Abstract
A fluid flow control valve having a block defining a spool valve chamber and ports communicating with the chamber. A spool valve assembly for selectively controlling flow through the valve includes a spool body having an annular end provided with at least one axially outwardly opening notch. A spool end on the spool body defines a first frustoconical, axially outwardly narrowing outer surface concentrically within the annular end of the spool body, and a second, frustoconical, axially outwardly widening radially outer surface extending axially outwardly from the axial outer end of the first frustoconical surface and axially outwardly of the spool outer end.
