A compact, gas pressure regulator makes use of a substantially disc-shaped member which is biased within the regulator by one or more spring members exerting forces on the disc-shaped member at multiple, discrete locations which are angularly separated from each other about the area of the first surface. Movement of the disc-shaped member toward or away from a high-pressure orifice maintains a regulated, lower pressure for delivery through an outlet in the regulator. A member for mounting a pressure gauge is secured to the housing of the pressure regulator without substantially increasing the overall length of the regulator.

[ What is claimed is:] [1.] A gas pressure regulator for mounting to a high-pressure gas cylinder used in hospitals, homecare and other healthcare institutions, the regulator comprising:means for securing the regulator to the cylinder;a housing having inner walls defining a chamber, the housing having therein means for metering the flow rate of the gas;an orifice in the housing for receiving gas at a source pressure;a gauge in pneumatic communication with the gas and connected to the housing;a nozzle secured to the housing and defining an outlet for delivering gas at a delivery pressure lower than the source pressure;a member movably mounted within the chamber, at least one seal between the member and the chamber to create a zone above atmospheric pressure, the member having a center and first and second opposite surfaces, the first surface having a seat opposing the orifice, the second surface and one of the inner walls of the chamber defining a head region in communication with the outlet; andspring means for exerting force on the member at multiple, discrete locations which are radially spaced from the center of the member and angularly separated from each other about the area of the first surface;the member and the seat being displaced a predetermined amount toward the orifice and against the forces exerted by the spring means in response to the pressure of gas received in the head region, thereby regulating the delivery pressure;the housing having an axial length extending substantially within the cross-sectional footprint of the gas cylinder when the regulator is mounted thereto, wherein should the cylinder fall against a planar surface, the housing and the gauge do not directly strike the planar surface.
