Abstract:
A gas regulator valve comprising means for lowering the pressure of a gas stream flowing therethrough to a specified pressure such that the mass flow rate of the gas stream is maintained at a substantially constant value wherein the pressure lowering means lowers the pressure of the gas stream as a function of temperature wherein the pressure lowering means comprises:a spring; a membrane; an inlet tube; an outlet tube; a body subdivided by the membrane into a first compartment in which the spring applies a force to the membrane and a second compartment into which the inlet and outlet tubes open wherein the membrane is subject to the pressure of the gas contained within the second compartment; a regulating mechanism comprising a valve and a seat wherein the regulating mechanism is mounted in the second compartment and wherein the regulating mechanism operates as a function of the position of the membrane as subjected to by the pressure of the gas within the second compartment; a bellows in contact with the spring; and a capsule supplying a fluid to the bellow.
