Abstract of the Invention A method and apparatus 10 for self-regulating the mass flow rate of a fluid comprises a housing 12 defining an upper chamber 14 and a lower chamber 16, a sealed and pressurized bellows 30 contained within the upper chamber 14, spring bias means 58 contained within the lower chamber 16 and a poppet 32 with a poppet head 40 for defining a fluid passageway 44. Supply fluid flows through inlet 56, lower chamber 16, fluid passageway 44 and into upper chamber 14. Once in upper chamber 14 the fluid is in heat exchange communication with a fluid in sealed bellows 30. When the mass flow rate of the fluid flowing through upper chamber 14 is effected by either in pressure or a change in temperature, a corresponding change takes place in the fluid in the bellows 30 thus repositioning the poppet head 40 accordingly to redefine the area of passageway 44. Fluid leaves the apparatus through exits 28.
