comportant une cuve collectrice pour le liquide à soutirer, de prévoir une soupape pour exercer une certaine pression dans la cuve collectrice en partant d'une conduite à air comprimé, lorsque&#65533; à cause de fuites en un endroit quelconque, il se produit une perte de pression et que la cuve collectrice menace de se remplir de liquide. Il est également déjà connu de disposer dans le même but au-dessus de la cuve une soupape présentant la  forme d'une soupape à membrane.

  
L'invention a en vue un problème un peu différent. Ainsi,

  
il a .été reconnu comme nécessaire dans les soutireuses pour assurer une bonne conservation de la bière en bouteille d'abandonner les récipients collecteurs utilisés jusqu'ici, lesquels sont remplis de bière et d'air comprimé et dans lesquels a lieu le déplacement de l'air comprimé vers

  
 <EMI ID=3.1> 

  
A sa place, on utilise une tuyauterie remplie de bière, de laquelle la bière est dirigée directement vers les bouteilles. Dans les soutireuses de ce genre, qui travaillent avec écoulement direct du liquide de remplissage hors d'une tuyauterie complètement remplie, il est nécessaire de faire dépendre la pression de l'air d'échappement de la pression du liquide à soutirer, au moyen d'une soupape connue en soi et de faire en sorte au moyen d'un dispositif spécial que cette pression soit toujours maintenue même en cas de fuites.

  
La présente invention est destinée à résoudre ce problème. L'invention consiste en une combinaison de la soupape d'air d'échappement avec une soupape spéciale, qui provoque une pression au sortir d'une tuyauterie à air comprimé de pression quelconque lorsque la pression d'air

comprising a collecting tank for the liquid to be withdrawn, to provide a valve to exert a certain pressure in the collecting tank starting from a compressed air line, when &#65533; due to leaks anywhere, a loss of pressure occurs and the collecting vessel threatens to fill with liquid. It is also already known to arrange for the same purpose above the tank a valve having the shape of a membrane valve.

  
The invention has in view a somewhat different problem. So,

  
it was recognized as necessary in the filling machines to ensure a good conservation of the bottled beer to abandon the collecting vessels used until now, which are filled with beer and compressed air and in which the displacement of the lager takes place. 'compressed air to

  
 <EMI ID = 3.1>

  
Instead, a piping filled with beer is used, from which the beer is directed directly to the bottles. In fillers of this kind, which work with direct flow of the filling liquid out of a completely filled pipe, it is necessary to make the pressure of the exhaust air depend on the pressure of the liquid to be withdrawn, by means of 'a valve known per se and to ensure by means of a special device that this pressure is always maintained even in the event of leaks.

  
The present invention is intended to solve this problem. The invention consists of a combination of the exhaust air valve with a special valve, which causes pressure to come out of a compressed air piping of any pressure when the air pressure

The adjustment is thus effected by the pressure of the liquid to be withdrawn in combination with a spring whose tension is adjusted according to the pressure of the exhaust air.

The invention is shown in the accompanying drawing by way of example and schematically.

The pressure of the exhaust air is regulated by increasing or

The bottle is vented into the atmosphere as soon as its pressure increases to such an extent that it exceeds the liquid pressure and the spring pressure.

In addition, according to the invention is provided a second membrane valve B. The face 5 of its membrane is in connection with a compressed air pipe 6 of any pressure, and further with the upper part of the membrane valve. 4 by piping 7.

If, as a result of some accident (broken cylinder or the like), the exhaust air pressure drops, then the liquid pressure
