Pneumatic component for controlled gas flow regulation at outlet of pressure regulator, e.g. in gas mixer, is based on inlet chamber closed by movable shutter and outlet chamber

摘要

A pneumatic component for controlled gas flow regulation comprises inlet chamber(s) (101), closed by a movable shutter (112); and outlet chamber(s) (103), open at one end via a constriction (120) and closed at the lower end by a cover (104). An opening (102) connects the inlet chamber outlet to outlet chamber inlet. First and second side openings (110, 121) allow entry of gas to the inlet chamber and evacuation of gas via the outlet chamber. A pneumatic component for controlled gas flow regulation comprises inlet chamber(s) (101) within a hollow body (100), closed by a movable shutter (112) sealed against a seat (111) at the chamber outlet; and outlet chamber(s) (103), open at one end via a constriction (120) and closed at the lower end by a cover (104) sealed against the body. An opening (102) connects the inlet chamber outlet to outlet chamber inlet; and side opening(s) (110), pierced in the body and connecting with the inlet chamber, allow(s) entry of gas across the inlet chamber into the component interior. Second side opening(s) (121), pierced in the body and connecting with the outlet chamber, allow(s) evacuation of gas across the outlet chamber to the exterior of the device. An independent claim is included for a multi-component gas mixer, containing a component as above to regulate the gas flow. The cover (104) closing the outlet chamber (103).
