The flexible hose portion has a first end in fluid communication with an outlet portal of the container and a second end to which the head is attached.
Claims16
An apparatus for withdrawing a cryogenic liquid from a container, comprising:
- a conduit having a flexible metallic hose portion and a metallic head;
- and,
- wherein the flexible hose portion has a first end in fluid communication with an outlet portal of the container and a second end to which the head is attached.
An apparatus for withdrawing a cryogenic liquid from a container, comprising:
- a conduit having a corrugated flexible metallic hose portion and a metallic head;
- and,
- wherein the flexible hose portion has a first end in fluid communication with an outlet portal of the container and a second end to which the head is attached, and the head follows a contour of the container when the contain is reoriented from a standard operating position to draw the liquid from the container independent of the orientation of the container.
A self-contained breathing apparatus having a supply of cryogenic liquid air, comprising:
- a tank within which a supply of cryogenic liquid is held;
- a regulator for controlling pressure within the tank;
- an outlet portal through which the cryogenic liquid is drawn;
- a heat exchanger in fluid communication with the outlet portal and an interior of the tank;
- a flexible metallic conduit disposed within the tank and in fluid communication with the interior of the tank, the outlet portal and the heat exchanger;
- and,
- a mask for breathing air having been created by the liquid air traveling from the tank through the heat exchanger.
