally therein and having a close tolerance diametral fit therewith. The valve has a positioning surface engageable with the reference surface and movable to a spaced apart position therefrom, spring means for biasing the valve in a first direction with respect to the liner means to engage the positioning surface and reference surface. The valve also has a means for directing inlet pressure against the valve in opposition to the spring means, pairs of in line-machined flow metering ports in the liner means and value with the ports in each pair being congruent by virtue of being machined simultaneously with a common tool in the liner means and the valve when the valve is in a fixed position in the bore with the positioning surface spaced a preselected longitudinal distance from the reference surfacemore » to define spaced pairs of congruent flow metering ports.« less
