A gas generator assembly, which is especially suited to both transportable and on-board oxygen generators, with at least one adsorbent and a buffer tank to store product gas separated from a feed gas mixture. In order to make the assembly squat and compact, the buffer tank may be of an annular or quadruple U shaped configuration. Such a buffer tank configuration may also provide the assembly with improved structural and protective attributes.

Gas generator assembly

A self-contained oxygen generator containing a PSA unit and a flowmeter in the outlet line. The flowmeter provides a signal which represents the flow rate of the oxygen in the outlet line. A leakage circuit with a calibrated orifice and a solenoid valve are also located on the outlet line. In response to a signal from the flowmeter, the solenoid can be actuated so as to provide a calibrated leakage at the outlet of the PSA. This calibrated leakage is useful when overall oxygen usage is too low.
