Patent ID: 8336574

Claim:
A fluid regulating device, comprising: a valve comprising an inlet, an outlet, and a valve port disposed between the inlet and the outlet for allowing fluid to flow through the valve; an actuator coupled to the valve and comprising a control assembly, the control assembly comprising a control element and a diaphragm operably connected to the control element, the control element extending into the valve and adapted to be displaced relative to the valve port for controlling the flow of a fluid between the inlet and the outlet; a sense tube comprising a sensing portion and a mounting portion, the sensing portion comprising a tubular wall extending along a central longitudinal axis and an open end defined by the tubular wall and disposed proximate to the outlet of the valve and the mounting portion disposed proximate to the diaphragm of the actuator, the open end of the sensing portion comprising a complete cross-section through the tubular wall and disposed in a first plane that intersects the central longitudinal axis; and an elongated slot defined by the tubular wall of the sensing portion of the sense tube and extending from the open end to the mounting portion, the elongated slot disposed in a second plane that intersects the first plane such that the sensing portion is adapted to average the pressure at the outlet of the valve such that the sense tube communicates the averaged pressure to the diaphragm.
