  • a Trinox gas is supplied to the head space of the container 2 via a Trinox channel 35 coupled to the channel 29 from a Trinox gas space 36 in order to adjust the filling height within the container 2 reach, in such a way that the level of contents within the container 2 corresponds to the lower edge of the gas pipe 15.
  • FIG. 11 shows a second alternative embodiment of the filling system according to the invention similar to the embodiment according to FIG. 10.
  • the essential difference from the embodiment according to FIG. 10 consists firstly in the fact that in the region of the second gas channel 21 of the gas valve body 17 no throttle is provided for reducing the gas flow through the hollow needle gas valve body 17 but the throttle is displaced to the outside, in the region the line 33, the third gas channel 34 with the other Gas space 26 connects. Furthermore, the line 33 between the third gas channel 34 and the other gas space 26 at least one branch point 38, by means of which the channel formed in the conduit 33 branches into two or more mutually parallel channels 39, 40, wherein all of these parallel channels 39, 40 open into the further gas space 26.
  • a control valve 32 a, 32 b is provided, by means of which the individual channels 39, 40 are each independently visible or closable to establish a connection between the third gas duct 34 and the other gas space 26 to be able to.
  • Throttles 41, 42 are provided in the mutually parallel channels 39, 40, by means of which the volume flow through the respective channels 39, 40 is limited.
  • the throttles 41, 42 of the channels 39, 40th are provided in each of these mutually parallel channels 39, 40, by means of which the volume flow through the respective channels 39, 40 is limited.
  • the throttle 39 has a smaller bore than the throttle 40, so that the throttle 39 allows a lower volume flow than the throttle 40 (each at a constant pressure within the other gas space 26).
  • the volume flow through the third gas channel 34 or the line 33 can be changed by selecting the opened channel 39 or 40, depending on the type of rinsing method. This is of considerable advantage in particular if both filling of the containers with vacuum support (for example glass bottles) or without
  • Vacuum support e.g., PET bottles
  • Vacuum support can be made, since depending on the prevailing in the container to be filled rinsing the volume flow into the other gas space 26 can be changed.

Abstract

L'invention concerne un système de remplissage de bouteilles ou de récipients similaires (2) avec un produit à conditionner liquide, comprenant : une cuve de produit à conditionner (1) dans laquelle sont formés, pendant le remplissage, un espace liquide inférieur (1.1) occupé par le produit à conditionner et un espace gazeux (1.2) situé au-dessus de celui-ci ; au moins un élément de remplissage (4), disposé en-dessous de la cuve de produit à conditionner (1), qui comprend un boîtier d'élément de remplissage (7) dans lequel est formé un conduit de liquide (8), relié à l'espace liquide (1.1), qui forme sur une face inférieure du boîtier d'élément de remplissage (7) située à l'opposé de la cuve de produit à conditionner (1) un orifice de distribution du produit à conditionner (10) ; une soupape à liquide (11), disposée dans le conduit de liquide (8), qui comprend un corps de soupape (12) qui est monté sur un poussoir (13) aligné avec un axe (FA) de l'élément de remplissage et qui peut se déplacer dans le sens axial pour ouvrir et fermer la soupape à liquide ainsi que pour délivrer de manière commandée le produit à conditionner dans le récipient (2) monté sur l'élément de remplissage (4) ; un premier conduit de gaz (14), formé dans le poussoir de soupape (13), qui débouche à une extrémité supérieure dans l'espace gazeux (1.2) de la cuve de produit à conditionner (1) et à l'extrémité inférieure dans un espace de tête du récipient (2) monté sur l'élément de remplissage (4) ; une première soupape de gaz (16), disposée dans le premier conduit de gaz (14), qui comprend un corps de soupape de gaz (17) qui peut se déplacer afin d'ouvrir et fermer la première soupape de gaz (16) ; et au moins un élément actionneur (18) qui coopère avec le corps (17) de la première soupape de gaz (16).
