Abstract

Inventia se refera la un releu de presiune, destinat sesizarii a doua valori prestabilite ale presiunii unui fluid dintr-un punct de masura. Releul de presiune, conform inventiei, este format din niste capace de prindere în care sunt fixate niste membrane separate de un inel strabatut de un racord. Prin racordul respectiv patrunde fluid determinînd deplasarea membranelor, care, prin intermediul unor piese de contact si al unor piese de blocare, stabilesc circuitul unor microîntrerupatoare numai la atingerea unei valori prestabilite a presiunii fluidului. Aceasta valoare este fixata prin tensionarea unor resorturi împotriva carora actioneaza piesele de blocare.
