The device is comprised of a first member (2) for regulating the fluid flow rate arranged to regulate the flow rate to a preselected value, and a second movable adjusting member (3) allowing to create a variable pressure loss, further comprising self-regulation means (4, 8, 12, 17, 5...) appropriate for compensating automatically any variations of the fluid pressure difference detected by the first regulation member in order to maintain constant the fluid flow rate through the device whatever the variation of pressure difference may be between the inlet and outlet. In such device, the driving energy of the fluid going through the adjusting members is used to regulate the fluid flow rate without requiring external energy, and the pressure difference between the inlet and outlet of the circuit. |
