Abstract
Abstract A fluidic pressure regulator comprising a hollow housing having a diaphragm therein which forms a chamber through which fluid is passed. Means are provided for applying a load to the diaphragm in an opposite direction to the force exerted by the pressurized fluid on the diaphragm, which load varies in response to changes in the pressure of the fluid passing into the chamber.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
156 words
A pressure regulator comprising: a first hollow housing member having a first threaded portion; a second hollow housing member having a second threaded portion; said first threaded portion being connected to said second threaded portion; a chamber formed by said housing members; said first hollow housing member having an inlet passage to said chamber; a valve seat disposed in said inlet passage; said first hollow housing member having an outlet passage from said chamber; a disc plate disposed in said chamber; clamping means for loading said disc plate; said inlet passage having a ball valve disposed therein; connecting means connecting said ball valve to said disc plate; and said clamping means being arranged to apply an edge moment to said disc plate for preloading said disc plate so that said disc plate is responsive to the pressure in said chamber and is operative to move said ball valve in response to the pressure in said chamber.
