Improvements in or relating to Regulating Valves or Devices for
the Supply of Liquids or Fluids under Pressure.
A communication from HABING HARINGS DIKEMA, Engineer, of Brussels, in the
Kingdom of Belgium.
1, ALFRED JULIUS BOULT, 111 Hatton Garden in the County of Middlesex
Chartered Patent Agent, 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 :-
The present invention relates to an apparatus forming a regulating valve or
device which enables liquids of any kind, whether saturated with gases under high
pressure or not to be drawn off under the reduced pressure and the exact pressure,
under which the bottles or other vessels are filled to be maintained and controlled.
It is possible to saturate a liquid, such as water for instance with a gas, such as
carbonic acid under high pressure say 8 to 10 atmospheres and to transfer the
liquid directly into bottles or other receptacles but at a considerably reduced
pressure say of 2 atmospheres.
It will be seen that for the mineral waters industry for instance such an apparatus
enabling the liquid to be withdrawn at a reduced pressure will be of the utmost
importance and use.
Figures 1 to 10 of the accompanying drawings illustrate the apparatus.
Figure 1 being a section.
Figure 2a front elevation of the complete apparatus the remaining figures
showing details of construction Figs. 4 to 10 being in a larger scale.
A is a metallic plate by which an elastic plate B is held against a flat circular
flange B projecting on the interior of the casing R so as to close the chamber so
formed in an air-tight manner.
The liquid, under high pressure arrives from the right-hand side, into the
apparatus through the pipe H passes through the valve head G flows along the
faces of a triangular prism E, enters into the casing R and produces in its interior
a certain pressure according to the discharge or filling pipes being more or less
open. Two such discharge pipes are shown in the drawing but of course one or
any other number may be arranged if desired.
In the inlet pipe containing the valve GE is arranged a spring which rests
against a shoulder G of the valve and presses the elastic ring of the latter against
the circular projecting flange of the branch L. In this way a perfect joint is
ensured when the pressure of the liquid acts and when the valve operates under
this pressure and the counter pressure exercised by the boss C secured to the
elastic plate B.
The union piece K is screwed on the branch L and may be easily removed in
order to examine, clean or repair the parts. The cover Q is screwed into the
casing R and ensures a perfect joint between B and B'. In order to regulate the
pressure under which it is desired to draw off the liquid arriving at F under
high-pressure, that is to say to discharge it through the pipe or pipes provided
for filling other receptacles, it is only necessary to turn the thumb-nut P so as to
screw it to a greater or less extent on the branch of the cover which is provided
externally with a screw-thread. As a result of this, an adjustable plate suitably

page_text: arranged in a recess of the nut or cup P, is pressed to a greater or less extent
against the spring N, and the latter against the part M of the plate A which
transmits the pressure to the face D of the valve E and so removes the ring G
from its seat in order to allow as much liquid under high pressure to be admitted
into the apparatus as will establish in the interior of the latter the desired pressure
suitable for drawing off from the apparatus.
In order that different details of the hereinbefore described apparatus may be
better understood, I have illustrated in Figures 4 to 8 on a larger scale the following
pieces; the nut P Figure 4, cover Q Figure 5, the plates A B Figure 6, the
casing R Fig. 7, and the union K K Fig. 8. Figure 9 shows the valve D E G and
Figure 10 is a cross section in line X X Fig. 7 through the branch L.
In order to facilitate the regulation of the pressure in the casing a suitable
pressure gauge may be attached thereto, as shown in Figures 1 and 2.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is :-
1. A regulating device for enabling liquids whether saturated with gases under
high pressure or not, to be drawn off at a desired pressure whereby the pressure at
which the liquid is to be drawn off may be maintained and controlled consisting of
a casing provided with a pressure gauge as having an elastic spring controlled
diaphragm and regulating cap or nut and a spring controlled admission valve
substantially as and for the purposes described.
2. The combination and arrangement of parts forming the complete fluid pressure
regulating device, substantially as described and illustrated in the accompanying
drawings.
