ABSTRACT:
A shutter (1; 10) for regulating the fluid flow in an absorber pipe (D) of a solar-thermal power plant comprises a shutter body (2) with a central shutter opening (3) for the fluid (F) and a movable throttle element (4; 12) at least partly closing the shutter opening (3; 11). The throttle element (4) is connected to a motion element (6) that is in thermal contact with the fluid (F) and changes its shape as a function of the fluid temperature so that in case of an increased temperature of the fluid (F), the opening cross section of the shutter opening (3; 11) is enlarged, whereby the mass flow of the fluid (F) increases and the temperature thereof drops.
