Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an apparatus for magnetically treating water to reduce scale buildup and for improving combustion efficiency and reducing air pollutant production in gasoline, gasol, diesel oil, propane,
It relates to an apparatus for magnetically processing liquid or gaseous fuels such as natural gas, oil, etc.

As energy shortages, particularly petroleum-based fuels, reach global reach, the need to efficiently burn such fuels becomes increasingly important.

Today, cars are probably the biggest consumers of oil, so if combustion methods were more efficient, significant savings could be made between gasoline and diesel fuel, allowing the car to be driven farther with a given amount of fuel. be able to.

Furthermore, air pollution has increased significantly in recent years due to the increased use of passenger cars and trucks, and it is desirable to produce vehicle engines that reduce pollutant emissions.

Increasing fuel efficiency and reducing pollution are important not only for vehicles, but also for heating systems and power plants that burn hydrocarbons such as oil, natural gas, and propane.

Significant efforts have been made to reduce air pollutants from engines, furnaces, power plants, etc., but the primary focus has been on devising techniques to burn fuel more efficiently, thereby reducing waste emissions. In particular, it has been placed in the treatment of exhaust and chimney emissions.

A beneficial result of more efficient fueling is that the fuel is burned more completely, reducing the amount of hydrocarbon waste released.

The apparatus of the present invention is useful for increasing the combustion efficiency of fuel by treating raw fuel with a magnetic field.

In the case of vehicles, this results in increased range, and in the case of heating and energy conversion devices, an increase in heat output for a given amount of fuel can be achieved.

The apparatus of the present invention is also useful for magnetically treating water to reduce scale build-up in pipes, ductwork, and other equipment through which water flows.

A very common problem in systems and equipment that use large amounts of water, such as boilers, dishwashers, ice makers, etc., is the accumulation of scale on surfaces that come into contact with the water.

The problem is that the water has a high mineral content and therefore
This is particularly serious where water needs to be "conditioned" either by chemical action or by magnetic water treatment devices of the general type to which this invention relates.

An example of such a magnetic processing device is U.S. Pat.
No. 1,807, No. 4,050,426 and No. 4.1
No. 53,559.

Basically, such devices consist of longitudinally spaced, concentrically positioned, plated iron or black iron casings made of magnetic material such as iron encased within a non-magnetic jacket. It includes an elongated magnet having a plurality of magnetic poles.

The deflected magnet in the jacket is center flushed by a pair of stepped collars affixed thereto, which collars are center flushed by a pair of layered inserts.

Alternatively, the jacketed magnets can be centered by elastic tapered sleeves, which are wedged between the magnet jacket and the metal-plated casing.

This general type of equipment is well known and prevents corrosion and prevents scale build-up by forming a loose slurry of calcium and other minerals present in hard water, which is then removed by blow-off or water. Can be easily removed from the system.

For example, in many applications, such as furnace humidifiers, it is important that the magnetic processing device be housed in a compact and compact housing, and for this reason, available space is at a premium.

Furthermore, the efficiency of water treatment depends on the strength of the magnetic field within the treatment chamber and the effective length of the treatment chamber itself.

It is therefore desirable that the processing chamber be free of obstructions that obstruct the available processing space and that water, after entering the processing chamber, be introduced into the processing chamber as quickly and over a short distance as possible to completely fill it.

Also, care is taken to ensure that the strength of the magnetic field generated by the magnet is limited to the confines of the annular processing chamber so that all of the available magnetic flux is utilized.

An important requirement in doing so is to completely magnetically isolate the magnet from the support structure and to complete the magnetic circuit with an iron casing surrounding the magnet and magnetically insulated from the magnet.

The above-mentioned U.S. Patent No. 4,153.5594 includes:
The magnet structure is centrally supported within the iron casing by a pair of non-magnetic, elastic sleeves, the sleeves being compressed between the magnet structure and the iron casing and engaging them at both ends. has been done.

Additionally, the magnet is frictionally retained within the jacket by a pair of plastic end caps which further insulate the magnet and also prevent water from contacting the magnet and corroding it. Helpful.

