be carried out so that foaming is avoided, that a lowering of the liquid level in the bottle "a loss of diluted syrup and a decrease of the carbonic acid displacement of the liquid in the Bring a bottle »

The groaning occurs as a result of various factors, however, two of these factors that cause the major problems are the wet pre-gassing and the Speed of venting · Hate pre-gassing is on due to the rapid discharge of residual liquid that was in the gas tube as a result of the upward flow of the Liquid is contained in it during the previous filling process. An over-rapid venting is carried out one blow for. the contents of a bottle and it's up demonstrated that this also happens when the gas passes through an opening of the smallest possible dimensions is given will.

A purpose of the invention is to provide a filling valve arrangement which avoids soaking due to excessive venting and wet pre-gassing and, in general, to provide a valve which permits high filling speeds and which has structurally advantageous properties.

that he slowly touches the inside walls of the bottle flows downwards and so no when it comes into contact with the syrup The syrup is swirled up, which could cause foaming if the pressure in the bottle occurs is then dismantled *

This flow of liquid displaces the gas and air in the bottle so that it goes up through the openings 48 and 49 in the stopper 44 and the holes 50 in the nozzle 45 flow and through the gas pipe back into the container, which contains the majority of carbonated water.

This continues until the liquid level reaches the plug 44 and flows upwards through the nozzle 45. The holes 45 »openings 49 are to have too small a, considerable liquid flow hindurchtireten through them _r, so that the liquid flows as a jet through the nozzle 45 and closed at the top bushing 46 rises, so that the valve 47 calibrated to the valve seat 43 sets «Since no further displacement of the gas can take place _f the flow of liquid through the valve ceases.

With further movement of the valve arrangement, the upper arm of the hook 34 comes to a second fixed stop to the plant that a lowering of the valve rod 26

Those in the channels 11, 12 and the annular space 10 the liquid is under pressure and is discharged through the vent valve together with the excess, that above the liquid level in the flasohe submitted. The liquid supply valve closes due to the relatively higher pressure on its Inlet side.

The pedestal is then lowered so that the valve assembly returns to the position shown in Fig. 1, whereupon the cycle begins all over again «

During the venting process, due to the fact that liquid together with the gas. is discharged, regulated Gasabgabegesohwindigkeit by the simultaneous flow of liquid so that no foam formation may take place · In the same manner 'j occurs due to the V _e ntils 9 no liquid in the gas pipe θ a, so that during the Vorbegasens no Into flinging The liquid in the bottle

The cam stop is arranged in such a position that it only rests against the crouch when the bell-shaped filling tube and accordingly the crouch are raised into the position shown in FIG. So is the squatting in rest position when no bottle in the corresponding U _n is tersatz present. If a bottle breaks during the filling process a, the ropes immediately return to the position shown in Fig. 1 and thus shut off the gas and liquid supply.

As a result of the fact that the action of the liquid ~ supply valve 13 depending on the gas pressure in the bottle no timer mechanism is required. Be is no unnecessary delay of filling necessary after the pre-gas pressure has been reached «

The valve 23 creates a fully effective seal, while it works very simply, especially when it is wet, which contributes to the wear and tear of the reduce the entire valve group ..,
