Detailed description of the invention

The following description is exemplary and is not intended to limit the scope of patent claims in respect of the present invention, its use or application.

Let us now turn to the consideration of figure 2-8, which shows the gas reducer in accordance with the present invention, indicated in General position 20. Gas reducer contains a body 20 22 forming a front section 24 and the opposite side sections 26 and 28, respectively. The first indicator 30 in gas pressure in the form of analog pressure gauge in accordance with one of the forms of the present invention, mounted on the lower end of the 32 front portion of 24 corps 22. The second indicator 40 gas pressure, as well as analog pressure gauge in accordance with one of the forms of the present invention, was mounted on the upper end of the 42 the front portion of 24 corps 22. As shown on the drawings, the first indicator 30 of the gas pressure and the second indicator 40 gas pressure mainly installed vertically, one above another with staggered sideways relative to the cylinder 2 (shown by the dashed line in figure 5). It should be borne in mind that the balloon 2 is just an example of the different systems of gas supply, which can be used gas reducer 20 in accordance with the present invention. Other examples of systems of gas supply may be, for example, gas or refueling stations. As such, described here gas reducer 20 may find application in various systems of gas supply, not only in cylinders. Moreover, the "balloon" 2 should not be understood only as a cylinder of compressed gas; it can also contain liquids and other types of fluids, which is within the scope of the present invention.

As is also shown on the drawings, pen 50 adjusting the pressure is on one of the side sections of 28 corps 22. In this case, the gas reducer 20 mounted on the cylinder 2 (figure 5), so that handle 50 adjusting the pressure goes horizontally relative to the longitudinal axis of the X cylinder 2. Additional configuration handle 50 adjust the pressure with respect to the cylinder 2 are described later in more detail. In addition, handle 50 adjust the pressure in one of the forms of the present invention includes a textured outer surface for ease of use/ capture containing ribs 52 and cuts 54.

As also shown in figure 5, the elements of a gas reducer 20 (or substantial portions of the elements of a gas reducer 20) is located within the external profile of the R or inside lengthening the outer wall of the cylinder 2, which reduces the number of points of collision with the gas reduction gear 20, when the container 2 falls or when it wrong turn when in use. As a rule, elements, placed inside the profile R, are the elements that influence the ability to maintain pressure in the system, or to affect its integrity. Thus, the gas reducer 20 is more compact and more durable than traditional gas regulators. Additional ensure the strength characteristics of the gas reducer 20 are described later in more detail.

The drawings additionally shown that the gas reducer 20 also contains fence 62 housing and cap 64. It should be borne in mind that despite the fact that the fence 62 housing and cap 64 shown as two separate details, these two components can be in the form of a single unified items or in the form of many parts, which is within the scope of the present invention. Cap 64 in one of the forms made from zinc alloy with aluminum, replacing the traditional brass, and the protection of 62 housing in one of the forms is made of a copolymer of Acrylonitrile, butadiene and styrene with average impact properties. However, it should be borne in mind that can be used and other materials including brass, which are durable and can withstand shock loads, which is within the scope of the present invention.

Let us now turn to a consideration of the fence 62 housing shown in figure 2 and 5-8; you can see that the path of the fence 62 housing is configured indicators 30 and 40 pressure (pressure gauges) are buried in holes 65, behind ribs 66 and front profile fence 62. Moreover, indicators 30 and 40 pressure are located inside the outer diameter "D" cap 64, as this is best shown PA figure 5. Thus, indicators 30 and 40 pressure better protected from damage upon impact, regardless of whether they are a fence housing 62 on the housing 22 or not.

Cap 64 in one of the forms attached 22 bolts 68. Thereby gain more short constructive profile gas reducer 20. It should be borne in mind that the cap 64 can be attached to the chassis 22 using other types of fasteners, such as, for example, latching or thread. You can also see that the cap 64 is embossed with outer surface of 70 close to handle 50 adjust the pressure, having ribs 72 and cuts 74, similar to handle 50 pressure adjustment.

Let us now turn to the consideration of figure 4 and 9, which shows that handle 50 adjusting the pressure is attached to the housing 22 using the trimmer item 80 and spring 82 compression, which are located inside the hood 64. Energy absorber in the form of the elastic element 84 is located between the handle 50 adjusting the pressure and the body of 22, and more specifically, rests on the inner recess 86 handle 50 adjusting the pressure and the inner ledge 88 cap 64. It should be borne in mind that handle 50 regulation of pressure in this form is not attached to the elastic element 84. In one of the forms ring 89 slip is placed between the elastic element 84 and internal plot handle 50 adjust the pressure, which reduces friction between the handle 50 adjusting the pressure and the elastic element 84. Note that one can also use other tools to reduce friction, such as lubricants, which is within the scope of the present invention.

Elastic element 84 made of a material which can deform or shrink, and absorb energy when the handle 50 adjusting the pressure applied shock loads. For example, in one of the forms elastic element 84 is made of durable urethane; however, keep in mind that also can be used and other materials that can be compressed and/or deformed to absorb the energy of impact loads, which is within the scope of the present invention. Such an application of the shock load shown in figure 10, where the balloon 2 drops in the direction of the arrow, and handle 50 adjusting the pressure directly collides with the earth or with the environment. When this collision, which can occur under different angles and perspectives that differ from those shown on the figure 10, then shock loads are transferred from the handle 50 adjust the pressure to the elastic element 84, which deforms and, thus, absorbs most of the energy of such a collision. This allows you to create a more durable gas reducer 20.