The end of the inner casing is partially opened around the end of the plastic sleeve to provide a positive-action lock to prevent relative axial movement between the inside of the casing and the sleeve. This is to form a .

Although the frictional engagement between the inner casing and the plastic end cap and between the inner casing and the resilient sleeve holds the electrode structure in place during normal use, it may be dropped during shipping or installation. Violating the device thereby causes the magnet to move axially, thereby partially or completely blocking the set of holes.

Obviously, this prevents water or fuel from flowing properly through the device.

Furthermore, the inner casing can be moved as a unit with the elastic sleeve relative to the iron casing, and such movement may also partially or completely block a set of holes or cause an annular treatment. It may also result in distorting the chamber or blocking the holes, thereby distorting the treatment chamber and thereby reducing water or fuel treatment efficiency.

The magnet and magnet casing assembly may be displaced axially by the severe water hammer effects that occur in the water supply system when the treatment device is used as a water conditioner.

In one embodiment of the invention, the inner casing in which the magnet is placed has its tubular ends tightly engaged with the inner casing so that the end attachment is securely locked against axial displacement relative to the conduit. It is an improvement over the processing apparatus described above in that it is sized and mounted in a recess provided in the conduit.

The end fittings, in which the inner casing is screwed to the iron casing, are held axially stationary relative to the pipeline, so that these parts maintain a suitable spacing relationship regardless of shocks to the processing equipment. is maintained.

This arrangement allows liquid to flow into the inner casing with minimal turbulence, thereby reducing pressure drop.

When the end of the inner casing is received within the conduit recess, the end fitting securely locks it against axial movement of the inner casing relative to the conduit and the iron casing. In some cases, difficulties are encountered during the assembly of these parts.

If an end-fitting conduit is screwed into the iron casing at the end of the inner casing beyond the point where it contacts the bottom of the conduit recess, the inner casing will deform axially. I am forced to do it.

If this were to occur, the inner casing could twist outward, reducing the volume of the annular treatment chamber and supporting the inner casing and the magnet, even if exposed to the liquid flow. The liquid-tight seal between the end cap and the end cap may be ruptured.

In one variant embodiment of the invention, each end fitting is such that the recess in the conduit is replaced by a tapered passageway, the passageway having a minimum internal diameter smaller than the outer diameter of the inner casing and a maximum inner diameter smaller than the outer diameter of the inner casing. larger than the diameter.

Thus, as the end camps are screwed into the iron casing, the tapered passages contact the ends of the inner casing and deform the ends of the casing slightly radially inward.

This allows the inner casing to sit uniformly on the end-fitting conduit and to provide a tight seal between the inner casing and the end-fitting conduit.

Furthermore, the inner casing is prevented from axial movement because the end fittings are tightly compressed by the conduit.

The tapered passage continues beyond the axial row ends of the inner casing, thus preventing further axial movement of the inner casing as the ends of the inner casing are further compressed by the tapered passage.

to prevent movement relative to the inner casing.
A portion of the tubular end portion of the inner casing is inwardly deformed to form a locking projection that engages the capped magnet to prevent axial movement of the magnet.

This protrusion cooperates with a seating engagement on the inner casing to provide structural integrity to the equipment to withstand severe shaking due to water hammer when the equipment is dropped during shipping or when the equipment is used as a water conditioner. Retain your sexuality.

The structural arrangement of the processing device according to the invention also allows the vehicle to refuel due to repeated and sometimes violent agitation when the vehicle travels over uneven ground, which would otherwise result in relative movements between the parts that make up the device. It is also advantageous when used as a processing device.

In particular, the present invention provides an apparatus for magnetically processing fluids such as water and liquids and gaseous fuels, the apparatus comprising an elongate tubular intermediate casing of magnetic material, opposite ends and at least two axes. an inner casing of non-magnetic material having vertically spaced magnetic poles, an open tubular end portion extending beyond the ends of the magnet, and an inner casing connected to the ends of the intermediate casing and extending outwardly A pair of end fittings having open fluid passageways include a conduit.

