Abstract: In the case of a thermostatic valve for controlling the temperature of the coolant, particularly of a motor vehicle engine, it is provided that the working piston of the thermostatic valve is supported on a piston of a thermostatic working element which is aligned coaxially with respect to the working piston and serves as the supporting body. A restoring device is provided which is supported against the working piston and against the piston of the thermostatic working element.

Abstract: In an air ducting system for cooling air in an air duct in the front end of a motor vehicle, which is positioned with the air outlet at the underside of the front end in front of a capsule surrounding the engine compartment of the motor vehicle, a plurality of aerodynamically shaped hollow guide vanes internally traversed by a cooling medium which divide the air duct into a plurality of subducts is arranged as far as the air outlet opening at the underside of the front end in order to improve the airflow in the air duct and to cool the cooling medium.
