Claims: I claim:

1. In geothermal deep well pump apparatus of the kind including pump means for pumping a first fluid always in liquid state for flow in cooperative energy exchanging relation with respect to a second fluid:

first, second, and third conduit means respectively for transmission of said first and second fluids and a third fluid and having first common wall means between said first and second conduit means and second common wall means between said second and third conduit means,

said first and second common wall means being disposed one within the other in substantially vertical concentric relation,

said first fluid being hotter than said second fluid and said second fluid being hotter than said third fluid, and

deflector means within said second conduit means for urging said second fluid into effecient proximate thermal energy exchange relation with said first common wall means and away from said second common wall means.

2. Apparatus as described in claim 1 wherein said deflector means comprises curved vane means pending from at least one of said first or second common wall means for imparting a component of rotational motion to said second fluid for increasing its proximity to said first common wall means thereby improving heat exchange between said first common wall means and said second fluid while diminishing heat exchange between said second common wall and said second fluid during passage of said second fluid through said second conduit means.

3. Apparatus as described in claim 2 wherein said second fluid constitutes a dual phase fluid including liquid drops and vapor for at least a portion of said passage through said conduit means.

4. Apparatus as described in claim 3 additionally including:

pump means coupled to said first conduit means for pumping said first fluid in the form of hot geothermal water therethrough,

motor means coupled to said pump means and responsive to said second fluid in the form of steam for driving said pump means, and

motor exhaust means for coupling said third fluid in the form of exhaust steam into said third conduit means.
