ABSTRACT:
A multiple outlet pitot pump with different output flows and/or pressures, comprising: a rotary casing; means for delivering a fluid to be pumped to the rotary casing; at least two discharge ducts generally coaxial with the rotary casing; at least two pitot tubes in and extending radially of the rotary casing, the pitot tubes respectively having adjacent their outer ends inlets facing in a direction opposite to the direction of rotation of the rotary casing, the pitot tubes respectively having radial passages and having adjacent their inner ends outlets respectively connecting the inner ends of the radial passages to the discharge ducts, and the pitot tubes further respectively having circumferentially rearwardly extending passages connecting the inlets to the outer ends of the radial passages; the inlets being different radial distances from the axis of the rotary casing to deliver fluid to the discharge ducts at different pressures; and the inlets being of different sizes to deliver fluid to the discharge ducts at different flow rates.
