Venturi Omega is a hydro-pneumatic-device made up of two principal elements and aggregate. The aggregate may be a single element or a composed whole of many items. The two principal elements are 1 the membrane and a closing element or flow-stopper: 2 the ball, sphere or stopper. Some of the performances of the device are the following: The self-closing of the device The displacement of the ball and or the membrane which allows further actions. The displacement is originated by changes in the pressures relationship between the pressures on both sides of the membrane, the inner- and outer-side The increasing closing-force whit bigger softness of the ball The easy opening of the device and the easy handling of the flow-control, flow-monitoring and flow-measure, particularly pressure- and differential-pressure-measures. The Venturi Omega is a versatile elastic-dynamic-device. Till jet we have developed among others the following useful devices: A safety-valve whit all the working elements or machinery lying in the outer side of the membrane thus not contaminating the fluid and not being corroded and wearing away by the flow. An airplane-speedometer A barometer or atmospheric-pressure-monitoring-device A pneumatic "no hands" tap A top-level-control-device Several pressure- and differential-pressure-measure- and monitoring-devices The Venturi Omega balloons.

Description

Venturi Omega device

1. - Inventions field:

The inventions fields are the hydraulic, the pneumatic and the hydro-pneumatic, in particular in the fields of valves, differential-pressure-devices and sensors.

2. - The state of the technique:

The antecedents of the invention are to be search in mechanisms using the Venturi- effect and using the differential-pressure to obtain a farther action and mechanism using the described opening through the membrane or through the ball in several devices. The Venturi effect, the displacement of a membrane due to pressures- relationship- changes, the fluid velocity-measure- and planes-speed- measure instruments, the signal-release or a further-action-release, the pressure limit devices, the atmospheric- pressure-monitoring, the easy opening and flow-control of valves are some of the items or fields of the preceding or antecedent devices to our device.

3. - Inventions description:

Our invention, whit two principal parts: the ball (elastic or not elastic) 2 and the mainly elastic membrane 1 as shown in image Figure 1 , takes advantage of the following facts::

a) The Venturi-effect

b) The displacement of the membrane due to differential-pressure changes within our device or between our device and the surroundings fluid Figure 3

c) The easy opening of the device, when closed, by open moving of the ball through pushing the membrane as shown in Figure 4 case a) or direct through the ball as shown in case b).

The invention is a manifold device, because of the many features it contains you can compound them in many ways. The invention, as we said, is a device made up of two principal elements the membrane and the ball plus a third element the aggregate which can be composed of one of more necessary elements for the right running or best functioning of the mechanism or instrument.

Our device uses one or more of the following advantages:

The device has two possible positions: the open position and the closed position.

a) When the dispositive is open and the ball is close by the open drain, or tap outflow, the ball is impelled towards the membrane, because of the Venturi effect: Figure 1 and this is our:

First invention-advantage:

The Venturi effect is which is mathematically expressed by the Bernoulli equation, which is the resulting of the continuity of the passing flow and the energy conservation law of flows. That means that the passing stream is steady, since the same amount of fluid is passing through all the different spaces perpendicular to the stream and the fact that the sum of the different kinds of energy is also the same all the way through the entire stream.

Since this is also valid for our device it results that the velocity will be greater in the narrower places as in the wide ones, thus causing an acceleration of the stream in those narrower places an exactly this velocity increment causes a pressure-drop (Bernoulli). And because of the pressure-drop, the free swimming ball tends to go to the narrower parts of the stream. Going in direction of the narrower space this space will be again narrower and the ball will be steady and successive driven always with constantly increasing

acceleration and speed. Just a split second before the ball crash against the membrane the velocity reaches its greatest value according to the amount of energy the stream owns and the pressure is nearly as small as cero that means practical vacuum. In other words: exactly before the crash the stream and the ball as a system have practical only kinetic- energy, the impulse reaches, at the very last moment of this phenomenon, its greatest value and the ball will be catched by the elastic membrane like a baseball by a catchers- glove, exchanging in a split second all of the kinetic-energy in elastic or form-changing- energy that is the membrane goes back till the forces produced by the outer and inner pressure come into equilibrium whit the elastic force produced by the membranes deformation acting now as a slingshot in its back-position ready to shot but hindered by the inner pressure of the device. The automatic closing of the device is:

The first inventions-advantage.

Figure 2 shows the forces produced by the inner and the outer pressure bringed into equilibrium by the membranes elastic force.

