Regulating grill comprises a support housing (10) forming a passage for the flow of air, and displaceable eyelets (20) to regulate the flow of air. The housing and the eyelets are fixed together, where the eyelets are made from a material possessing a coefficient of dilation superior to the material of the support, so the eyelets deform to block more or less the passage as a function of the temperature of the air.
