Definitions
- the operation of the system is such that when one of the valves is open the other shuts, so that air is directed to the molecular sieve tank 26 in the first in ⁇ stance.
- the oxygen is passed through a check valve 30 into a storage tank 32, which holds the oxygen therein for delivery.
- the output port 34 allows for delivery of oxygen from the system.
- the nature of the molecular sieve tank is that after passing gas therethrough at a typical input pressure of, for example 15 PSI, or a time period typically somewhere between 15 and 25 seconds, the sieve material will no longer adsorb any further nitro ⁇ gen and the nitrogen will pass through the filter, thereby decreasing the concentration of oxygen.
- a secondary filter 66 may be coupled to the output of the pump 62, and contains a filter element 68 for futher air purification, particularly if pump 62 is a carbon pump,
- the output of the secondary filter 66 passes through the flow switch 58 to a molecular sieve tank 70, which may be of conventional construction including a molecular sieve material 72 operating as described hereinabove with respect to prior art systems.
- the output of the molecular sieve tank 70 is coupled through a one way or check valve 74 to an oxygen storage or ballast tank 76,
- the output of the oxygen ballast tank is provided via an output port 78 through a pressure regulator 80 of conventional design to a flow adjustment mechanism 82, which includes a flow gauge 84 for measuring the through-flow.
- the output of the flow adjustment mechanism 82 is coupled to a further-bacterial filter 86, containing a suitable bacterial filtering ate- rial 88, and thence via an output port 90, for' use external to the system.
- the flow switch " 58 consists of a body 90 having a plurality of inlet and outlet ports, 92, 94, 96 and 98.
- the central communica ⁇ ting bore 100 is traversed by means of a piston 102 having two positions, position I shown in Figure 3 and indicated by solid lines in Figure 2, and position II shown in Figure 4 and indicated by dotted lines in Figure 2.
- a further orifice or port 104 shown in Figures 2, 3 and 4 communicates duct 93A with oxygen tank 76 via air flow valve 99 which is acti- vated by pressure switch 93, as previously described.
