1. A flow proportioning device comprising:

  • a housing defining a chamber having inlet and outlet passages in substantially axial alignment;

    first and second flow proportioning members mounted in said chamber, each said member having an annular flange segment and an integral conical segment extending toward said outlet passage;

    notched panel means fixed in said outlet passage lying in a plane defined by the maximum relative movement of said flow proportioning members and receiving said conical segments therein; and

    means to engage said flange segments and oppositely rotate said flow proportioning members around said outlet passage axis thereby changing the relative positioning of said conical segments whereby the ratio of the non-predominant (volumetric-wise) phase of a two-phase system can be adjusted.
