A mini-regulator valve assembly for providing a continuous supply of fluid at a predetermined pressure from a source of high pressure fluid. The valve has a first member adapted to join with the fluid source and a second member disposed for movement relative to the first member, one of the members forming a valve seal and the other forming a sealing edge cooperating therewith. The valve is further provided with a first biasing spring, a second biasing spring and an actuator. The first biasing spring biasing the second valve member against the first valve member and the second biasing spring acting on the actuator such that when the second biasing spring moved inward, the actuator acts on the second valve member moving the valve seat and edge away from each other thereby opening the valve, the first spring in combination with the pressure of the fluid passing through the valve ending close to the valve as the pressure builds up and thereby obtaining a regulating affect.

A regulating valve for use in a gas cylinder having an opening formed therein comprising: (a) a first valve member adapted to be retained in the opening in the cylinder; (b) a second valve member disposed for movement with respect to said first valve member, one of said first and second valve members forming a valve seat and the other forming a sealing edge cooperating with said seat thereby forming an outlet valve from the cylinder; (c) first biasing means biasing said second valve member against said first valve member so as to bring said sealing edge into contact with said seat and close said valve; (d) an actuator for acting on said second valve member, said actuator having an outlet passage, said actuator supported for limited axial motion; (e) means associated with said actuator forming an inner chamber in communication with said outlet valve, said inner chamber having an outer surface of area greater than the area of said outlet passage, and an outer chamber; (f) at least one port formed in said actuator establishing communication between said inner chamber and said outlet passage; (g) an axially adjustable support surface; and (h) second biasing means disposed in said outer chamber between said support surface and said actuator, whereby axially inward movement of said actuator will cause it to move said seat and edge apart to permit a flow of gas into said inner chamber and through said ports, said gas thereupon acting over said outlet passage along with the biasing force of said second biasing means and aided by the biasing force of said first biasing means to tend to close the valve comprising said valve seat and said edge as pressure builds up to the desired value to thereby obtain a regulating effect.
