ABSTRACT:
An automatic fluid flow regulator particularly adapted to maintain equilibrium within a cryogenic fluid system. The regulator includes a housing that has an input port and first and second output ports. A housing of the regulator contains a spool body having longitudinally extending expanding fluid channels provided on its outer periphery. The spool body cooperates with spaced flow restriction shoulders on which it is slidably disposed to bias the spool body by means of pressure differences exerted on the ends of the spool body by disturbances in the branches of the system to a position in which more fluid is supplied to one branch while less fluid is supplied to the other branch and the fluid system is brought into equilibrium.
