Abstract

Soupape automatique de sûreté comportant un organe indiquant qu'elle s'est écartée de son siège. Cet organe indicateur est une lame de ressort dont une extrémité est solidaire de la soupape et dont l'autre extrémité est maintenue par un déclic solidaire du logement de cette soupape. Dès que cette dernière s'écarte de son siège, le déclic libère la lame de ressort qui se détend et indique ainsi que la soupape a fonctionné. Application notamment aux soupapes de sûreté des transformateurs-régulateurs.
