Abstract
A flow rate adapter includes an enclosure defining an interior, a first partition separating the interior into first and second chambers, a second partition separating the interior into third and fourth chambers, and a flexible diaphragm separating the second and third chambers. Each chamber is fluidly isolated from one another. The second and third chambers are positioned between the first and fourth chambers with the second chamber being positioned adjacent to the first chamber and the third chamber being positioned adjacent to the fourth chamber. The second and third chambers are positioned adjacent to one another. The flow rate adapter includes a gate coupled with the flexible diaphragm. A temperature gradient between working fluid flowing through the first and fourth chambers causes the flexible diaphragm to flex, which moves the gate within the fourth chamber to control the flow rate of the working fluid.
