Abstract:
1. A fluid regulator, comprising: a valve body having a main passageway defining an orifice to fluidly couple an inlet and an outlet, wherein the main passageway defines an inlet volume boundary between the inlet and the orifice and an outlet volume boundary between the orifice and the outlet, and a portion of the outlet volume boundary being defined by at least a portion of an inner wall of the valve body adjacent the orifice; a valve plug disposed within the passageway such that the inner wall substantially surrounds an outer surface of the valve plug to substantially prevent fluid flow between the inner wall and the outer surface of the valve plug and toward a sensing chamber of the fluid regulator; a secondary fluid passage formed in a portion of a perimeter of the inner wall of the valve body to increase fluid flow toward the sensing chamber of the fluid regulator when a fluid flows across the orifice; and a stem guide, the stem guide being spaced away from the inner wall.
