ABSTRACT:
A shutter mechanism for an engine radiator comprising a series of rigid pus tubes having elastomeric sleeves secured thereto. Introduction of pressurized fluid (e.g. compress air or engine coolant) into the porous tubes pressurizes the spaces between the tubes and sleeves, thereby causing the sleeves to balloon outwardly to fully or partly close the air supply passage leading to the radiator. Depressurization of the tube interior spaces allows the elastomeric sleeves to contract onto the tubes, thereby opening the radiator air passage system.
