Abstract

Self-regulating valve. The valve includes a static pressure chamber with an elastically collapsible tube supported within the static pressure chamber. A flow restrictor is in fluid communication with an inlet into the static pressure chamber for flow through the collapsible tube. Piping connects a source of pressurized liquid, both to the flow restrictor and to an opening into the static pressure chamber, whereby flow rate through the valve remains substantially constant with variations in pressure of the pressurized liquid. In a preferred embodiment, the flow restrictor is a needle valve.
