| 摘要 |
The invention relates to a thermal servomotor which includes two operating elements particularly bellows boxes, which act oppositely on a valve actuating bridge. Each operating element has a temperature-dependent filling. Each operating element is connected to a relatively small container having a volume on the order of 0.2 cm3 by a capillary passage which has the effect of partially thermally insulating each operating element from the associated container. Each container contains the medium of the filling that determines the pressure and separate heating apparatus is associated with each of the two containers. |
