Abstract
A device for regulating the flow of air through a heat exchanger has a multiplicity of shutters pivotally mounted on parallel axes and actuated by control means that include an actuating plate which carries a number of cam tracks of selected shapes. Each cam track is arranged to engage a corresponding cam which is fixed to a respective one of the shutters for rotating the latter when the actuating plate is moved. The invention is especially applicable to motor vehicle engine cooling radiators.
