Besonders vorteilhaft ist die Ausbildung des Regelventils als quer durch den Luftführungskanal geführter Bolzen. Dieses Regelventil ist einfach aufgebaut und leicht bedienbar. Bevorzugte Betriebsstellungen dieses Regelventils können auf einfache Weise durch Rasten gekennzeichnet sein. Im Zusammenwirken mit den leicht auswechselbaren Formstücken an der Kanalmündung kann es zweckmäßig sein, die verschiedenen Formstücke mit den verschiedenen Regelstellungen des Regelventils zugeordneten, identischen Marken zu versehen.The measures listed in the subclaims are advantageous developments and improvements the specified hand tool possible. The design of the control valve is particularly advantageous as a bolt guided across the air duct. This control valve is simple and easy to use. Preferred operating positions of this control valve can be easily identified by notches. In cooperation with the easily interchangeable Fittings at the channel mouth, it may be useful to combine the various fittings with the to provide identical brands assigned to different control positions of the control valve.