The end fitting is such that the conduit is spaced apart from the magnet by receiving each of the tubular end portions of the inner casing and is open in its direction to space the inner casing from the intermediate casing, thereby creating an annular treatment between the two. It includes a recess forming a chamber.

The recesses have respective end fittings in fluid communication with fluid passageways of the conduit, and each tubular end section is provided with an aperture to define a fluid flow path from within the tubular end section to the processing chamber.

An outer casing made of copper or other suitable material is end-attached to the conduit and received by downwardly curved shoulders and spaced outwardly from the intermediate casing.

The row casing prevents the intermediate casing from contacting other ferrous materials once the processing equipment is installed.

According to an embodiment of the invention, the end The attachment is such that when the conduit is threadedly secured to the iron casing, the ends of the inner casing are pushed inwardly so that the inner casing and the end fitting form a tight fit between the conduit.

This prevents the inner casing from moving both axially and radially.

A further advantage of this embodiment is that the lengths and end fittings of the inner casing and the iron casing are more or less critical to the extent to which the conduit is threaded into the iron casing.

This means that the end fittings do not axially abut the conduit and the inner casing, and they are threaded into the iron casing with the only effect that the inner casing deforms slightly inward. This is because the end fitting allows the conduit to continue sliding on the inner casing when it is installed.

The outer diameter of the inner casing, which is a dimension that is sometimes difficult to hold within tolerances, is also somewhat limited because the ends of the inner casing are automatically sized by having them deformed inwardly by tapered passages. is important.

This relationship is also advantageous from the point of view of precisely centering the inner casing within the iron casing to form an annular treatment chamber precisely concentric with respect to the magnetic field.

Referring to the drawings, a magnetic water and fuel treatment system according to the present invention includes an outer casing 10 made of a non-magnetic material such as copper.
and a pair of fluid fittings, also made of non-magnetic material such as brass, are provided with conduits 12,14.

Attach flanges 16 and 18 to pipes 12 and 14, respectively.
are provided, the flanges abutting the ends 20, 22 of the outer casing 10.

It will be seen that the outer casing 10 is attached to the annular shoulders 24.26 so that the outer surface 28 of the casing 10 is aligned with the outer surface 30.32 of each of the conduits 12.14.

The hexagonal head 34.36 allows the installation of the conduit 12.14 to be tightened with a standard wrench and the adapter 38.
40 is provided with a stepped outer surface 42.46 to facilitate connection of a flexible hose 46.48;
For example, it may be a fuel pipe for an internal combustion engine.

The hoses 46, 48 are tightened by hose clamps 35.

Depending on the specific application of the magnetic processing device, the installation may be in line 1.
2.14 may be provided with standard pipe threads for connection to pipe or compression fittings may be provided with conduit for connection to thin-walled copper pipe or tubing.

The last two types of connections are used when the treatment equipment acts as a water regulator, in the case of furnaces or heat conversion equipment, or in the case of natural gas or oil processing.

In the illustrated embodiment, which is specifically adapted to be connected to an engine fuel conduit, the stepped outer surface 42,44 is connected to the hose 46.
．． It digs into the inner surfaces 50 and 52 of 48 to resist curling and at the same time facilitate installation.

Obviously, other installations of conduits and connections can be used depending on the environment and the intended use of the treatment device.

In the present invention, the term "non-magnetic material" includes, for example, copper,
Brass, PVC, nylon and Derin
It refers to a substance with very low magnetic permeability, such as virtually no magnetism.

"Magnetic" materials are materials that exhibit high magnetic permeability, such as iron and some types of copper.

A tubular intermediate casing 54 of a ferromagnetic material with high magnetic permeability, such as galvanized iron or steel, is mounted and threadedly connected to the conduit 12.14 by threads 56.58.

If desired, the threads 56° 5B can be coated with pipe grease or wrapped with Teflon tape for installation in conduit 12.
14 and the casing 54 can be sealed watertight.

