2. PORTABLE OXYGEN CYLINDER ASSEMBLY - DESCRIPTION

SUBTASK 35-35-59-870-003-A01
A. General Description
(1) The portable oxygen cylinder assembly is made up of a cylinder, a regulator
assembly, and up to two oxygen masks.

SUBTASK 35-35-59-870-004-A01
B. Cylinder
(1) The cylinder is a U.S. Department of Transportation (DOT) and Transport Canada
(TC) rated pressure vessel that holds oxygen gas at a nominal working pressure of
1800 to 1850 psig (12,4 - 12,8 MPa). The cylinder is made of seamless aluminum
that is wrapped with carbon fiber. Refer to chapter INSPECTION/CHECK for
information on the cylinder service life and the hydrostatic test frequency.

SUBTASK 35-35-59-870-005-A01
C. Oxygen Regulator Assembly
(1) The single inlet regulator assembly lowers inlet pressure from the cylinder to the
outlet assembly. The regulator assembly has an ON/OFF valve, a pressure gauge,
a relief valve, a safety outlet, a charging valve, and an outlet fitting attached. The
807801-01 and 807801-02 regulator assemblies have a plug installed in one port.

3. PORTABLE OXYGEN CYLINDER ASSEMBLY - OPERATION

SUBTASK 35-35-59-870-006-A01
A. Regulator Assembly
(1) The regulator reduces high-pressure oxygen stored in the cylinder to a lower
pressure suitable for use with constant flow-type mask assemblies.
(2) (Refer to Fig. 3) for cross sectioned views of a regulator shown in the closed
position. Turning the selector knob (6) counterclockwise provides a flow of 2
liters per minute. When a flow of 2 liters per minute is indicated in the window, a
mechanical detent is felt. The mechanical detent feature is accomplished using
two springs (10) and nylon balls (11). The selector has two indentations (12) to
capture the nylon balls (11).When the selector knob (6) is turned counterclockwise
until a flow of 4 lpm is indicated in the window, the knob comes to a mechanical
stop, and the flow increases to 4 lpm.
(3) When the ON/OFF handle (1) is turned to the ON position and the selector knob
(6) is set to a flow setting, the valve stem (2) and valve head assembly (3) move off
of the seat, allowing oxygen to enter the high pressure valve of the regulator.
(4) As pressure builds beneath the piston assembly (4) the force begins to compress
the regulator spring (5) allowing the piston assembly (4) to move up. The bias
spring (7) moves up with the piston assembly (4) to regulate the flow of gas through
orifices in the selector plate (9). Low pressure oxygen gas is now available at the
low pressure outlet fitting (8) of the regulator. When the knob is moved further
counterclockwise to the mechanical stop, the selector plate (9) turns to a new
position. The new position changes the orifice in the flow path and also changes
the flow rate out of the outlet fitting (8). To close the valve, the ON/OFF handle (1)
is turned clockwise (finger tight). This moves the valve stem (2) and valve head
assembly (3) against the surface of the seat and stops the flow of oxygen.
