ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a single-chamber filling system.
2. Background Information
The prior art discloses filling systems of this type in a wide variety of realizations.
OBJECT OF THE INVENTION
The object of the present invention is to describe a filling system that makes it possible, utilizing a simplified design and construction, to adjust a filling height by means of Trinox in a particularly reliable manner.
SUMMARY OF THE INVENTION
The present invention teaches that this object can be accomplished by means of a single-chamber filling system for filling bottles or similar containers with a liquid product, characterized by a Trinox duct that holds a gas, preferably an inert gas, at a second gas pressure which is greater than the first gas pressure, whereby the Trinox duct can be placed in communication via the control valve and a first gas pathway with the interior of the container that is fastened to the filling element, and whereby the pressurization gas valve can be realized in the form of a pressurization or tension gas and Trinox valve such that its valve body can open automatically when the gas pressure in the gas duct exceeds a specified pressure threshold which is higher than the first gas pressure but lower than the second gas pressure.
In the present invention, the pressurization gas valve or its valve body can simultaneously form the Trinox valve. The resulting configuration is simplified and particularly reliable.
In a preferred embodiment of the invention, in the first gas pathway, by means of which the interior of the container is pressurized with the Trinox pressure after the end of the filling and after the closing of the filling or fluid valve, to adjust the filling height and to push back excess product through the return gas tube into the fluid space or bowl, an element that reduces the gas flow, for example in the form of a throttle or nozzle, can be provided. As a result, in connection with the special realization of the pressurization gas valve, the Trinox pressure in the filled container (bottle) is largely independent of fluctuations of the gas pressure in the Trinox duct.
In other words and in accordance with at least one possible embodiment of the present invention, a first gas pathway can be used to pressurize the interior with Trinox pressure after the end of the filling and closing of the fluid valve. A nozzle, throttle or restrictor can be positioned in this first gas pathway to reduce the gas flow.
Refinements of the present invention are disclosed in the features and subclaims.
The above discussed embodiments of the present invention will be described further hereinbelow with reference to the accompanying figures. When the word “invention” is used in this specification, the word “invention” includes “inventions”, that is, the plural of “invention”. By stating “invention”, the Applicants do not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicants hereby assert that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