Also when the dispositive is closed, that is the ball rest in the membrane. This is due because the inner pressure in bigger as the outer pressure. Then the ball press against the membrane with a force that is proportional to the difference of the inner and outer pressures, thus being in static balance whit the elastic force of the distorted membrane, b) The closed device

Now a question arises: What happens if one or the other or both of the inner and outer pressures changes? If the resulting Force of both pressures acting against the membrane changes, the force produced by the membrane will also change as well and exactly in the same amount of force produced trough the pressure-change. And that is only possible if the elastic membrane changes its shape and this result in a ball displacement. And this is the:

The second advantage: Therefore if the difference of pressures changes, the ball will be displaced in a certain amount proportional to the mentioned difference of pressure, as a result the displacements magnitude give us information about the pressures difference also called differential-pressure. This capability of measuring the differential-pressure or using the ball displacement for other purposes is also a second advantage, in addition of the automatic closing or first advantage of our invention.

In order to illustrate the displacement of the ball and the shape changing of the elastic, and the ball involving, membrane, we have drawn an experiment in image Figure 5 where we show a closed container whit our device as a closed bottle in three different cases, case a) the bottle number 1 is opened and have therefore the same pressure as the chamber pressure p(a) whereas the bottles 2 and 3 have different pressures between them and between the pressure of bottle 1. During such an experiment we observe that really the ball position in bottle 3 shows a displacement "dist" from the ball position in bottle 2.

When the device is closed and we use an elastic membrane it is possible to open the closed device through the membrane or direct trough the ball

The third and fourth advantage: Where already mentioned in page 1

The third acting trough the opening and the fourth trough the membrane as shown in

Figure 4 where we observe the pushing finger opening the device in a) pushing the membrane and in b) direct trough the ball in order to open up the device.

The fifth advantage is the easy way to handle measures and opening the device through the membranes' device: The easy way of handling the opening of the device and taking measures of the displacement of the ball is also illustrated in Figure 4, but that's not all, this ease handling allows also the use of sensors, or on-of devices, direct attached to the membrane as shown in Figure 5.

The easy opening of the closed device and the easy flow control of it, is:

The third advantage of the invention

That there is such an easy way to open our devise allows, among other things, the use of a comfortable openings mechanisms like the pneumatic pump shown in Figure 6, there we can observe that when we actions the pedal 15, the pneumatic pump comes into functions and finally, through a series of pneumatic and mechanical elements (12, 10,, 9, 7, 8) the pneumatic force pushes the membrane 1 (Section A-A) and the membrane pushes the ball 2 through the chock or wedge 3, thus producing the opening of the device. The design may look complicated; there are sure many ways to solve this problem in a simpler way. It is not the design itself which is important; important is the fact that there is the possibility to:

Open the devise whit a pneumatic pump.

And also our device make it possible to measure the inner pressure of a system, let's say we want to monitor the pressure in a steam boiler, also using a pneumatic pump. For that purpose we have developed a very simple device shown in Figure 17.

There the different ball positions in cases a) and b) tell us that the case b) have the bigger value. There we have fix-attached a pneumatic pump, part 5, which has a ring form or torus form, direct to the membrane. As we can observe the ball presses the membrane in an amount proportional to the inner pressure, and the membrane press down the elastic pneumatic torus and the displaced gas or liquid amount presses the mercury column which riches in case a) the value 3 and in case b) the value 13.

An important remark: the movements of the ball and or membrane are detectable whit many means and in many ways, now we are talking about the pneumatic pump, but we can utilize other means like optical, electrical, electronic, and many other means and ways. The same remark in appropriate in case we decide to move the membrane or the ball in order to open or manipulate the flow or whatever.

The sixth advantage of the invention concerns the closing force of the ball against the membrane. In Figure 7 we have drawn in parts a), b) and c), three different kind of balls which are a) the hardest b) the medium hard, and c) the softest, for the same pressure conditions. As we can observe, in the lower-right part of the softest one of the balls is the one whit the biggest contact surface of the three balls. That means also that the softer the ball is, the strong the closing force, that means that in order to open the device we have to apply a stronger force as in harder balls. This condition can be useful when having our device in WC outflow valves and having the wish to obtain the best possible watertight. The Venturi Omega Balloons: if we put a ball into a balloon an inflate it, the balloon is exactly in the same circumstances we have been described all trough this document. The balloon is, in this case, one more of these situations where the balloons are as elastic containers to see.

Play Instructions for the Venturi Omega Balloons.

Whit the inflated balloon and the ball inside it, we don't need to make a knot, which is mostly a definitive tide. Our Venturi Omega Balloons are very funny to play whit and we have discovered several novelties.

One of the novelties is the balloon whit an obstructed outflow as shows in Figure 15, the instructions here below, and this drawing belongs to the play instructions that we plan to sell whit the Venturi Omega Balloons

Your Venturi Omega Balloon is delivered whit the appropriated ball placed inside the balloon.

