Abstract

Regolatore a quattro livelli per impianti di condizionamento a fluido, comprendente un corpo contenente tre interruttori elettrici, ove detti interruttori includono rispettivi contatti fissi e rispettivi contatti mobili, ove ciascuno di essi include un puntale scorrevole per il comando dello spostamento di un rispettivo contatto mobile mediante l'azione di un rispettivo organo elastico a calotta, detti organi elastici essendo definibili fra una configurazione introversa di riposo ed una configurazione estroversa, fra il fluido e gli interruttori essendo presente una membrana elasticamente deformabile, in cui uno di detti organi elastici ed il puntale ad esso accoppiato sono forati e nel quale esiste un ulteriore quarto interruttore che include un puntale inserito nell'organo elastico e nel puntale forati, azionato da un rispettivo quarto organo elastico anch'esso a calotta.Four-level regulator for fluid conditioning systems, comprising a body containing three electrical switches, where said switches include respective fixed contacts and respective moving contacts, where each of them includes a sliding tip for controlling the movement of a respective moving contact by means of the action of a respective elastic cap member, said elastic members being definable between an introverted resting configuration and an extroverted configuration, between the fluid and the switches being an elastically deformable membrane, in which one of said elastic members and the tip coupled to it they are perforated and in which there is a further fourth switch which includes a toe inserted into the elastic member and into the perforated toe, operated by a respective fourth elastic member also with a cap.