The intermediate casing 54 has an outer diameter that is smaller than the inner diameter of the outer casing and defines an annular space 60 therebetween.

Inside the intermediate casing 54 is a tubular inner casing 6 made of a non-magnetic material such as copper and open at both ends 64 and 66.
2 is positioned.

The inner casing 62 is received in recesses 6B, 70, respectively, in the mounts 12.14, which mounts are open to the center of the processing apparatus and in fluid communication with passages 72.74, respectively. .

The inner casing 62, the attachment of the conduit 12.14 and the intermediate casing 54 are arranged so that when the conduit 12.14 is screwed into the intermediate casing 54, the axial edges 76.78 of the inner casing 62 fit into the respective recesses. Bottom 8 of 68°70
It is sized to match 0.82.

The recesses 6B, 70 are located at the ends 64, 66 of the inner casing 62.
are sized to fit tightly into the ends 64, 66 when the processing device is assembled.

Each attachment is to the tapered wall 84.8 of the conduit 12.14.
6 connects the ends 64° 66 of the inner casing 62 to the recesses 6B,
It will help guide you within 70.

The particular arrangement shown in FIG.
2 directly into the casing 62.

When liquid enters the enlarged chamber, the laminar pattern is disrupted and turbulent flow occurs.

Turbulent flow results in a large pressure drop, reducing efficiency and requiring the use of larger volume equipment.

Flowing the liquid directly into the inner casing 62 maintains a substantially laminar flow and minimizes pressure loss.

Mixing of liquid and air is also reduced.

Retained within the inner casing 62 are elongated permanent magnets 88, preferably having a composition of cobalt, nickel, aluminum, copper and iron, magnetized along their longitudinal axes and designated by the symbols rNJ and "S", respectively. and a plurality of longitudinally spaced magnetic poles.

Magnet 8B is substantially homogeneous in composition and, in the illustrated embodiment, consists of two magnetic regions extending laterally of the magnet and having magnetic moments arranged in opposition such that magnetic poles of opposite polarity exist along the length of the magnet. Become.

Such magnets are manufactured by applying two longitudinally displaced static magnetic fields of opposite polarity onto a magnetic material.

The number of poles of a particular magnet depends on the size of the processing device and the desired flow volume; therefore, magnets with as few as two poles are most efficient for very small volume devices.

Preferably, the magnet is made of a material that produces high energy and has high coercivity and coercivity, such as Alnico.

A wide variety of commercially available magnets and magnet materials are available within these desirable constraints.

Magnet 88 is provided with a pair of resilient end caps 90, 92 which are fitted onto opposite ends of the magnet and compressed between the magnet and the inner surface 94 of inner casing 62 to force magnet 88 into a frictional position. It is held in

If the processor is used as a water conditioner, the cap 90.92 is preferably made of polyethylene, and if the processor is used as a fuel processor, the canknob is made of brass.

In both cases, the cap 90.92 also serves to space the magnet 88 from the interior ff194 of the inner casing 62.

Inner casing 62 is centered within intermediate casing 54 to define an annular processing chamber 96 defined by an inner surface 98 of intermediate casing 54 and an outer surface 100 of inner casing 62 .

To allow fluid flow within the tubular end portions 64 , 66 of the inner casing 62 and the annular processing chamber 96 .

Tubular end portions 64,66 each have holes 102,104.
is cut out.

The holes 102 and 104 are angularly offset from each other by 1800 degrees so that water or fuel entering the process chamber 96 through one of the holes will enter the process chamber 96 before exiting the other hole.
Rotate 180° around the axis.

By configuring as described above, more of the processing chamber can be utilized since otherwise a portion of the processing chamber may receive little or no fluid flow.

Depending on the flow volume of the treatment device, additional holes (not shown) may be cut in the tubular end section, and if two additional holes are provided, these additional holes may overlap the existing holes 102-10.
4, respectively, but in that case the holes 102 and 104 are displaced from each other by 90 degrees instead of 1800 degrees.

