DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a manually operable discharging apparatus for media.
Numerous discharging apparatuses are known, in which in addition to a media pump, a further pump is e.g. provided for carrying out the pumping work when the discharging apparatus is in the overhead position or for pumping a second medium out of a separate vessel.


SUMMARY OF THE INVENTION

An object of the present invention is to provide a manually operable discharging apparatus which, in addition to the pressure source for conveying the media, has a pressure source for making available a pressurized gas flow in such a way that as a result in simple manner the discharging behavior in the vicinity of the discharge nozzle can be influenced.
According to the invention, this object is acheived in that a discharging apparatus of the aforementioned type is characterized by a manually pressure source, such as a compressed air pump, with which is associated a compressed air chamber, which is connected by means of a compressed air duct to the discharge nozzle.
The compressed air pump can be connected directly via a line or pipe connection to the discharge nozzle or e.g. to a pressure tank formed by the reception vessel for the medium or a separate pressure tank, which supplies the discharge nozzle, the pressure in the pressure tank simultaneously being usable for conveying the medium from the vessel towards the discharge nozzle.
It is particularly advantageous if the pressurized gas source is used for ultra-fine atomization, for cleaning connecting lines for the medium, for valve control and/or for similar purposes, so that even in the case of manually operable discharging apparatuses of a size which can essentially fit into a closed hand, or which can be readily held and operated with one hand, same can be produced with numerous functions, which are otherwise only possible in the case of discharging apparatuses connected by means of pipes to pressure sources or pumps. Thus, the discharging apparatus can be completely closed, autarchic apparatus, or which is independent from external pressure sources and which in overhung manner only has one storage vessel for the medium, a cap or the like closing the same and carrying the pressure sources, as well as an operating unit e.g. in the form of a single operating head, which leads to extremely handy dimensions and a simple construction with high operating reliability.
