Description

"Gate direction for spraying liquids"

The price increase relates to a device for spraying liquids using a suitably filled with liquid gas Pressurized gas container, which is releasably connected by means of a bridge to a container containing the spray material, including the Bridge is provided with two connecting pieces for the spray material and pressurized gas container, also an effective one based on the injector principle Aerosol can and a riser pipe protruding into the spray container at one end, the other end into the Area of the spray nozzle is sufficient.

such devices are known. In known embodiments, however, the manufacture of the nozzle and the stem pipe mouth relatively expensive. For this purpose, namely in the mouth of the plastic bridge penetrating compressed air channel, as well as in the mouth of the riser there are metallic, tubular, Inserts made by machining are firmly arranged.

_ 2 -

These inserts also have turned flanges which are attached at such a height that after the inserts have been placed in the channel mouths assigned to them, whereby the inserts must be installed one after the other, a positionally correct arrangement is guaranteed. Furthermore, in such embodiments When changing the spray material, the bridge is cleaned, in particular cleaning the relatively small nozzle bore and the riser mouth extremely time consuming Sst.

The task of the innovation is now based on the injector principle to create an effective device for spraying liquids that eliminates these deficiencies »

This object is essentially achieved in that the device a releasably connected nozzle with two in the correct position, that is, in their axial extensions approximately at right angles to one another extending, connected to the respective supply channels • ^ • assigned outlet openings for the compressed gas and the spray material is.

There is also an advantageous and inventive feature The above-described object is that the nozzle, which is preferably made of plastic, is secured by a screw, bayonet lock or the like is releasably connectable to the device.

As a result of these measures, the manufacturing and assembly costs for the object are considerably lower than with known ones • Embodiments. Furthermore, when changing the spray material even the very cheap nozzle can be replaced so that the time-consuming cleaning of the nozzle is no longer necessary.