In many cases, it is desirable that the cross-sectional areas of passageways 72, 74, holes 102, 104, and process chamber 96 be selected to maintain the pressure drop at a low level relative to the rated flow volume of the process device.

The frictional force between the plastic or brass end cap 90° 92 and the inner surface 94 of the inner casing 62 is generally sufficient to prevent axial movement of the magnet and end cap assembly during normal use. However, during shipping or installation of the device, if the device falls from one end, the holes 102, 10
This may result in one of the four being occluded.

This means that the magnet and end cap assembly has holes 102,1
04, and the blockage of either hole will prevent fluid from flowing through the blocked hole 102, 104, i.e. will significantly reduce the flow rate and therefore the process. The throughput of the device is significantly reduced.

When the treatment device is used as a water conditioner, a reduction in the throughput of the device can result in an undesirable loss of line pressure, and when the treatment device is used as a fuel processor. In some cases, the engine may stall due to insufficient fuel supply to the carburetor or fuel injector.

To securely lock the magnet and end cap assembly within the inner casing 62, the end portions 64, 66 of the inner casing 62 are connected to the edges 110, 112 of the holes 102, 104.
The portions shown in FIGS. 5 to 7 are wrinkled inward as indicated by reference numerals 106 and 108 (FIGS. 5 and 6).

Preferably, the crumple portion is positioned at the inner corner closest to magnet 88, indicated at 114.

The crimped portions 106, 108 extend beyond these crimped portions just inside the holes 102 and 104 to the end cap 9.
0.92 is formed with an inwardly protruding locking protrusion 116 that prevents movement.

The structure described above is designed to concentrate the magnetic field produced by the magnet 88 within the annular chamber 96 in the immediate vicinity of the annular chamber while at the same time isolating the magnetic field from the support structure.

Because the intermediate casing 54 has a high magnetic permeability, the magnetic flux generated by the magnet 88 extends radially from the magnet, passes through the intermediate casing 54, and then returns to the magnet 88 without departing from the process chamber 96.

By suppressing the magnetic field in this manner, water or fuel flowing through the treatment device into the magnetic field is treated with maximum efficiency.

Magnetic field isolation is further improved by the use of non-magnetic materials for the outer casing 10, the attached conduits 12, 14, the inner casing 62 and the plastic or brass end caps 90,92.

First insert the magnet 88 into the inner casing 62 and then press the brass end cap 90.92 onto the end of the magnet so that the cap is compressed between the magnet 88 and the inner surface of the inner casing 62. The processing device is assembled by

However, if the plastic end cap 90,
92 is used, these caps are first fitted onto the ends of the magnets 88, and the assembly is then attached to the inner casing 6.
Pushed into 2.

After the magnet 88 and end cap 90.92 are secured,
The tubular end portions 64 and 66 are crimped as shown in FIGS. 5 and 6.

Next, the inner casing 62 is installed in the recess 70 of the conduit 14.
and then the intermediate casing 54 is installed in the conduit 1.
4 is screwed loosely.

The outer casing 10 is then slip-fitted around the intermediate casing 54 and guided over the annular shoulder 26.

The other attachment is such that conduit 12 is threaded around the other end of intermediate casing 54 and, as previously mentioned, the attachment is such that tapered surface 84 of conduit 12 is threaded around end 64 of inner casing 62. Helps guide into recess 68.

The attachment is then screwed tightly around the intermediate casing 54 until the ends 76.78 abut the axial surfaces 80.82 of the recesses 6B, 70.

The outer casing 10 is preferably sized to fit snugly between the shoulders 80.82 of the conduit 12.14 when the attachment conduit 12.14 is tightened.

The threaded portions 56,58 of the intermediate casing 54 are preferably mounted with a slight taper so that a fluid-tight seal is formed when the conduit 12.14 is tightened onto these threaded portions.

FIG. 8 shows a method of installing the processing device described above into a gasoline fuel engine 11B of an automobile.

A fuel processor, generally indicated at 120, is preferably connected to a fuel conduit, which serves to form sections 46, 48 as close as possible to the inlet of the carburetor 124.

