However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in order not to obscure the present invention.

U.S. Patent Application No. 13/180,985, entitled DENTAL TREATMENT APPARATUS AND METHOD, commonly owned by the inventors of the present invention, discloses a device for supplying pressurized fluid, which is cited by its The entire content is incorporated here. Referring now to FIGS. 1A and 1B , which depict a device 10 suitable for supplying pressurized fluid, respectively, in its empty state and when filled with operating material, as described in commonly-owned U.S. Patent No. described in detail in Application No. 13/180,985. The device 10 comprises a container 12 divided into a first compartment 12A and a second compartment 12B by a partition 12C adapted to allow liquid to pass freely through the partition. The first compartment is adapted to contain a liquid, the second compartment is adapted to receive a first active material and a second active material, and the rear cap is adapted to close a first end of the container, wherein the first end is separated from the second active material. The compartment is closer and includes operational controls for controlling the dispensing of pressurized liquid from the container. The operation control device is mounted on the front cover closing the second end of the container, wherein the first active material and the second active material are adapted to generate a first pressure in a chemical reaction by an effervescent process, and this operation The control means is adapted to reduce the first pressure to the second pressure. The second pressure remains constant regardless of the orientation of the container relative to the direction of gravity. According to a further embodiment of the invention, said device comprises a dispensing tube connected at a first end to said operation control device for receiving pressurized liquid at a second pressure and adapted to transfer said pressurized The liquid is dispensed through the dispensing orifice. The device further comprises a pulsating mechanism for supplying the pressurized liquid to the dispensing orifice in at least one pulse. The number of said pulses within a time interval is controllable.

Reference is now made to Figures 2A, 2B and 2C which illustrate the device 10 at three different angles of inclination and the respective configurations of these feed tubes 17 due to a counterweight 17B mounted at the distal end of the feed tubes , to ensure that the feed tube remains submerged in the liquid in the device 10, as described in detail in US Application Serial No. 13/180,985, commonly owned by the inventors of the present invention. This approach ensures that pressurized fluid is supplied to the regulator and on/off assembly 14 (FIG. 1A) or pressure regulating device 14A until the fluid in the device 10 is substantially depleted.

Referring now to FIG. 3A , which schematically depicts a partial cross-sectional view of the end of a distribution tube 310 as described in detail in US Application Serial No. 13/180,985, commonly owned by the inventors of the present invention. The distribution pipe 310 may have mounted therein a spatial helical element 312 configured as a long pitch thread or worm having a longitudinal axis coincident with the longitudinal axis of the inner bore 313 of the distribution pipe 310 and having an alignment with the bore 313. The inner diameter smoothly mates with the outer diameter thereby allowing smooth rotation of the helical element 312 in the inner bore 313 . According to an embodiment of the present invention, the helical element 312 may have an auxiliary shaft 315 fabricated at the end of the helical element 312 .

Pressurized liquid entering the dispensing tube 310 through the bore 313 and exiting through the dispensing outlet orifice 316 flows through the helical element 312 and causes the pressurized fluid to spin rapidly about the axis of the helical element 312 . As a result, the pressurized fluid passes through the knife segment 317 of the helical element 312 and near the inner end of the dispensing outlet orifice 316 , creating intermittent intervals of pressurized fluid flow through the orifice 316 . The number of spaces in the pressurized fluid flow is substantially equal to twice the rotational speed of the helical element 312 .

Reference is now made to FIG. 3B , which is a partial cross-sectional side view of a hand tool 320 as described in detail in US Application Serial No. 13/180,985, commonly owned by the inventors of the present invention. The hand tool 320 may include an elongated bore 322 allowing the supply of pressurized liquid and/or pressurized gas inside the hand tool along its longitudinal dimension. Bore 322 may be formed to feed pressurized fluid into annular space 324 in a tangential manner, thereby causing rapid rotational motion of ball 326 in the plane of FIG. 3B . The rapid rotational motion of the ball 326 may cause two-dimensional compound vibrations of the hand tool 320 . Accordingly, the jet of pressurized fluid emerging from the outlet orifice 325 flows in a pulsed fashion.

Reference is now made to FIG. 3C , which is a schematic partial cross-sectional side view of a hand tool 330 as described in detail in US Application Serial No. 13/180,985, commonly owned by the inventors of the present invention. Pressurized fluid flowing through bore 332 and through formed fluid path 334 causes wheel 336 in the path of the pressurized fluid to fluid bore 337 to turn. Thereby, intermittent flow of pressurized fluid is induced, exhibiting a pulsed flow of pressurized jets through outlet orifice 337 .

