GAS PRESSURE REDUCER WITH DISK SPRING

摘要

The invention is directed to a two-stage gas pressure reducer 2. It comprises a body 1 with an actuating rod 26 for actuating a shut-off valve, a first chamber 36 crossed by the rod 26 and delimited by a gas tight membrane 42 connected to the rod 26 and to the body 1. A disk spring 12 is placed on the membrane 42 and exerts a biasing force on the rod 26 against the force exerted by the gas on the membrane 42 in the first chamber 36. This constructions of pressure and/or flow reducer or at least controller allows a space reduction, provides a reduction of parts and a simplification of assembly.