You can inflated the balloon as usually, and kipping the nozzle closed, you can turn the nozzle to the lower part, so the ball drops and comes into the nearest area of the nozzle. Now you can lose the outlet or nozzle and you will observe that maybe a lithe amount of pressurized air comes out of the balloon through the outlet, but immediately the flow will be automatically closed because of the Venturi Effect. Now you can turn the balloon to different positions, even the inverse position, that is the nozzle to the top. And then you can start playing perhaps throwing the balloon to a playing mate and your playing mate throwing the balloon back to you. Whit some strikes, or when the balloon strikes the floor, some air will be loosen but the flow will automatically stopped, because of the Venturi effect.

If you want a better or a more stable closing, you don't need to make a knot to the balloons nozzle (that would be an almost definitely closing). You only have to push the ball into the nozzle and if you want to pump out the balloon and save the balloon for the next play, you shall slide the ball back to the wider side of the balloon as shown in Figure 15.

The cage: There are some requirements we shall keep in mind in order to have an optimal operation of our balloons, since they shall automatically close.

The Bernoulli equation and the Venturi effect only occur when, first, there is a stream, and second, when the ball is in this stream which, because of the device's shape, the stream accelerate und induce a pressure-drop.

The pressure-drop attracts the free swimming ball to the balloon's surface where the pressure is lower. And again the coming nearer of the ball produce an accelerating of the stream and a new pressure-drop an so on.A split-second before the impact of the ball ^•against the balloon's wall, the ball reaches its peak-speed and the pressure in-between ball and wall drops to a minimum near vacuum. That is how the automatically close happens.

In an inflated balloon the stream arises in case of leakage, there remains however the second condition the ball has to be in the influence area, were the flow accelerates. There is also the need to restrict the space were the ball may stay.

If we now go back to the Figure 4 we can observe that there appears a cage, a sort of barred enclosure has been drawn, and is numbered as item or element number 6.

In the Figure 20 we have introduce a smaller balloon, element 3, into the main balloon, element 1 , the both of them will be stick or glued together. The smaller balloon has, as we can notice, five skylights or holes, marked whit number 4 having a smaller diameter as the ball's-diameter , thus the ball keeps inside it.

In order to reinforce the closing force of the Venturi effect , in Figure 21 we have introduce an elastic cage, item number 3 which has a space dimension smaller than the ball^'s one, thus increasing the closing force.

For the same purpose as in preceding case, Figure 21 we have put a cage number 3. This cage is smaller so that the ball will be pushed to the balloon^'s nozzle thus adding elastic force to the Venturi ^'s effect closing force,

in Figure 22 we show a check valve design developed by myself.

In Figure 23 we show a balloons device which acts as a check-valve. The balloon's nozzle has a hollow part to lodge the ball. In order to keep the ball always in the influence area of the Venturi-effect we have placed a sieve 3 that let the flow pass in both directions, but that hinders the ball to go any further.

WC Omega rinsing-device: Now changing to another feature of the device, the WC Omega rinsing-device, we have developed recently is a brand new WC down rinsing device whit only a few components and having a pumping effect, the Venturi effect, to pump some cleaning or deodorants liquids into the WC:

In Figure 14 we see a WC down rinsing Tube, the elements are:

1 The upper, small (about 2 Lts.) container

1a The water supply tube

2 The diffuser or upper element of the main-container or principal reservoir

3 The main's reservoir tube

4 The Venturi-tube

5 The under stopper

6 The upper stopper 7 The Venturi's liquid-intake

8a The pull-down-ring

8b The upper connecting cord

8c The between stoppers cord, or union cord

A propos this design showed in Figure 14 is important to remark that there is no Level- Control-Devise (Valve or whatever), nor outlet-pipe. They are only a pair of united stoppers which provide the opening and closing of the principal water reservoir 3, which allows only a smaller discharge, for liquids, or also the adding of the water amount of the smaller reservoir and thus get the full amount of water for solid and liquid throwing away.

The WC down rinsing device works in the following way: Figure 16

- In sequence a) the stopper 5 closes the device, while the upper stopper 6 remains in the open position

- In sequence b) both stoppers 5 and 6 are in the open position thus letting the water contents of both containers 1 and 3 flow into the WC

- In sequence c) the upper-stopper 6 closes the small container 1 , whereas the under- stopper 5 opens the outflow, letting the small-amount of water, contained in the under-tank to pour-down or rinse into the WC

We can choice to let the total up-stored amount of water down-flow, sequence b) or only the under-tank-amount to rinse-down to the WC, sequence c)

We may use another mechanism to lower or sink both of the stoppers as we can see in Figure 19. Here the rising of the stoppers will be done by means of a pneumatic piston, or element 8, in that Figure 19, where the pressurized air will be pumped into the air-chamber through the air-injection over the intake pipe 7. While the Venturi pump effect can be used over the lower intake pipe 7b to slip in some liquids like deodorants, disinfectant and, who knows, rainwater or soapy-water, in case we want or need to bring an extra spar of tap water. Because when we only use the smaller amount of water for down rinse only liquids we are already economizing water let say using 4 liters for liquid rinse and 7 liters for solids in all design-models explained in the above and next lines.

