Abrégé français

Un dispositif de réglage de la flamme comprenant un réservoir destiné à recevoir un liquide et comprenant une partie supérieure et une partie inférieure couplée à un coupleur par des tuyaux. Le coupleur est couplé à un générateur de gaz. Un dispositif de commande est disposé entre le coupleur et un tuyau supérieur et est utilisé pour commander l'écoulement du gaz à travers les tuyaux et pour ajuster l'écoulement du gaz hors du réservoir. Le gaz est un combustible gazeux et est fourni à une installation pour générer une flamme. La température produite par la flamme peut donc également être réglée.

Abrégé anglais

A flame adjusting device includes a tank for receiving a fluid and includes an upper portion and a lower portion coupled to a coupler with hoses. The coupler is coupled to a gas generator. A control device is disposed between the coupler and an upper hose and is used for controlling the gas to flow through the hoses and to adjust the gas flowing out of the tank. The gas is a gaseous fuel and is supplied to a facility for generating a flame. The temperature generated by the flame may thus also be adjusted.

TITLE: FLAME ADJUSTING DEVICE FOR OXYGEN AND
HYDROGEN GENERATOR

BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to a flame adjusting device and more
particularly to a flame adjusting device for an oxygen and hydrogen generator.
2. Description of the Prior Art.

Typical oxygen and hydrogen generators may be used for generating
gaseous fuel, particularly the oxygen and/or the hydrogen. The gaseous fuel
generated by the generators may be supplied to a torch, for example, for
generating a flame to conduct cutting or welding process. The gaseous fuel
and thus the flame may not be adjusted.

The present invention has arisen to mitigate and/or obviate the afore-

described disadvantages of the conventional oxygen and hydrogen generators.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a
flame adjusting device for adjusting the gaseous fuel from an oxygen
and hydrogen generator and in order to adjust the flame generated by
the gaseous fuel.

In accordance with one aspect of the invention, there is provided a
flame adjusting device for a gas generator, comprising:

a tank for receiving a fluid and including an upper portion, a lower
portion, and an outlet;

a coupler coupled to the gas generator for receiving gas generated
by the gas generator;

a first hose coupling said coupler to said lower portion of said tank
for allowing the gas from the gas generator to flow into said tank and to
flow through the fluid received in said tank and to flow out through

said outlet of said tank;

a second hose coupling said coupler to said upper portion of said
tank for allowing the gas from the gas generator to directly flow into
said tank, without flowing through the fluid received in said tank, and
to flow out through said outlet of said tank together with the gas

flowing through the fluid received in said tank; and


CA 02309490 2007-03-22

means for controlling the gas flow through at least one of said first
hose and said second hose.

The controlling means includes a control valve provided between
the coupler and the second hose for controlling the gas to flow through
the first hose and the second hose. The tank includes an indicator for

indicating a level of the tank. A facility such as a tank is coupled to the
outlet of the tank for receiving the gas from the tank in order to
generate a flame.

Further objectives and advantages of the present invention will
become apparent from a careful reading of a detailed description
provided hereinbelow, with appropriate reference to accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, and initially to FIGS. 1-3, a flame adjusting

device in accordance with the present invention is provided and coupled to
a nozzle 12 of an oxygen and hydrogen generator 11 for receiving the

5 gaseous fuel, such as the oxygen and/or the hydrogen. One example of the
oxygen and hydrogen generator 11 is disclosed in U.S. Patent No.
6,068,741 to Lin issued on May 30, 2000 and is taken as a reference for the
present invention. The flame adjusting device andlor the oxygen and
hydrogen generator 11 may be disposed in a housing 10 or the like.

The flame adjusting device comprises a tank 20 including a port 21
for adding into or for drawing a fluid 28 from the tank 20 and including an
indicator 23 coupled to the side portion for indicating the fluid 28 level in
the tank 20. The fluid 28 may be selected from gasoline, alcohol, alkyl
group, or alcoholic fluids, etc. Two hoses 40, 50, couple the lower and the

upper portions of the tank 20 to a coupler 30, such as a three-way valve,
and a control valve 51 is provided between the coupler 30 and the hose 50
for controlling the gaseous fuel through the hoses 40, 50. The tank 20
includes an outlet 22 for supplying the gaseous fuel out to a facility, such
as
a torch 24 (FIG. 1) and for generating a flame to conduct a welding or

cutting process. It

is preferable that the hose 50 is coupled to the tank 20 at a position lower
than
the outlet 22.

In operation, as shown in FIG.3, the control valve 51 may control the
gaseous fuel to flow to the facility 24 through the hose 50 and the outlet 22
only. The gaseous fuel may generate a flame of a temperature up to 3000 C,

depending on the gaseous fuel generated by the generator 11. As shown in
FIG.4, the control valve 51 may control the gaseous fuel to flow to the
facility
24 through the hose 40 and the fluid 28 only. The gaseous fuel may be mixed
with the fluid 28 to form a mixed gas which generate a flame of a temperature

about 900 C, depending on the gaseous fuel and the fluid 28. As shown in
FIG. 5, the control valve 51 may control the gaseous fuel to flow to the
facility
24 through the hose 40 and the fluid 28 and the hose 50 separately. A portion
of the gaseous fuel may be mixed with the fluid 28 to form a mixed gas which
generate a flame of a temperature ranging from 900 C to 3000 C, depending
on the gaseous fuel and the fluid 28 and depending on the gaseous fuel

flowing through the hoses 40, 50.

Accordingly, the flame adjusting device in accordance with the present
invention may be used for adjusting the gaseous fuel from the oxygen and
hydrogen generator and may be used to adjust the flame generated by the
gaseous fuel.

Although this invention has been described with a certain degree of
particularity, it is to be understood that the present disclosure has been
made
by way of example only and that numerous changes in the detailed
construction and the combination and arrangement of parts may be resorted to

without departing from the spirit and scope of the invention hereafter
claimed.
