Abstract

Un bloccaggio a leva di impegnamento per viratore di rotore in una turbina a vapore comprende un bloccaggio selezionabile.che è. disposto in modo da trattenere la leva nella sua posizione impegnata e una disposizíone circuitale di comando per attivare il bloccaggio selezionabile. Con una prima forma d'esecuzione il bloccaggio, selezionabile comprende un elettromagnete. D'altra parte, con una seconda forma d'esecuzione, il bloccaggio selezionabile comprende una disposizione a pistone-spina che viene attivata da un solenoide in modo da estendersi in un foro formato nella leva e viene spinta verso una posizione ritratta via dal foro da una molla che è disposta attorno alla spina tra il pistone e il solenoide.
