■ · Cam disks are each equipped with an expansion thermometer - \. '■ (Bimetal steam pressure thermometer or the like.) Connected in the flow and return of the water. If both thermometers show the same temperature, the disks with their parts of larger diameter are facing each other _; so that the rollers 8 do not find a slot into which they can collapse »Since the cam disks of the thermometers are steepened in the same sense by the thermometers as the absolute temperature rises, there is no adjustment of the disks against each other even with a steady increase in the temperature in the gate and return on, only when a different temperature is displayed in the flow than in the return, '/, - earth the discs according to the temperature difference of the thermometer adjusted against each other.
