 sollen als mit reinem Abdampfbetrieb und bei denen ein dem Abdampfdruck unterworfener Druckregler   die Umstellung   von Frischdampf- auf Abdampfbetrieb und umgekehrt bewirkt, dadurch gekennzeichnet, dass ausser dem bekannten   Druckregler noch   ein Druckregler (8) angeordnet ist, dessen Kolben oder analoges Organ einerseits dem Drucke des zuströmenden Abdampfes, andererseits dem Drucke des gesamten Dampfgemisches, welches die Turbine speist, unterworfen ist und bewirkt, dass in jeder Stellung des Abdampfventils bei Zunahme der verfügbaren Abdampfmenge eine Verringerung des Frischdampfzuflusses nur solange erfolgt, als der Abdampfen noch nicht voll belastet ist.

 are intended as with pure exhaust steam operation and in which a pressure regulator subjected to the exhaust steam pressure effects the changeover from live steam to exhaust steam operation and vice versa, characterized in that in addition to the known pressure regulator, a pressure regulator (8) is also arranged, the piston or analogous element of which on the one hand corresponds to the pressure of the inflowing exhaust steam, on the other hand, is subject to the pressure of the entire steam mixture which feeds the turbine and has the effect that in every position of the exhaust valve, when the amount of exhaust steam available increases, the live steam flow is only reduced as long as the steam is not yet fully loaded.

Claims (1)

2. Steuerung nach Anspruch 1, dadurch gekennzeichnet, dass der Expansionsraum der Nieder- druckturbine in zwei getrennte Teile 72. 1. geteilt ist, wobei eine Seite des die Regelung bc- einflussenden Kolbens von dem Drucke beeinflusst wird, der hinter dem ersten Rad (14) der Nieder- druckturbine herrscht (Fig. 2 und 3). 2. Control according to claim 1, characterized in that the expansion space of the low-pressure turbine is divided into two separate parts 72.1, whereby one side of the piston influencing the control bc- is influenced by the pressure behind the first wheel ( 14) the low pressure turbine prevails (Fig. 2 and 3).
