Definitions
- the invention relates to a double jacketed gas cylinder, which, using a conventional gas cylinder inside, manages to increase surface contact with the column bushing and consequently the final stroke of the unit.
- Double-jacketed cylinders that achieve the objectives mentioned in the preceding paragraph are already known in the market, the purpose of the present invention being the contribution of certain novel aspects in some of the components of the set, which with their contribution improve in practice the behavior and performance of a gas cylinder of these basic characteristics.
- valve plug has only two components duly mechanically assembled together, one of which, the innermost one, allows the passage of inter-chamber gas to an inner cavity that surrounds the valve shaft and facilitates said pass through it when the valve shaft is operated from the outside.
- the other component of the valve plug that is placed on the previous one and helps with the interior in the conformation of the gas passage cavity, is usually normally topped on the outside by an annular gasket, which in turn It is pressed by an outer washer.
- the free ends of the straight cylindrical body of the inner gas cylinder are folded directly on the two valve and shaft plugs, so that they perfectly control the mounting and the subsequent stability of the different components.
- the outer washer of the valve plug is controlled in its assembly by an annular shoulder made in a projection of the outermost body of the plug, so that its immobility is substantially improved.
- the inner component of the valve plug which, like the outer one, is made of injected plastic and as a direct result of the injection, the annular seat is constituted for the arrangement of the corresponding sealing gasket with respect to the inner tube.
- the gas cylinder thus constituted is housed inside another tubular element, which shows an end portion of a frustoconical shape, which ends its general cylindrical component of straight generatrix.
- the straight area of this tube is longer than that of the gas cylinder, and the latter is received within this portion until a physical stop is made at the beginning of the conical trunk end.
- the gas cylinder is received inside, with the output of the valve plug shaft towards said truncated conical end.
- a corresponding outer stop tube is previously accommodated thereto, which internally incorporates a pusher in which the end of the valve plug shaft sits.
- the tube-stop is of reduced thickness and is grooved externally by a series of longitudinal ribs that maintain the resistance of the piece with a substantially lower weight, while acting as a stop for the penetration of the inner gas cylinder.
- notches are made in the latter, which protruding inwards, they keep said cylinder effectively secured.
- the notches are made in a number of three, regularly distributed with a separation of 120 degrees between each two.
- the space between the section in which the notches are practiced and the free end of this outer tube is the one that increases the length of the cylinder in practice.
- This outer tube is fixed at one of its ends to the projection of the axis of the gas cylinder so that in the most extended position of this axis the bushing has a greater bearing surface in the tube and consequently with a greater positional stability.
- FIG. 1 is a longitudinal sectional view of a gas cylinder, according to the invention.
- Fig. 1A is a view of the valve plug of fig. one.
- Fig. IB is an exploded view of the valve plug of figs. 1 and 1A.
- FIG. 2 is an enlarged detail of the arrangement of the closing washer of the valve plug.
- Figs. 3 and 4 are two views of the inner body of the valve plug.
- - Fig. 5 shows the tube that hugs the gas cylinder.
- - Fig. 6 represents the tube with the gas cylinder housed inside, with the cylinder axis inserted.
- - Fig. 7 is the result of the I-I view of fig. 6.
- Fig. 8 shows the tube and cylinder mounted, with the cylinder axis in the extended position.
- Fig. 9 shows two views of tube-stop.
- - Fig. 10 represents the final assembly of the bushing and the outer tube in the position in which the axis of the cylinder is housed in said cylinder.
- fig. 10 a represents the same set as fig. 10 a , with the cylinder axis in its most extended position.
- the exterior is straight cylindrical cylindrical, and the interior space is traveled by the piston (27) associated with the axis (6) of the cylinder, constituting two chambers (4, 5) connected to each other by the space (3) inter-chambers.
- the gas passes from one chamber to another through said space through the communication steps established in the two caps, of the shaft (7) and of the valve (8, 9), all this when the protruding valve shaft (12) is operated outward.
- the tube (14) of fig. 5 presents a cylindrical shape of a straight generatrix in almost its entire length up to one end except for a left end (15) in a truncated conical shape.
- the gas cylinder (1) is housed and previously, the stop tube (19) is received, which includes the pusher (18) inside.
- the cylinder is housed by its outlet end of the valve shaft (12) towards the stop tube (19), on which it rests, all of which remains in the straight cylindrical zone.
- the cylinder (1) is controlled inside the tube (1) by means of the realization of the three notches (17) that determine internal projections, as shown in fig. 7.
- valve shaft (12) can be actuated from the outside through the pusher (18), and the shaft (6) of the cylinder is capable of projecting to a greater or lesser extent, as expressed in fig. 8.
- the free end of the shaft (6) receives the final connection elements.
- the final assembly includes the contribution of the bushing (25) and the outer tube (26) that hugs it.
- the bushing (25) runs along the outside of the tube (14) and at its end (28) receives the connection with the cylinder shaft (6).
