Additionally, these return springs are often difficult to install
The cost of the dispensing system is thus increased, which is a disadvantage especially in the case of disposable domestic tap systems

Embodiment Construction
[0045]A device 1 ( FIG. 1 ) for dosing liquid B (eg beer) from a container 2 comprises an outflow channel 3 to be connected to the container 2 and capable of being closed off by a liquid valve 4 . The outflow channel 3 has an outlet portion 5 which is connected by means of a ball joint 6 to a horizontal portion 7 which in turn is clamped within the widening of the pipe elbow 8 . This pipe elbow 8 forms part of a button 9 which snaps onto a segmented cylindrical air valve 10 which in turn forms part of a blow-out means 36 which will be discussed in more detail below.
[0046] The vertical part of the pipe elbow 8 herein extends into the inner casing 11 of the gas valve 10 , and the liquid valve 4 is also installed inside the inner casing 11 of the gas valve 10 . The liquid valve 4 is also in the form of a segmented cylinder and has a T-shaped channel 12, one leg of which extends axially through the narrow part of the valve 4 and the other leg extends transversely through the wi...

The invention relates to a method for dosed dispensing of a liquid from a container that is connected to an outflow channel that may be closed off by a liquid valve, comprising opening the liquid valve, dispensing a dose of the liquid from the container through the outflow channel and closing the liquid valve, and blowing empty the outflow channel after closing of the liquid valve. During dispensing of the liquid a pressure in the container may be higher than atmospheric pressure and the liquid valve may be biased to its closed position by this higher than atmospheric pressure in the container. The invention further relates to a device for dosed dispensing of a liquid from a container, comprising an outflow channel that can be connected to the container and that can be closed off by a liquid valve, and means for blowing empty the outflow channel when the liquid valve is closed. These blowing empty means can be adapted to connect the outflow channel with a source of gas under higher than atmospheric pressure when the liquid valve is closed.
Description
technical field [0001] The invention relates to a method of dispensing a dose of liquid from a container connected to an outflow channel which can be closed by means of a liquid valve, the method comprising: opening the liquid valve, dispensing a quantity of liquid from the container through the flow channel and closing liquid valve. This method is generally known and is applied, for example, when drawing beer from a container. Background technique [0002] The known method has several disadvantages. [0003] The outflow channel, for example, will usually have a bend or bend, and after closing of the liquid valve, a small amount of liquid will usually remain in those parts of the outflow channel that extend substantially horizontally. This liquid will then drip out of the outflow channel later, which can contaminate the vicinity of the container. This is particularly inconvenient in the case of so-called domestic tap systems, in which the container stands on a kitchen wor...