A different alternative will be shown in Figure 18; here we make use of the easy opening feature of the device.

The elements of this image are:

1 Small tank and water-supply entrance

2 Diffuser

3 Main-tube-container

4 Venturi

5 Under-stopper

6 Upper-stopper

7 Venturi's -pump- intake

8 Stopper^'s connecting bar

9 Bar^'s sliding guide

10 Bar^'s guide holder

11 Pushing element, to easy opening of the device

In Figure 18 sequence a) we observe that the under stopper 5 is in the close position and the upper stopper is opened. This is the start position, were both containers 1 and 3 will be filled or are already full and ready for a down-rinse.

Sequence b) shows that both stoppers 5 and 6 are in a opened position, thus letting the whole stored water outflow into the WC. This is the biggest amount of rinse-water we can pure into the WC and is thought for solid and liquid waste. Sequence c) shows that the under-stopper is opened while the upper-stopper is closed. This situation allows only the outflow of a minor amount, and is thought to be used whit liquid waste.

Of course we may make use of the other easy opening feature: the opening trough the nozzle of the Venturi, and because we have already make an example of it in, among other places, in Figure 4 and Figure 8: we may also, this time, spare us the appropriate drawing and nevertheless we are entitled to claim the ownership of the invention and design as our intellectual property.

Whit this last sentence the inventions description is concluded never the less we would like to refer to a couple of design we bring now in the next paragraph of this description as paragraph 3.1 - Devices and designs.

3.1 - Devices prototypes and designs:

Using the Venturi-Omega-devise^'s characteristics we have develop a series of practical devices among others we have the following items:

^*On-Off-Device: Figure 5

*Pedal-tap or pneumatic-tap: Figure 6

*Atmospheric-pressure-measuring-instrument or Barometer: Figure 9

*Airplane-velocity-Meter or Wind-Velocity-Meter: Figures 10 and 11

*Level-controller: Figure 12

^*Safety-valve: Figures 13 a), 13 a), b), 13 a), c)

*The Venturi Omega Balloons Figures 8, 20. 21 , and 23

*The Venturi Omega WC-down-rinse-tube Figures 14, 15, 16 and 18

The difference between the till yet used tank devices is that the reservoir or tank is, in our new device, not an open container but a closed one It is also remarkable in the named Figures, that there are only one moving assembly made out of two spheres, or closing elements, united by means of a chain, rope and a bar (element 7 in Figure 18) or whatever union-element, plus a hoist- or jack-equipment The jack or hoist equipment is made out of element 8a and 8b in Figure 15 while in Figure 16 is build up of elements7, 8 and 9 and in Figure 18 is constituted of elements: 8, 9, 10 and 11

- The using of our device in a WC's down rinsing Tube

5. - The drawings

Figure 1 represents the Venturi-Omega-device, the elements are 1 : membrane, 2: ball and 3 stay for aggregate, in part a) we can observe the stream-lines while in part b) we can see the stream-forces f(s) which impel the ball 2 against the membrane 1

Figure 2 In the upper part we find our ball whit different vectors:

In a) and c) we have the vectors which represent the local, at every point, inner pressure While c) represent the same condition as a) since they are in a) symmetrical vectors whit respect to the horizontal-middle-axle that, when added, disappear as shown in b) The result of adding b) and c) is illustrate in d) where the vertical components are symmetrically opposed whit respect to the horizontal-middle-axle can be taken away as exposed in e)

In e) we split the sphere and observe on the left side of the vertical-middle-axle the added vectors acting upon the surface of the sphere. The on the surface acting vectors may be substituted by the resulting vector acting in the middle of the half-sphere and as the resulting force "Res. r(1) - r(2) " originated by the pressure acting upon the surface of the entire sphere.

This force pushes over the entire sphere upon the membrane and changes the shape of the same (membrane) thus causing the resulting force Res T (membr.)

This all means that the inner and outer pressure p(1) and p(2) acting upon the sphere produce a resulting force which deforms the membrane and cause a displacement of the sphere; The deformation of the elastic membrane produce also a resulting force which neutralize the pressures force bringing the entire system to rest or to equilibrium.

In one sentence: The forces produced by the differential-pressures are equilibrated whit the force produced by the membrane's displacement.