Reference is now made to FIGS. 4A and 4B , which are schematic partial cross-sectional top and side views of a hand tool 400 for supplying pressurized fluid while vibrating, as in U.S. Application Serial No. 13/180,985, commonly owned by the inventors of the present invention. described in detail. The hand tool 400 may include an elongated bore 402 allowing the supply of pressurized liquid and/or pressurized gas inside the hand tool along its longitudinal dimension. The pressurized fluid bore 402 may terminate in a tapered fluid path 404 which may be formed for tangentially supplying pressurized fluid into the inscribed annular space 406 through the fluid outlet 404A. . The annulus 406 is sized to fit the ball 408 such that when the ball 408 is driven to rotate within the annulus 406, the ball is free to rotate but at the same time provides good contact between the ball 408 and the inner surface of the annulus 806. seal. The hand tool 400 still further includes an exit orifice 410 that allows jets of pressurized fluid to exit the hand tool. When pressurized fluid enters annular space 406 via bore 402 and fluid path 404, the pressurized fluid induces a swirling motion inside annular space 406 in the direction of the arrow marked in annular space 406 in FIG. 4A Turn up. Thus, the balls 408 turn in the same direction and at substantially the same speed as the vortex. Each time the ball 408 passes through the fluid outlet 404A, the ball blocks the fluid outlet for a brief moment, thereby causing intermittent flow of pressurized fluid in and out of the annular space 406 . Accordingly, the jets of pressurized fluid emerging from the outlet aperture 410 flow in pulses. Further, the rapid rotation of ball 408 induces a two-dimensional compound vibration of hand tool 400 substantially in the plane of FIG. 8A .

According to some embodiments of the invention, one dose of pressurized fluid may be delivered per push of the actuation trigger. Reference is now made to FIGS. 5A, 5B, 5C and 5D, which are schematic illustrations of a device 500 for supplying pressurized fluid that will deliver one dose of pressurized fluid per actuation of its trigger, according to an embodiment of the present invention. pressurized fluid. 5A and 5B depict the pressurized fluid device 500 in cross-sectional and partial cross-sectional isometric views, respectively, with the single-dose mechanism in a filled state. Device 500 includes a container body 502 filled with pressurized fluid and includes a dosing mechanism 511 , an actuation trigger 530 and a dispensing tube 530 . Dosing mechanism 511 may include fluid dosing tube 512 and flow restrictor 514 . The dosing tube 512 may be made of a flexible material that allows the dosing tube to be filled with pressurized fluid, or when the pressure outside the dosing tube 512 is higher than the pressure inside it, allowing the dosing tube to contract such that its cross-section forms Flat oval. The passage from feed tube 510 to metering tube 512 via flow restrictor 514 is made to allow slow flow. Flow from dosing tube 512 towards dispensing tube 520 is controlled by actuating trigger 530 such that the channel is closed when the trigger is not actuated and is clear when the trigger is actuated. During operation of device 500 , feed tube 510 may be submerged in fluid in vessel 502 . When the trigger 530 is actuated to close due to the pressure inside the container 502 , fluid fills the feed tube 510 and the fluid also fills the dosing tube 512 through the flow restrictor 514 . When the actuation trigger 530 is actuated, the end of the dosing tube 512 connected to the dispensing tube 520 faces a low pressure (approximately 1 atmosphere), so that fluid accumulated in the dosing tube is free to flow toward the dispensing tube 520 and from the dispensing tube 520 to the dispensing tube 520. Pipe 520 flows out. The pressure inside the container 502 flattens the dispensing tube 512 and prevents the dispensing tube from being rapidly refilled, as shown in Figures 5C and 5D. Once the trigger 530 is de-actuated and closed, fluid can slowly pass through the restrictor 514 into the dosing tube 512 until the dosing tube is filled again and is ready for another single dose of pressurized fluid. As described above, the amount of fluid contained in each available dose may be determined by the inner diameter of the fluid dosing tube 512 and the distance L _D from the position of the flow restrictor 514 to the actuation trigger 530 .

