Apparatus to regulate fluid flow
First Claim
Patent Images
1. Fluid flow operated apparatus operating automatically in response to fluid flow changes to adjust automatically a gain of a regulated fluid flow system, comprising:
- a self-adjusting fluid amplifier valve to receive fluid flow associated with an inlet of a regulator valve and to provide an adjusted fluid flow to a valve mechanism and to one side of a valve member of the regulator valve in response to the changes in fluid flow at an outlet of the regulator valve, the fluid amplifier valve having a flow pin at an amplifier orifice and the flow pin connected to the valve member of the regulator valve, wherein the changes in fluid flow at the outlet of the regulator valve cause the valve mechanism to regulate the adjusted fluid flow by responsively and simultaneously moving the valve member and the flow pin to vary automatically the gain of the regulated fluid flow system.

Abstract
Apparatus to regulate fluid flow are disclosed. The apparatus includes an example regulator valve and an example automatically-adjusting or self-adjusting amplifier valve to maintain fluid flow during low downstream demand fluid flow conditions, and to maintain the operational accuracy and stability of the regulator valve during higher downstream demand fluid flow conditions.