Figure 3 This drawing illustrates the membrane's displacement due to different pressures differences:

4 is a closed container which holds three venturi-devices 1 , 2, and 3. The pressures-ratio p(med)/p(a)in part b) is smaller than the pressures-ratio p(max)/p(a) in part c), therefore the ball position get further into the membrane as we can observe trough the space "dist". Figure 4 Shown the easy opening of the device trough the membrane 4 or direct trough the ball 3

Figure 5 shows how the displacement of the ball con be used on an on-of device

Figure 6 shows how trough the easy-opening feature can we activate a tap as "no hands" tap whit pedal 15 and pneumatic mechanism

Figure 7 is a sketch that sows a hard ball in a) a medium-hard ball in b) and a soft-ball in c). Here we find out that the softer the ball, the bigger the closing force: an important feature of our device. For instance in a WC outflow valve.

Figure 8 represent a liquid-soap (item 5) dispatcher. The elements are: 1 an inflated balloon or another vessel containing liquid soap and a gas (air), 2 ball, 3 bushing, 4 hollow-tube, 5 soapy solution, a) in the closed- and b the opened position

Figure 9 represents an atmospheric-pressure-monitoring-device or barometer. The elements are 1 : membrane, 2: ball, 3: closed container, 4: union elements, 5: frame, 6: guide, 7: tooted rod, 8: holder, 9: pinion, 10: pointer, 1 1 graduated board.

The atmospheric-pressure pa2) is smaller than pal) the pointer turns to the lower pressure side of the measures-panel or graduated board. Figure 9 is also a barometer that uses the differential-pressure-measures feature of the Venturi elastic dynamic device. The device inner-pressure is a constant value sequence b) show what happens if the atmospheric-pressure drops from pressure in a) to pressure in b). The pressure-drop causes a ball-displacement Δ that we can determinate (measures) whit one of the many available messing methods, like optical, analog, digital, electronic, pneumatic and so on.

Figures 10 and 11 put on view an airplane velocity-monitoring-device which uses the differential-pressure-feature and is similar to the Pitot-tube and the Prandtl tube

In this Figures 10 and 11 we notice that the flow pushes the ball 2 against the membrane

1 whit the total pressure pt and that the stream passes tangential to the orifices 3 producing inside the container 7 the static pressure ps.

The displacement Δ is also proportional to the dynamic pressure and therefore

proportional to the flow-velocity.

All of them can be expressed by means of the Bernoulli's equation.

We ought to build a devise whit about the same dimensions of the existing Prandtl tubes and bring it to a wind-channel in order to calibrate the device. This means that if we blow -wind against our device whit a know speed and notice this value and the displacements- value, after a few of such a measures we get a scale similar to the scale which appears inside o our device.

In our case we don't need a transducer since our devise itself is a transducer which replaces kinetic- and static-energy into elastic- or shape-changing-energy of the membrane. Δ is also proportional to the velocity value.

Figure 12 Shows a level-control-device: in part a) the device is open the wather intake comes from below through the membrane 1 passing the cage 1 and entering the tube 3 trough the opening 3a and passing the top of the tube pours out into the tank 7. 5 is a closed body in donut or torus shape which floats and raises the tube 3, which is a piston sliding up guided by the tube 4, which is a piston's shell or piston's sleeve till it comes to the final position in b) where the opening 3a is covered by tube 4.

By then the sphere 2, which also floats, has closed the stream, in a hermetic way

Figure 13 represents a safety-valve:

In sequence a) the inner pressure p(1) has not, until now, reached the critical or opening pressure p(2) and therefore the valve is closed and the fluid may not out pouring, since the switch 5 has not yet been activated by the button 6. So the pressure can continuing claiming till it reached the critical or limit inner pressure p(1 )

Sequence b) is the halfway between sequence a) and sequence c) here the pushbutton 6 has been activating and the switch started now the action of the three servomotors 7, 8 and 9

In sequence c) the activated servomotors had taken the pushing pistons 9 out of their pistons-guide 8 and the push-pistons have pushed the membrane 1 into the opened positions so the valve is open and the not wished-, maybe dangerous-pressure will be not reached since by opened valve the pressure drops.

The items or elements are: 1 membrane, 2 ball, 3 switch-holder 4^"tubular-frame, 5 switch,

6 switch ^'s-button, 7 servomotor-holder, 8 servomotor, 9 pusher

Figure 14 shows our WC down rinsing Tube, typical model. The explanation of this and the following WC-Tube figures start in page 8, linel 17 and ends in page 1 1 , line 11

Figure 15 shows the way to get a stable closing of our Venturi-Omega-Balloon the precondition is to have the right ball^'s weight, smoothness and diameter to realize the reliably balloon^'s closing.

Figure 16 shows the WC down rinsing device working way as explained under page 9 from line 10 till page 9 line 20 Figure 7 shows how can we measure the inner-pressure p(2) through a pneumatic mechanism and monitoring through a mercury-column.

