ABSTRACT:
A variable flow restrictor valve is disclosed that is adapted to be inserted in a fluid line to provide first and second alternative flow paths therethrough in accordance with the pressure differential between inlet and outlet ends of the valve. The assembly is characterized by use of a moveable orifice tube which defines one of the alternative paths and an intermediate part of a valve housing defines a flow path which forms another alternative flow path having flow therethrough regulated by a stop disk and a valve disk both of which are fixed to the orifice tube on either side of the intermediate part to position the valve disk to either close or open the another alternative flow path in accordance with the aforesaid pressure differential.
