Controlled gas flow regulator and controller

摘要

A controller and regulator of gas flow consists of a chamber containing nozzles (16, 17), piston operated stop valves (20, 21) and a reservoir. The chamber has a high pressure entry space (1) within which an internal wall (22) supports two stop valve pistons (20, 21). The pistons are actuated by conduits (23, 24) and are fitted with return springs (18) (19). Nozzles of varying capacities (16, 17) are screwed into an internal wall (15) and these feed a reservoir (10) and outlet pipe (11). Total flow is regulated by microprocessor selection of combinations of nozzles opened or shut.