Let us now turn to the consideration of 11-13, which shows another form of energy absorption for use with handle 50 adjust the pressure, which applied shock loads. This power absorbing device contains a group of elements 92, 94 and 96. Typically, items 92, 94 and 96 gradually deformed and slow the handle 50 adjusting the pressure under impact loads. In principle, the greater the distance traveled during a strike, the less the impact force. In accordance with the present invention, the distance traveled during a strike, is a distance that handle 50 deformed/ pinched when the shock. More specifically, item 92 of the first stage is a wall 93, which goes along the Central section of the internal handle 50 adjusting the pressure and the terminal segment of 95. Wall 93 has a specific thickness of a "t", as shown in fig.13, so that, under impact loads, tail section 95 in contact with the cap 84 and when the load reaches the specified limit, the wall 93 spreads and squeezed. Then the item 94 of the second stage, which contains many of the angular walls 97 located around the inner periphery handle 50 pressure adjustment. Under impact loads, after squeezing wall 93 item 92 of the first degree, as mentioned here above, the angle of the wall 97 then move closer to 84, with continuous movement of the handle 50 pressure adjustment. When the angular walls 97 mesh with cap 84, they gradually PA cap 84 so that handle 50 adjusting the pressure tends to deform outwards under the effect of wedging. This and deformation further reduce speed handles 50 adjusting the pressure under impact loads. Then acts item 96 of the third stage, containing many coming out of him pins 99. Under impact loads, after wedging angular walls 97 the cap 84, as mentioned here above, pins 99 mesh with cap 84 to further slow down the speed knob 50 pressure adjustment. After the input pins 99 engages with the cap 84, item 96 deformed and advanced slows handle 50 pressure adjustment. Thus, through this series of consecutive gearings elements 92, 94 and 96 cap 84, energy absorber encourages handle 50 adjusting the pressure squeezed inside and slide over the cap 84 under high shock loads. Such loads can be, for example, approximately 8,000-9,000 pounds of force. By the defined technical solutions, these can be absorbed handle 50 adjust the pressure, causing serious damage to a gas reducer 20, to allow for a more robust design. Furthermore, the reduced potential risk of damage to the cylinder 2 or gas supply system.

Despite the fact that a group of elements 92, 94 and 96 are shown as educated as a single whole with handle 50 adjust the pressure, it should be borne in mind that can be used separate elements, which is within the scope of the present invention. In addition, it should be borne in mind that the number and specific configuration items 92, 94 and 96 are just an example, and should not be construed as limiting the scope of patent claims of the present invention.

It should also be borne in mind that specific device absorption of energy, namely, the elastic element 84 and group items 92, 94 and 96, are just an example, and should not be construed as limiting the scope of patent claims of the present invention. Various devices absorption of energy may be used with a handle 50 adjust the pressure, which are located inside, as described here above with reference to the drawings, or outside, which is within the scope of the present invention. As such, specific devices energy absorption described here above with reference to the drawings, do not limit the scope of patent claims of the present invention.

How this is best shown in figure 2, 5 and 6 as cap 64 and handle 50 pressure adjustment contain different display to give users information about where and how to operate the various functions. For example, the cap 64 see the indication "LP" low pressure and arrow 100 close second indicator 40 gas pressure, to indicate that this indicator shows low pressure or the pressure of the gas escaping from the regulator. Similarly, see the indication "N.R." high pressure and arrow 102 nearby from the first indicator 30 gas pressure, to indicate that this indicator shows a high pressure or gas pressure inside the bottle of 2. On the handle 50 adjusting the pressure is given indication 104, which provides the information that the rotation of the handle 50 clockwise increases the pressure, and rotation of 50 counterclockwise decreases the pressure. It should be borne in mind that can be provided other types of display, including (but without limitation) using a LED to show dangerous levels of pressure, which is within the scope of the present invention.

On fig.15 and 16 shows the alternative types of gas reducers, designated positions 200 and 210. Gas reducer 200 fixed on the tank (not shown) with rear inlet (rear station inlet so, that the handle 50 adjusting the pressure is vertical and facing up. In this way, despite the fact that the indicators 202 and 204 of the gas pressure read in a horizontal or linear configuration, this should be interpreted and construed as "vertical configuration", in the sense in which this term is used in the description of the present invention. Alternatively, gas reducer 210 fixed on the tank (not shown) with rear inlet so, that the handle 50 adjusting the pressure is vertical and the faces down. Similarly, although indicators 202 and 204 of the gas pressure read in a horizontal or linear configuration, this should be interpreted and construed as "vertical configuration", in the sense in which this term is used in the description of the present invention. These and other installation configuration does not go beyond the present invention.

It should be borne in mind that the present invention is not limited option, described and shown on the drawings as an example. For example, the use of gas reducer in accordance with the present invention is not limited to applications for acetylene-oxygen cutting, and declared gas reducer can be used in other applications, which allow you to use the advantages of the disclosed here constructions.
