Abstract
A regulator valve assembly is provided for use in connection with high pressure fluid systems. The regulator valve assembly includes a valve pin having an engagement portion with a tapered surface and a valve seat having a valve pin receiving aperture defining a tapered surface on the valve seat to sealingly mate with the engagement portion of the valve pin. At least one of the valve pin and the valve seat includes an asymmetrical surface feature sized and shaped such that, when the valve pin is displaced away from the seated configuration and fluid flows through an annular space created between the engagement portion of the valve pin and the valve seat, unbalanced hydrodynamic forces arise from an interaction of the fluid with the asymmetrical surface feature. Systems incorporating the regulator valve assembly are also provided.