Figure 18 shows another mechanism to lower or sink both of the stoppers, as explained from page 9, line 21 till page 10, line 13

Figure 19 shows another mechanism to lower or sink both of the stoppers as explained from page 9, line 21 till page 10, line 17

Figure 20 shows a balloon whit a minor or secondary perforated balloon which contains the ball inside of it and serves as a cage. There we have also two solutions: the separated balloon or a cage out of the same material as the principal balloon and being a one piece whit the outer balloon. Here the cage is a smaller balloon item 3, whit some holes, element 4, smaller than the ball, item 2.

Figure 21 the cage is part of the balloon and was explained in page 8, line 6 till page 8, line 8.

Figure 22 is a special balloon^'s check-valve to increase the Venturi^'s closing effect as written in page 9, line 9

Figure 23 is the drawing of a special balloon 1 whit a special sieve 3 to hinder the ball 2 from going outside of the Venturi^'s effect effective space, as explained in page 8, line 10 till page 9, line 13. Figure 23 shows a Venturi-Omega-Balloon the sequence a) illustrate the closed balloon while b) put on view the inflating moment. The drawing-elements are:

1 balloon

2 ball

3 grid

4 cavity

The special balloon 1 which has a special nozzle whit a cavity 4 that lodges the ball 2 has an inserted grid to hinder the ball from going outside the influence-area of the venturi effect. This grid is fluid permeable thus making the inflation possible. In order to deflate one must slip the ball aside so the flow may out coming.

6. - The inherent advantages of the invention are:

- The self-closing effect

- The membrane displacement according to differential-pressures variations -

- The flow regulation through the outlet or through the membrane

- The increasing closing force of the device whit softer balls

- While the special advantages of the many designs were already discussed, we would like now to mention the benefits of the Venturi Omega WC-down-rinse-device

There are only two moving elements the upper and the under stopper plus the necessary union elements and the hoist mechanism for the movement of the stoppers. There is no level-control-device, nor an upper-level-outflow mechanism. Besides the WC-down-rinse- devise developed by me can save water when using it as a only liquid down-rinse-devise and has beyond of this a special intake pump whit no moving parts or a Venturi-pump, made out of two elements the Venturi-tube 4 and the intake pipe 7 (look up Figures 14, 16, and 19).

7- The way to obtain the best results

In order to get the self-closing effect of the Venturi effect you must have enough flow and the ball shall be inside the influence area of the accelerating stream. Although you may reinforce this effect, look up Figures 22 and 23.

Claims

Claim 1. - : I claim the Venturi Omega device, which is build out of two principal elements: the membrane 1 and the ball 2 Figures 1 and 2 one or more supplemental items the so called aggregate (part 3 in Figure 2).

Its principal features are:

a) The self-closing-effect or Venturi-effect. In order to correctly obtain the Venturi-effect there are two compulsory conditions to be fulfilled: a1 ) there shall be enough flow and a2) the ball shall be in the influence area of the Venturi-effect. Where the Venturi-effect is produced by the acceleration of the flow and the device is in the open position

b) The displacement of the ball and or the membrane caused by the ratio-change of the inner-pressure to the outer-pressure of the device, as shown in Figure 3 whereby the increasing of the inner- to outer- pressure between case b) and case c) produces a displacement "dist" of the ball and membrane

c) The easy-opening of the device as shown at Figure 4

d) The increasing closing-force produced by the increasing of the softness of the ball as shown at Figure 7

In a Venturi-Omega-design we may use one or more of the enumerated, from a) to d), features

Claim 2. - : I claim the Venturi Omega devices which make use of both of the two principal features of the Venturi Omega device namely: a) The self-closing-effect and b) The displacement of the ball and or the membrane. In special: I claim the design of the safety- valve shown in Figure 13 and explained in chapter: 5. - The drawings (from page 16 line 5 till page 16, line 18)

Claim 3. - : I claim the Venturi Omega devices which make use of the automatic closing of the Venturi Omega device in special I claim the design of the Venturi Omega Balloons as explained in The Venturi Omega Balloons, starting in page 7 and the following Figures 8, 15, 20. 21 and 22 and their explanation in chapter 5. - The drawings

I claim the balloon^'s play instructions included in The Venturi Omega Balloons, starting in page 6, line 5 and ending in page 8, line 14.

I claim the liquid-soap-dispatcher shown in Figure 8 explanation in chapter 5. -

I claim the easy closing of the inflated balloons and the easy deflating of the balloons as explained in Claim 1

I also claim the balloons-check-valve as shown in Figure 22 and explained in the drawings chapter: 5. - The drawings

I claim the balloons-cage which restrain the place where the ball will stay to the influence area of the Venturi-effect, as shown in Figures 20, 21 , 22, 23

I also claim the special cage shown in Figure 20 where a secondary smaller balloon whit 5 hatches that les pass the flow but don^'t let pass the ball, explained in chapter 5. - The drawings.

