Regulator valve assembly and components thereof

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 anda 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. 提供调节阀组件用于与高压流体系统结合使用。调节阀组件包括阀销和阀座，阀销具有带锥形表面的接合部分，以及阀座，阀座具有阀销接收孔，阀销接收孔限定阀座上的锥形表面，以与阀销的接合部分密封配合。阀销和阀座中的至少个包括不对称表面特征，其尺寸和形状设计成使得当阀销移动远离就位构造的位置时并且流体流过在阀销的接合部分和阀座之间产生的环形空间时，不平衡的流体动力由流体与不对称