Thus, when fuel is pumped from fuel storage (not shown) by fuel pump 126, fuel is pumped through fuel conduit 46, passage 7
2, through the tubular end section 64, the bore 102, the annular treatment chamber 96, the bore 104, the tubular end section 66, the passage 74 and the fuel conduit section 48 into the carburetor 124.

As the fuel passes through the annular treatment chamber 96, it is exposed to a dense, generally radial magnetic field created by the magnet 88.

The effect of magnetic fields on fuel is not well understood, but
This process allows the vaporized fuel to disperse more quickly as it enters the enlarged area of the combustion chamber, thereby allowing for more complete combustion, improving fuel efficiency and performance, and reducing exhaust emissions. Become.

Although not shown, device 120 can also be used in diesel engines by connecting it to the fuel conduit in front of the fuel filter and fuel injector.

Furthermore, the apparatus of the present invention can be used to treat propane in vehicles and other equipment, as well as natural gas and oil, such as in furnaces and power plants.

In either case, it is important that the fuel is treated before it reaches the carburetor, fuel injector nozzle, burner, etc.

As previously mentioned, treatment equipment is used to condition or treat water, in which case the equipment is installed in the water supply line before the boiler, humidifier, ice maker, or other equipment in question. Connected directly in series.

Although the water and fuel processing device has been shown and described as having a generally symmetrical overall shape around a straight axis,
Other shapes are also possible.

Although the magnetic poles of magnet 88 are shown in connection with the preferred embodiment as an N-8-8-H arrangement, a 5-NN-8 arrangement is also effective.

Furthermore, the number of magnetic poles can be increased or decreased depending on the space and flow volume of the device.

9-11 illustrate an alternative technique for locking the magnet and end cap assembly against axial movement within the inner casing 62.

U.S. Patent Application No. 12 filed February 14, 1980
As in No. 1,646, holes 102.104 are
inserted into the hole as shown in the figure and relative to the longitudinal axis.
At an angle of 5 degrees, the edge 132 of the hole 102 is
34 is crimped by tool 130 which is pivoted downwardly to bend it downwardly.

The inwardly deformed edges 136, 13B form a locking protrusion on the inner surface of the inner casing 62 to prevent axial movement of the magnet 88 and cap 90.92.

An additional advantage of this shape is that the holes 10
2 , 104 are shaped so that they form a deflecting surface that pumps incoming water or fuel into the annular treatment chamber 96 and then pumps it out of the chamber 96 and toward the outlet end 66 .

This creates an easy path for the liquid to flow through and therefore results in less pressure drop than if the liquid had to make a right angle turn before beginning to flow into the process chamber 96 and then another right angle turn as it leaves the process chamber 96.

FIG. 10 shows a crimping device 130 used to deform holes 102,104.

The device 130 includes a tool portion 1 having a handle 130 and an upper surface 147 adapted to be grasped by a person shaving the hole 102.
43, and this surface 147 has the same curvature as the inner edge of the holes 102, 104 when the device 130 is inserted into the holes 102,104.

If desired, the underside of tool portion 143 is concave with a gentle taper toward handle 141, as shown in FIG.

As previously mentioned, one of the problems with the embodiment shown in FIG. ,7
surface 80.82 of end 76.0 of inner casing 62.
78 is desirable.

If the end fitting is tightened too tightly to the intermediate casing, as is likely to happen if the row casing 10 is too short, the inner casing 62 will bend at the location of the hole, causing the inner casing to bend. The intermediate casing 54 is brought into direct contact with the intermediate casing 62.

This would partially clog the annular processing chamber 96 and reduce the efficiency of the apparatus.

Furthermore, the inner casing 62 has end caps 90,9.
2, thereby exposing the magnet 88 to the liquid.

Yet another difficulty with the first embodiment is that the inner casing 62
However, the end fittings mean that the rear of the inner casing 62 must be within very tight tolerances to avoid rattling within the conduits 12,14.