Reference is now made to Figures 5E and 5F, which are schematic illustrations of a device 550 for supplying pressurized fluid that delivers a dose of pressurized fluid per actuation of its trigger, according to an embodiment of the present invention. Device 550 includes a container body 552 for containing pressurized fluid, and includes feed tube 560 , dosing device 580 , trigger 570 and dispensing tube 590 . The dosing device 580 may include a cylinder 582 and a piston 584 that is slidable within the cylinder 582 with close tolerances to divide the cylinder into an inlet side and an outlet side. The spring 583 is adapted to push the piston 584 towards the entry side of the barrel 582 . Piston 584 may include one or more small holes that allow fluid to flow slowly through them. Feed tube 560 may be submerged in fluid at all times during operation, thereby feeding pressurized fluid into the inlet side of the barrel. When the trigger 570 is in the non-actuated state, the outlet side of the barrel 582 is closed. The pressurized fluid can fill the barrel 582 and the spring 583 can push the piston 584 towards the entry side of the barrel 582 . Piston 584 is able to move because fluid can flow slowly from one side of piston 584 through the orifice to the other. Pressurized fluid from the outlet side of the barrel 582 exits through the dispensing tube 590 when the trigger 570 is actuated. Thus, the pressure in the outlet side of the barrel 582 drops substantially to ambient pressure (approximately 1 atmosphere) and the piston 584 is pushed back by the force of the spring 583 due to the high pressure on the other side of the piston from the reservoir 552 To the outlet side of the barrel 582 and blocks the passage of fluid towards the distribution tube 590 . As a result, a dose of pressurized fluid is dispensed. When the trigger 570 is in the non-actuated state, the passage from the outlet side of the barrel 582 to ambient air is blocked, and the pressurized fluid can slowly refill the outlet side of the barrel 582 through the hole in the piston 584, supplying another A single dose of pressurized fluid is prepared.

Reference is now made to Figures 5G, 5I, 5H, and 5J, which depict two versions 514A, 514B, respectively, of flow restrictors in accordance with embodiments of the present invention. The restrictor 514A may initially be formed from a flat ring having a small protrusion 514C formed on its inner periphery. The restrictor 514B may initially be formed from a flat ring with a small depression 514D formed on its inner periphery. The ring may be flat, as shown in FIG. 51 , to form two adjacent parallel arms with a protrusion 514C or a depression 514D approximately at their midpoint. When the restrictor 514A is placed in the neck of the dosing tube 512, the restrictor slows the flow through the neck, but the protrusion 514C ensures a minimum flow. In a similar manner, the flow restrictor 514B may be formed from a flattened ring 514B having small indentations formed on its inner periphery to ensure slow flow of fluid through the flow restrictor 514B.

Adjustment disc 1408C may be made of a semi-flexible flat material, such as supported by hard rubber. The orifice 1408C may be made as a tapering (tapering) hole formed through the adjustment disc 1408C, with the wider opening facing the side of P1 and the smaller opening facing the adjustment disc 1408C. The other side of disk 1408C. The principle of operation of the flow regulator 1408 is explained with reference to the flow regulator 1450 of Figure 14B. The flow regulator 1450 may have: a main housing 1450A; an inlet port 1450B, facing the side where the pressure P1 inside a pressurized fluid container (not shown) spreads; and an outlet port 1450E, which may be connected to the operating mechanism and Fluid distribution tubes (neither shown). Adjustment disc 1450C may be disposed within a compartment formed by housing 1450A between inlet port 1450B and outlet port 1450E. Orifice 1450D may be made through adjustment disc 1450C and have a tapered or conical shape with the wider opening of the orifice facing the side of P1. According to some embodiments, the adjustment dial 1450C may be formed such that it is slightly raised when the adjustment dial is in place in the housing 1450A. Orifice 1450D is used to determine flow from inlet port 1450B to outlet port 1450E. As the actual area of the opening of the bore 1450D becomes larger, so does the flow rate of pressurized fluid through the opening, and vice versa. The orifice 1450D may be sized such that it does not close completely under all operating conditions. When the container of the device of the present invention is at pressure (P1) and the operating mechanism is closed, the pressure P2 at the outlet port 1450E will eventually be substantially equal to pressure 1 . When the operating structure is opened, the pressure P2 falls substantially equal to the pressure outside the device. Thus, pressure P1 , which is much greater than P2 , causes regulator disk 1450C to be flattened to some extent, and thus, orifice 1450D becomes smaller, restricting the flow of pressurized fluid through the orifice. During use of the device, as the pressure P1 gradually decreases, the pressure differential across the dial 1450C decreases linearly with this pressure, so that as the pressure P1 changes from its highest value to its lowest operating value, the orifice 1450D gradually decreases. Open and keep the flow of pressurized fluid substantially constant. It should be noted that other types of flow regulators may also be used, each of which is subject to the operating requirements of the dynamic range of pressure P1 varying between P1 _max and P1 _min and the required flow.

Having illustrated and described certain features of the invention herein, many modifications, substitutions, changes and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