Claim 4. - : I claim the self-closing-WC-valve as shown in Figures 14, 16, 18 and 19 which are explained in chapter 5.-

Claim 5. - : I claim the easy-closing-feature of the device and the design of the device shown in Figure 6 and the respective explanation on in page 5, from line 12 till line 24 and in chapter 5.-

Claim 6. - : I claim the use of the ball- and or membrane-displacement to release a further action as shown in Figures 5 and explained in page 5, line 5 till line 7 and also in Chapter 5. -

Claim 7. - : I claim the capability of the Venturi Omega Device to carry differential- measures on as shown in following Figures 17, 9, 10 and 11 and their explanation in chapter 5. Now I claim the presented designs and devices

Claim 8. - : I Claim the barometer presented in Figure 9 which consist of the following elements:

1 Membrane

2 Ball or closing element

3 Hermetic container at constant internal-pressure (pi)

4 Connecting elements

5 Housing

6 Bushing

7 Rod

8 Push-bar

9 Pinion

10 Indicator

The measure's solutions showed above is only an example of the manifold of possible measure's ways available like optic, electronic, etcetera.

When the atmospheric-pressure changes, the indicator will turn to one side

of the panel.

Claim 9. - : I Claim the airplane's speed-measuring-instrument presented in Figures 10 and 11 which consist of the following elements: (numbered in Figure 10)

1 Membrane

2 Ball

3 Borings

4 Push-bar

5 Pinion

6 Pointing-device 7 Bushing

In Figure 19 we observe in a) a wind-speed lower than the wind-speed in b) causing a displacement of the ball Δ which is measurable by one of the many measures-way available.

The ground or fundamental idea, in which the present device lies, is to be searched in the Pitot-tube and in the Prandtl-tube. In our device the total pressure is proportional to the flow acting on the ball 2 and to the inner-pressure of the chamber which is a closed container whit a series of orifices or borings 3, where the inner-pressure of this chamber is an induced pressure, proportional to the static pressure.

The differential-pressure of these two pressures (Total- minus static-pressure) is analog to the flow velocity surrounding our device.

If we make measures of the membrane displacement of well-know flow-speeds, we will obtain a calibrated airplane's-speedometer.

Our Figures 10 and 11 do not reflect the shape of the instrument, which will maybe nearer to ½ inch diameter and about 10 inches long, in cylindrical profile.

Claim 10. - I claim the "no hands" tap showed in Figure 6, which consist of the following elements:

1 Membrane

2 Ball

3 Wedge

4 Cage

5 Connecting-elements

6 Connection-thread

7 Bushing

8 Pushing-bar Pneumatic-chamber

10 Housing

11 Connecting-tube

12 Pipe

13 Support-disc

14 Base-plate

15 Pedal

16 Big-chamber

17 Pivot

When acting the pedal 16 the chamber's gas will be impelled from the bigger- to the smaller-chamber which will be inflated and pushes the membrane and the wedge 3 which moves the ball to the inner-part of the device in cage's-direction thus opening the tap. Claim 11. - I claim the Pressure-monitoring-device showed in Figure 17 which consist of following elements;

1 Membrane

2 Ball

3 Frame

4 Connecting element

5 Rings-chamber

6 Piston

7 Reading-position

8 Connecting-pipe

9 Frame

10 Air-tube

11 Bracket 12 Mercury- column

When the inner-pressure increases, the ball and the membrane will be displaced thus pressing the rings-chamber 5 and displacing the piston 6 against the mercury and therefore letting the mercury-column claim upwards.

Claim 12. - I claim the on-off-device shown in Figure 5 which is made up of the following components:

1 Membrane

2 Ball

3 Rod

4 Screw

5 Bracket

6 Switch

8 Press-button

In b) the pressure^'s-value is bigger than the pressure in a), that produces a ball and membrane displacement which causes the pressing of the push-button 8 and activates the switch changing it from the off to the on position.

Claim 13. - I claim the safety-valve shown in Figure 3 whit following elements:

1 Membrane

2 Ball

3 Switch-holder

4 Frame

5 Switch

6 on-off press-button

7 Bushing-support

8 Bushing 9 Push-bar

The difference of pressures between a) and c) produces a ball and membrane

displacement "D". In c) the membrane 1 pushes the on-off-button 6 which bring the servomotors into action, it means the push-bar pushes the membrane and the ball back thus opening the valve and producing a pressure-drop inside the valve till the self-closing-effect closes the valve.

It is remarkable that all the elements of the control-mechanism lay outside the stream which brings many advantages as well for the controlling-elements as also to the cleanness of the fluid.

