The shank 9 has an internal screw thread for fastening by screwing together with other connectors to the collector of the distributor, in turn, is connected to the supply device of the latter. The head 8 is designed for going down in the seat 6 of the container 1.

The cylinder 1 and the connector 2 are connected by a bayonet connection. To provide a bayonet connection, which is shown in detail in Fig. 2 and 3, the head 8 of the connector 2 includes an annular group of protrusions 10 and, accordingly, the seat 6 of the container 1 has a ring group relief portions 11, each connected with a corresponding protrusion 10 of the connector 2. In particular, each of the ridges 10 of the connector 2 provides a surface for contact with a corresponding relief part 11 of the container 1, while the mentioned account is the X-axis of the connector 2, the second part 13, is inclined relative to said plane, and a third portion 14, which is attached to form recesses; on the other hand, each embossed portion 11 seats 6 of the container 1 provides a shaped piece of gear 15, which is intended for insertion into a deep part 14.

As shown in Fig. 5, the valve 7 of the container 1 contains a Cup-shaped housing 16, a bottom part which has an opening 17, which provides the message to the internal part of the cylinder with the interior of the housing; the housing 16 is closed on top by means of a spacer 18 having a Central hole 19, which provides access of the corresponding element to the inner side of the housing, as will be shown next. In case 16 enters the hollow locking means 20, held pressured on the gasket 18 spiral spring 21, a portion of which partially screw around locking means. The spring 21 has a constriction 23, in which is held the ball 24.

The body 16 of the valve 7 comes into a hollow cylindrical part 25 of the dome 5, which is essentially a type of outer casing of the valve. Part 25 on the outer side surface has a screw thread 26, and has an upper part that locks the gasket 18 in the valve housing to anaru 3 by double folding.

As shown in Fig. 4, the bottom portion 28 of the container 3 has a bulge toward the inside of the container. In addition, the lower edge 29 of the base 4 of the container 3 is formed in the shape of the curb by an appropriate bending back the connecting part between the base 4 and a bottom part 28.

As shown in Fig. 10, the connector 2 includes within its hollow head 8, the finger 30 is made integral with the head. The finger 30 is made of the axial channel 31, which on the one hand communicates with the transverse hole 32 made from one end of the finger and leading into the cavity of the head 8; on the other side of the channel 31 communicates with the conical mounting seat 34, also made in the finger and extending into the cavity of the shank 9. In seat 34 enters ball locking means 35. In the cavity of the head 8 at the level of the finger 30 is enclosed sealing ring 36. The shank 9 is provided with a diaphragm locking means 37, elastically held the seat 38 by a coil spring 39 attached to the inner wall of the shank. In addition, the shank 9 at the level of the seat 38 in the opposite position relative to the housing 34 of the finger 30 is provided additional konice the same.

The following describes the operation disclosed above system connecting the tank.

First of all, as shown in Fig. 6 and 7, make the filling tank with fuel gas through the respective device of a known type, in General, not represented, which contains the charging nozzle And inside the axial channel To deliver the message to the end of the nozzle with a cross hole going out. Charging (Fig.6) the nozzle And insert centered in the holes 27 and 19 of the valve 7 of the container (shown in Fig.5), the above-mentioned nozzle is partially injected into the hollow locking means 20 of the valve 7 and move it away from the position closing the valve 7 against the action of spring 21. At this point, is provided for combustible gas from the charger into the cylinder through the channel and the hole of the nozzle And the inner part of the housing 16 of the valve 7 and the opening 17 of the housing. As soon as the tank is charged by the fuel gas, the nozzle And then injected into the valve 7, while the locking means 20, push the nozzle down, do not disconnect the ball 21 from the constriction 23 of the spring 21 (Fig.7). Once the coupling ball 24 is moved into the opening 17 and at this point the nozzle And ejected out of the holes 19 and 27 of the valve 7, and the spring 21 returns superuse what obedinitel 2 cylinder fitted on the connecting means so what depth seat 6 cylinder will be located on the head 8 of the connecting means with the tabs 10 of the head, placed on the bottom part of the seats 6 of the container between a raised parts 11 mentioned seats. At this point, the cylinder 1 rotates in the clockwise direction around the X-axis relative to the connector 2, so that the protrusions 10 zakladivaetsa between the raised parts 11 and the bottom part of the seats 6 cylinder, each embossed portion 11 is engaged with the corresponding projection 10 with the introduction of the relief part of the gearing 15 relief portion 11 against the recessed portion 14 of the projection 10 (Fig.3). Parts 12 and 13 of the projections 10 formed of the setting areas to perform the engagement. As shown in Fig. 11, when the head 8 of the connector 2 is in seat 6 of the container 1, the inner finger 30 of the connector comes into the holes 19 and 27 of the valve 7 (shown in Fig.5) and moves the locking means 20 to the side of the hole opposite to the action of the spring 21, the finger 30 acts like a nozzle And on the phase of charging. The strength of the elasticity with which the spring 21 has an impact on the locking element 20, is transmitted through the finger 30 to the connector 2 and streetscrack.com the elastic force, which keeps them in the engaged position. The sizes and arrangement of the projections 10 and the relief portions 11 such that the angle of rotation required for connection of the container 1 with the connecting means 2, is approximately 60.

