Disclosed is a cylindrical, single-component two-stage regulator for controlling a pressure and a flow rate of a gas. The regulator includes a housing for holding the two stages having an ingress adapted for connection to a source of gas at a high input pressure and an egress adapted for supplying gas at a lower output pressure than the high input pressure; a first stage for reducing the pressure of the gas from the high input pressure to a fixed intermediate pressure; and a second stage for reducing the pressure of the gas from the fixed intermediate pressure to the lower output pressure and regulating the flow rate of the gas out of the egress. One application of the present invention is for use in scuba (Self-Contained Under-water Breathing Apparatus) applications, where it replaces the traditional two-component user-adjustable regulator. The regulator may be made out of stainless steel, and is small enough to fit into a user's mouthpiece.

A fragmentation containment charging unit for gas cylinders that includes a steel housing having an interior compartment at least a portion of which defines a cooling chamber in which a compressor for use in charging the gas cylinders is mounted so as to be directly immersed so as to be in heat exchange with a cooing liquid within the cooling chamber and wherein the gas cylinders may also cooled during charging.

A regulator comprised of a housing having an ingress for connection to a source of gas at a first pressure and an egress adapted for supplying gas at a lower pressure than the first pressure. A fixed member, located within the housing, separates the ingress from the egress and has at least one opening extending therethrough. A throttling tube is located in the housing and extends through the opening in the fixed member to control the flow of gas from the ingress to the egress. The throttling tube has a first end juxtaposed with a compressible disk and a second end juxtaposed with a valve seat. An actuation lever responds to a pressure within the housing to move the throttling tube into and out of engagement with the valve seat. The throttling tube responds to a force provided by the disk when it is out of engagement with valve seat.