Like avoiding corrosion of the acting-elements avoiding soil and contamination of the fluids, this can be very useful in the pharmaceutical- and food-industries

Claim 14. - I claim the Top-level-control-valve for open containers or tanks as shown in Figure 20 whit following components

1 membrane

1a integrated-cage

2 ball

3 tank-filling-tube

3a tube's intake-orifice

4 bushing

5 floating-hollow-device (torus- or donuts-shape)

6 union-element

7 tank

8 and 9 union to pipe

In a) the top level has not been reached and the valves is open continuing the tank-filling operation. In b) the top level has jet been reached and the ball closed the valve because of the venturi-effect reinforced whit the floating force of the ball when the ball is lighter as the fluid.

The integrated cage is a part of the membrane, fact that we want to underline because this is the best way to keep the ball in the influence area of the Venturi-effect in balloons and other devices

When the cage is about the same size as the ball, the elastic cage acts as a spring in a check-valve reinforcing the closing effect, therefore I claim it separated in claim 16 here below:

Claim 15. - I claim the integrated cage in the membrane of the Venturi-device in general. Figure 12 and Figure20 illustrate this in particular: 1 a in Figure 12 is the claimed integrated cage; while element 3 is the claimed integrated cage in Figure 20. The cage muss not be necessarily build the same element as the membrane, as in Figure 21 , they can be two separated items as illustrated in Figure 20.

Claim 16.- 1 claim the integrated cage in the membrane as in Claim 15. -, but in smaller shape-dimensions in order to reinforce the Venturi effect as shown in Figure 21

Claim17. - I claim the self-closing-device-design as shown in the Figure 23 which shows a Venturi-Omega-Balloon the sequence a) illustrate the closed balloon while b) put on view the inflating moment. The drawing-elements are:

1 balloon

2 ball

3 grid

4 cavity

The special balloon 1 which has a special nozzle whit a cavity 4 that lodges the ball 2 has an inserted grid to hinder the ball from going outside the influence-area of the venturi effect. This grid is fluid permeable thus making the inflation possible. In order to deflate one must slip the ball aside so the flow may out coming..

Claim 18. - I claim the instructions and drawing in order to obtain a firm, but reversible, closing of the balloons. In case we do not have a cage and want to reuse the balloon after deflection and keep it for later on. This kind of closing is shown in Figure 15

I claim also the right dimensions of the ball^'s diameter, weight and smoothness, that I have find out, in order to have a reliable and easy balloon^'s closing

the elements are:

1 balloon (membrane)

2 ball

After having inflated the balloon, we can now push the special ball 2 into the balloon's nozzle 1 by closing this way we get a firm close and still we can deflate the balloon and inflating it again many times for reuse again the balloon for play or decoration.

Claim 19. - 1 claim the Ventu -effect reinforcing valve illustrated by an example in Figure 22. The valve will be mounted in the balloon^'s nozzle whit element 4 facing the balloons- nozzles out-side.

Claim 20. - I claim the Venturi omega balloons play instructions, that lie from page 6, line 5, till page 8, line 13

Claim 21. - 1 claim the self-closing-device shown in Figure 20, there is to observe., that a smaller-balloon whit orifices smaller than the ball lies inside the principal balloon, so the ball cannot passes through the orifices but the flow passes in both directions, at the going out direction the Venturi-effect arises and close the balloon. Look up chapter 5. - to.

Claim 20. - 1 claim the WC Tank whit the Venturi-self-closing-valve and the necessary provisions in order to achieve correctly the closing of the devise. In Figure 14 the smaller or auxiliary tank 7 provides that there will be enough flow, at the closing moment of the principal tank 3, and the position of the auxiliary-tank 7 hinder the ball 2 from going out of the influence-zone of the Venturi-effect. Look up chapter 5. - .

Claim 21 . - I claim the two containers system that allows the two different water-amount that outflow, the smaller discharge will be used to rinse only liquids. In Figures 14, 16, 18 and 19 the water-charge of the upper-vessel provides the second additional loading necessary to take the solids away

Claim 22. - : I Claim the balloon's check-valve, used to reinforce the Venturi effect and exposed in Figure 23 which consist of the following elements:

1 Ball

2 Spring-holder

3 Case

4 Gasket

5 Spring

The check-valve will be push into the balloons-nozzle putting first, at the balloon^'s side of the nozzle, the spring-holder, so that the gasket side will stay in the final-part of the nozzle. When inflating the balloon the gas-pressure will press the spring and displacing the ball to the inner-part of the balloon and letting the gas penetrate to the balloon. When the gas pressure stops the ball will be impelled towards the gasket by the Venturi-effect, reinforced whit the spring force.

Claim 23. - 1 claim all the devices designed by me and showed in every one of the drawings showed within the present patent application as well as their explanation. The solutions showed in these drawings and designs are proposed as examples of a particular problem's solution and therefore I am entitle to claim some other possible solutions to the same problem using other items, assemblies and shapes that lead to the same solution. Per instance the mechanical-, optical-, electronic-, etcetera- measure of the ball^'s displacement.