As shown in Fig. 8 and 11, as soon as the container 1 is connected to the connector 2, the fuel gas flows from the cylinder to the connecting means through the internal bore 17 of the valve 7, through the interior of the valve, and then through the hole 32 and channel 31 (both shown in Fig.10) of the finger 30 of the connecting means; a ball 24 is pushed by the gas pressure to the constriction 23 of the spring 21. From connector 2 fuel gas flows to the dispenser by lifting the ball valve 35 from the saddle 34 and lifting the diaphragm valve 37 from its seat 38 is opposite to the action of the spring 39.

During normal flow of combustible gas from the cylinder 1 to the connector 2 ball 35 remains suspended in an intermediate position between the mounting seat 34 and opposite the landing place of the connector 40 and functions as a flow limiter.

In that case, when the pressure of fuel gas escaping from the cylinder 1, is exceeded, as shown in Fig. 12, the ball 35 is pushed by the actual pressure of the gas to the housing case, when the container 1 and the connector 2 is inadvertently turned upside down, as shown in figure 13, the ball valve 35 sits on the seat 40 by preventing the combustible gas and, in particular, its liquid phase was reached distributor.

As shown in Fig. 11, 12 and 13, in addition to the gasket 18 between the outer casing of the valve 7 of the container 1, that is, the cylindrical portion 25 (shown in Fig.5) dome 5 and the inner wall of the head 8 of the connector 2 is installed, the gasket 36 to prevent gas leaks out when the container is connected to the connector.

When the container 1 expended, to replace it, disconnect from the connector 2 by means of rotation of the cylinder in a counterclockwise direction relative to the connector and subsequent discharge from the connector. The angle of rotation in the counterclockwise direction is about 60or equal to, and opposite in direction to the rotation angle required for connection of the container 1 to the connector 2. During disconnection of the container from the connector finger 30 of the connector is released from the valve 7, and a hollow locking element 20 is returned to the closed position of the valve (Fig.5).

It is evident from Fig.10 it is obvious that as soon as the container is disconnected from the connector 2, the Engl is medinites thanks diaphragm locking means 37, held by the spring 39 in the locking position of the channel for the gas inside the shank 9 of the connector. If for some reason the diaphragm locking means 37 does not provide a seal, the gas will be stopped by the ball 35, which will save the actual gas pressure at the seat 30 of the connector, preventing communication between the interior of the shank 9 and the inner part of the head 8 and, therefore, leakage of gas from the connector.

When the container 1 is consumed, it cannot be reused and should be disposed of. As shown in Fig.9, if an attempt is made to re-fill the tank by introducing the indicated position And the nozzle charger, gas pressure, which flows into the valve 7, provides forcing the ball 24 into the hole 17, thus there is a blockage of the holes and the gas will not be able to flow inside the cylinder.

The system described above the connection of the cylinders has a number of advantages.

First of all confirmed that the connection shown between the cylinder 1 and the connector 2 is very simple, fast and effective due to the fact that the connection requires a minimum rotational action and, in addition, the Zats what I, therefore, a reliable seal. Preferably, the angle of rotation for connecting the container to the connector amounted to no more than 60.

As you can see, ball locking means 35 and diaphragm locking means 37 of the connector 2 to guarantee maximum safety in case of detached cylinder, preventing the leakage of fuel gas from the connecting means; in addition, ball locking means 35 provides additional security by preventing the flow distributor of gas under pressure or liquid phase; finally, ball locking means 35 mainly acts as a flow limiter.

As shown, the ball 24 of the valve 7 of the container 1 prevents fraudulent re-filling of the container disposable.

It should be added that as the cylinder device 1 and the device connector 2 is simple and therefore economical from the constructive point of view. In fact, the body of the container 1 is formed of only two parts, that is, from the cylindrical container 3 and the dome 5; the valve 7 of the container and the connector is also formed from a small number of parts. As you can see, part of the dome 5, that is, the hollow cylinder is Lena in the above-mentioned cylindrical part 25.

The fact that the container 1 consists of only two parts connected with each other by double folding, can be very resistant to stresses caused by the pressure of the combustible gas is loaded into the container. Concentric circular ribs 22 of the dome 5 increase the strength of the dome at the level of the connection zone, where the voltage is particularly high. Curb edge 29 of the base 4 of the container increases the strength of the base.

Having a smaller base 4 provides the ability to capture a cylinder and its easy connection to the connector without interference from other adjacent cylinders attached to the distributor.

The screw thread 26 of outer casing 25 of the valve 7 of the container 1 allows you to connect the cylinder to the usual screw connectors.

Obviously, what can be done, options and/or additions to what is described and shown above.

The overall configuration of the container and the connector can be changed.

You can create a bayonet connection elements connecting the cylinders, functions equivalent to the functions of the elements described and shown above, although the last confirmed that they are particularly simple and reliable.

Hollow saperaud what goracymi, performs the same function.

The locking balls 24 and 35 can also be replaced with locking elements that perform the same function, such as the pistons are guided in the respective saddles.

Of course, the above system connecting the cylinders can also be applied to the dispenser, with one connector and is therefore intended for use with one tank. However, it was found that the system is particularly suitable for managers with a large number of cylinders, providing quick installation of cylinders on the connectors of the distributor.