FIG. 12 shows one end of the fuel processor or water conditioner of the present invention, with the iron casing and magnet assembly omitted for clarity.

The same goes for the other end of the device.

An inner casing 142 within the magnet (not shown) is supported by an end cap (not shown) similar to the embodiment of FIG. 1 and is disposed concentrically within the row casing (not shown). The end fitting is directly supported by conduit 140.

It should be noted that the structure of the row casing, intermediate casing and magnets associated with the embodiment of FIG. 12 is the same as that of the embodiment of FIG.

At the end, the conduit 140 includes a tapered surface 156 that decreases in diameter substantially uniformly in the axial direction from the magnet.

Thus, when the end fitting is such that when the conduit 140 is screwed around the iron casing by the threads 152 provided in the section 150, the end 158 of the inner casing 142 is radially oriented as shown in FIG. It is transformed inward.

This provides a tight fit between the force surface 157 of the inner casing 142 and the tapered passageway 156, thus preventing axial and radial movement.

It will be appreciated that due to the compression between the inner casing 142 and the tapered passageway 156, the end fitting will resist axial movement of the inner casing 142 relative to the conduit 14.

For example, assume that the row casing supported by the annular step 153 is cut slightly shorter than its preferred length.

In this way, the end-fitting is carried out with conduit 140 around the middle casing, and the row casing is end-fitted with conduit 140 around the intermediate casing.
The result is that the screw is screwed in more than necessary before it hits zero.

However, this is not a problem for the inner casing because the inner casing 142 continues to be deformed inwardly, so there is always a tight fit between the inner casing and the tapered passage.

The relative sliding movement between passageway 156 and force surface 157 of inner casing 142 prevents inner casing 142 from bending.

In fact, end fitting can even tighten the conduit 140 to such an extent that the inner casing 142 protrudes beyond the tapered passageway into the area defined by the tapered passageway 154, which is generally undesirable.

To facilitate insertion of the inner casing 142 into the tapered passageway 156, the enlarged diameter end of the casing is preferably larger than the outer diameter of the inner casing 142.

The smallest internal diameter at the axial end of the tapered passageway 156 is determined by the inner casing 1 to provide the desired tight fit.
42 at the end 158.

The end fitting is provided in conduit 140 with a hexagonal section 146 so that it can be screwed around the intermediate casing.

Alternatively, the embodiment of FIG. 12 can be configured to attach to a fuel hose, compression attachment to a conduit, or any optional liquid conveyance means depending on the application.

In the embodiment of FIG. 12, the magnet 88 is first inserted into the inner casing 142 and then the brass end cap 90 is inserted into the inner casing 142.
, 92 around the end of magnet 88 such that the end cap is compressed between magnet 88 and the inner surface of inner casing 142 .

However, if plastic end caps are used, these end caps are first fitted around the ends of magnet 88 and the assembly is then press fit into casing 142.

After the magnet 88 and cap 90.92 are secured, the tubular end portion is crimped as shown in FIG. 5 in the embodiment described above.

The inner casing 142 is then attached to the end of the conduit 140.
, and the intermediate casing is loosely screwed onto the threads 152 .

The outer casing 10 is then slipped-fitted around the intermediate casing and guided onto the annular shoulder 153.

The other attachment is due to the fact that the conduit 140 is threaded around the other end of the intermediate casing 54 and that the largest row of tapered passages 156 is slightly larger than the outer diameter of the inner casing 142. You will be guided.

The installation is then performed with conduit 140 being threaded around intermediate casing 54 and tapered passageway 156 being force fit around end 158 of inner casing 142 as shown in FIG. It is transformed inward as if

The flange portion 150 is screwed around the intermediate casing 54 until it abuts the end of the outer casing 10 .

Although the invention has been described in terms of one preferred embodiment, it will be appreciated that further variations may be made to this embodiment.

Accordingly, the present invention is susceptible to various modifications, uses and applications in accordance with its general principles, and such modifications, uses and applications are also known or common practice in the art to which the invention pertains and are not limited to the claims set forth above. This falls within the scope of .
