An annular elastomer is provided in a housing orifice that does not require a large force for deformation. This makes possible a solenoid-type actuator that provides a large displacement of the elastomer, thus allowing higher and lower rates of gas flow through a gas line.

Solid state regulator for natural gas

A solid state apparatus for regulating the flow of fluids in general, and natural gas, in particular, is provided. The solid state apparatus includes an actuator made of electrostrictive, magnetostrictive or piezoelectric material. The actuator displaces upon application of an electric field to vary the compression on an elastomer having an orifice, thereby varying the amount of elastomeric material extruded into the orifice. Fluid flow through the regulator is thereby controlled. A system for regulating the flow of gas integrates the regulator with a sensor to detect a gas characteristic, such as gas partial pressure, and send control signals to control the operation of the regulator. The solid-state gas regulator is capable of low cost production and operation and suitable for electronic feedback control.
