PROVISIONAL SPECIFICATION.
Improvements in Regulators for High Pressure Gas.
ALFRED SUITER 2, Como Road Perry Vale Forest Hill Kent Mechanical
Engineer do hereby declare the nature of this invention to be as follows:-
High pressure gas regulators, as ordinarily constructed, require considerable
power to close the valve against the pressure of the gas, the necessary power being
derived by levers, screws, &c. and an accordion shaped bellows, the shape of such
bellows necessitating its being made of a material such as rubber, leather, &c.,
which is perishable, and is injuriously acted upon by some gases; and the pressure
of the gas given off varies considerably, according to the pressure of gas in the
storage cylinder.
The object of this invention is to so construct the regulator that the valve can be
acted upon direct by a simple diaphragm, such diaphragm owing to its small range
can be constructed of metal, or any other suitable substance not acted upon by gas,
such as hydrogen; and to simplify the regulator by dispensing with levers, screws,
spiral springs, weights &c., and the gas given off shall be of one uniform pressure,
no matter what the pressure of gas in the storage cylinder may be.
In carrying out my invention, I employ an equilibrium valve or valves, but
instead of the ordinary equilibrium valve for low pressure gas, steam &c., where
both valves are on one spindle, one valve being smaller in diameter to allow of its
passing through the seating of the other valve; I make both my valves of exactly
the same diameter, one valve and seating being loose, or separate, and capable of
being fixed after the centre spindle is in place; or in cases where an exactly uniform
pressure of gas given off is not required, 1 employ only one valve, and make it so
minute in diameter, that it requires very little power to overcome the pressure of
the gas in the storage cylinder. In both cases I make the valves to open inwards,
and I connect the centre valve spindle direct on to a disc or diaphragm, the
springing of which by the pressure of the gas given off closing the valve, without
the intervention of any levers, screws, &c. 1 make this disc or diaphragm of a
suitable thickness, the springing of which dispenses with the usual spiral spring, or
weight.

COMPLETE SPECIFICATION.
Improvements in Regulators for High Pressure Gas.
ALFRED SUITER 2, Como Road Forest Hill Kent Mechanical Engineer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
High pressure gas regulators as ordinarily constructed require considerable
power to close the valve against the pressure of the gas, the necessary power being
derived by levers screws &c., and an accordion shaped bellows, the shape of such
bellows necessitating its being made of a material such as rubber, leather &c.
which is perishable and is injuriously acted upon by some gases; and the pressure
of the gas given off varies considerably according to the pressure of gas in the
storage cylinder.
The object of this invention is to so construct the regulator that the valve can be
acted upon direct by a simple diaphragm, such diaphragm owing to its small range

such as hydrogen, and to simplify the regulator by dispensing with levers, screws,
spiral springs, weights &c., and the gas given off shall be of one uniform pressure
no matter what the pressure of gas in the storage cylinder may be.
In carrying out my invention 1 employ an equilibrium valve, the balance valve
and seating being loose or separate and capable of being fixed after the centro
spindle is in place. In cases where an exactly uniform pressure of gas given off is
not required, I employ only one valve, and inake it so minute in diameter that it
requires very little power to overcome the pressure of the gas in the storage
cylinder. I make the valves to open inwards and in both cases connect the centre
valve spindle direct on to a dise or diaphragm the springing of which by the pressure
of the gas given off, closing the valve without the intervention of any levers,
screws &c. I make this disc or diaphragm of a suitable thickness, the springing of
which dispenses with the usual spiral spring or weight.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which Figures 1 and 2 are
elevations (part in section) of two high pressure gas regulators constructed
according to my invention.
Similar letter in both figures represent similar parts. A is neck for connecting
to compressed gas vessel by socket B. it is passage for high pressure gas, & is valve
connected direct on to diaphragm, d, by valve spindle c, and is low pressure gas
outlet.
..
The operation of the instrument is as follows: Upon high pressure gas being
admitted to passage a, it finds its way by valve b, to chamber underside of
diaphragm d, the outlet being closed by flexible tube or stop cock, the pressure
rises until the diaphragm d, springs or buckles, so closing the valve b, and prever ing
more gas entering; the pressure of the gas in chamber on the undersi
diaphragm d, and given off by outlet e, being regulated by the clamping nuts
heing so adjusted that the diaphragm d, must spring or buckle more or less fore
closing valve b.
of
In cases where an exactly uniform pressure of gas is required to be given off at
the outlet,
the valve Fig. 1 is added to balance the valve , so that there shall
not be a varying force tending to close the valve (according to pressure in the
vessel) against the antagonistic springing of the diaphragm, so that the antagonistic
springing of the diaphragm is constant, and closing the valve 6 when the pressure
has risen to the predetermined extent in chamber d' no matter what the pressure of
gas in the vessel may be.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what 1
claim is
1. In regulators or governors for high pressure gas, the use of a valve opening
inwards and connected direct on to n diaphragm without levers screws spiral springs
or weights substantially as hereinbefore described.
2. In regulators or governors for high pressure gas, the use of an equilibrium
valve substantially as hereinbefore described and represented in accompanying
drawing.
