Abstract
A cooling radiator for the engine of a motor vehicle includes two movable masking members associated with the same fluid manifold of the radiator and actuated by a common actuator in response to the engine temperature. A first of these masking members closes the inlet of the manifold to prevent any flow in the radiator when the engine is cold. The second masking member controls an aperture in an intermediate bulkhead in the fluid manifold so that a variable fraction of the fluid flow in the radiator is diverted (when the manifold inlet is open) through the aperture, so that it does not pass through the tubes of the radiator. This radiator performs the function of a thermostat and also regulates the cooling function at the correct efficiency according to the power being produced by the engine.
