Other objects, features and advantages of the present invention will become more fully apparent from the following detailed description of the preferred embodiments, the appended claims in the accompanying drawings in which:
An embodiment of the present invention is illustrated by way of example in
Still referring to
Further, the vacuum venturi is shown located in a pipe 28. Pipe 28 is designed to deliver fluid 30 in the direction of direction arrow 32. Typically, fluid 30 is water and pipe 28 is a shower pipe. As illustrated, plug 12 is conformed to be inserted directly within pipe 28 or attached to it as hereafter disclosed and discussed. As most pipes are cylindrically shaped, according to one embodiment, plug 12 is cylindrically shaped as well and conformed to fit precisely within a pipe 28 such that no fluid escapes around plug 12 and all fluid is forced through plug 12 beginning at first opening 14. That is, fluid 30 is directed toward the first opening 14 which receives fluid 30 into vacuum venturi apparatus 10. Obviously, plug 12 may be any shape now known or hereafter developed that fits the user's preferences and needs. That is, whatever shape pipe 28 is in, plug 12 may be conformed to match and or accommodate it and still function as described herein.
As also illustrated, pipe 28 may extend beyond the length of plug 12 and second opening 16. In some cases a shower head (not shown) may be attached to pipe 28 beyond second opening 16 as may suit the purposes of the user. In any event, second opening 16 with or without the flared section 26, is the opening from which fluid 30 passes as it passes through plug 12 in the direction of direction arrow 32 as previously discussed. As such, then, fluid 30 enters first opening 14 passing through plug 12 and exits plug 12 at second opening 16 as illustrated. Obviously, when a shower head is attached to plug 12 second opening 16 is “open to the atmosphere” indirectly.
According to another aspect of the invention, the second opening 16 first diameter 20 is approximately 4.5 mm. Further, according to this aspect of the invention, the second opening 16 second diameter 22 and the single uniform diameter 24 are about 3.0 mm. Likewise, third opening 18 first diameter 21 is larger than third opening 18 second diameter 23. Further, third opening 18 second diameter 23 is smaller than whatever diameter is chosen for first opening 14. According to one aspect of the invention, third opening 18 first diameter 21 is 2.0 mm and third opening second diameter 23 is 1.5 mm and is smaller than the diameter of first opening 14. The Applicant has determined that these diameters work together to produce an extraordinary venturi effect as will be discussed more fully hereafter. In any event, variations of these particular diameters are accommodated within the scope of the present invention so long as the arrangement as discussed and disclosed herein and by way of the figures is maintained such that the second opening 16 first diameter 20 is larger than the second opening 16 second diameter 22 and the third opening 18 first diameter 21 is larger than the third opening 18 second diameter 23 and second diameter 23 is smaller than the diameter of first opening 14 and the connections of the openings are as described. Additionally, according to one aspect of the invention, the flared sections 26 of the second opening 16 and the third opening 18 are angled at about forty-five degrees as illustrated. Further the depth of the flared sections 26 is approximately five mm. Again, a variety of angles and depths are accommodated within the scope of the present invention so long as the relative dimensions and locations are maintained.
Referring now to
In operation, vacuum venturi apparatus 10 is placed in conjunction with pipe 28. This may be by means of placing plug 12 internally within pipe 28 as discussed above and providing an opening to correspond with the third opening 18 or it may be by means of connections 34 and/or 36 by which vacuum venturi 10 is placed in relation with pipe 28. However it is accomplished, once in place, the flow of fluid 30 is in the direction of direction arrow 32, as illustrated, such that fluid 30 passes first into first opening 14. First opening 14 has a single uniform diameter 24, once chosen. That is, different plugs 12 may be built with first opening of various diameters, yet once chosen, the diameter of first opening 12 does not vary in any plug 12 as shown in the figures. As the fluid 30 passes into first opening 14, Applicant has determined that a small slug of water, in the nature of approximately 0.001 ml, escapes from third opening 18. This acts as a primer that gets the venturi effect functioning. Applicant has determined that this phenomenon will not happen unless there is a “ballast effect” between the entry at first opening 14 and the exit at second opening 16. This ballast effect takes place instantaneously, in hundredths of seconds, and forms a vacuum seal right behind it. If the vacuum seal is not formed immediately behind it, the creation of the venturi effect condition fails and water leaves immediately through third opening 18 to the open atmosphere. It is by means of the combination of the first diameters 20 and 21 and the second diameters 22 and 23 that the vacuum seal is created by means of what the Applicant has identified as the ballast effect. That is to say, the ballast effect is created by the combination of the openings as described with a combination of large and small diameters.
Once the vacuum venturi effect is formed, the partial pressure gradient shifts back over in the direction of second opening 16, from which fluid exits, and the strength of the vacuum grows stronger utilizing the full force of the running stream of fluid 30 as its energy source. Applicant has determined that the vacuum venturi 10 of the present invention pulls an extremely strong −26.6 inches HG of vacuum pressure. This is unheard-of in the industry using only a flowing stream of fluid 30, e.g. water, as the energy source to produce a vacuum of this magnitude. Previously the greatest pressure Applicant was able to create was a −21.4 inches HG. This represents a more than twenty-four percent increase in the overall strength of the venturi. Further, this translates directly into an increase in the efficiency by Applicant's apparatus of about eighteen percent. This efficiency has been measured by Applicant by applying a standard test of moving water volume against time and measuring it in gallons per minute. In sum, Applicant's present invention offers a considerable advantage in improvement in the area of water conservation as a result of its increased strength in its venturi effect.
By way of further illustration of the effectiveness of the venturi effect of the present invention, attachment line 38 (shown in dotted lines) may be attached to third opening 18. When attached, attachment line 38 creates a suction on the end of the attachment line opposite not connected to third opening 18 (not shown)and thus a suction at a remote distance from third opening 18.
