ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to an apparatus for the ejection of liquid.
With such apparatuses articles and surfaces can be cleaned or processed.
BRIEF SUMMARY OF THE INVENTION
It is an object of the invention to provide an apparatus of the initially named kind which permits a most effective cleaning or treatment.
This object is satisfied in that a plurality of rotor nozzles are provided which are combined into a unit, with each rotor nozzle having a rotor space formed in a nozzle housing and having an inlet opening in the region of its one axial end and an outlet opening for the liquid at the other end, as well as a rotationally driven rotor arranged inclined in the rotor space relative to its longitudinal axis and supported at the inner wall of the rotor space, the rotor having, at its end pointing towards the outlet opening, a nozzle region supported in a cup bearing and an inflow opening at the opposite end.
With the rotor nozzles provided in accordance with the invention, which can also be termed rotary nozzles, the liquid, in particular water, can be ejected in the form of a conical liquid jet. The combination of a plurality of rotor nozzles into a unit thus also permits an effective and time-saving cleaning or treatment of larger surfaces and articles. Moreover, through the combination of a plurality of rotor nozzles a compact and thus space-saving ejection or expulsion apparatus is provided.
Rotor nozzles can be used over a wide range of liquid pressures and indeed already from a normal mains water pressure of about 3 bar up to pressures of several hundred bar, such as are for example customary in high-pressure cleaning apparatuses. The invention consequently opens up a large variety of possibilities of use both in private houses and in the garden area (for example as a garden shower with a vertically extending nozzle housing) and also in the professional and commercial environment and indeed for example for cleaning, surface treatment, sprinkling and/or watering purposes. Speeds of rotation of the rotor of approximately 300 revolutions per minute are already achieved in the low pressure region. The expulsion apparatus of the invention can be made mobile or stationary, for example arranged on a conveying means for materials or articles to be cleaned or processed.
In accordance with a preferred embodiment of the invention, the nozzle housing is of plastic and is preferably manufactured using an injection molding process.
This makes it possible to manufacture an ejection apparatus with low weight simply, quickly and at favorable cost.
In accordance with a further preferred embodiment of the invention, the outlet opening and/or the cup bearing of each rotor nozzle are formed on a separate plug, which is inserted into the rotor space and sealingly connected to the nozzle housing, preferably fused thereto.
The assembly of the expulsion apparatus is simplified in this way, since after the manufacture of the nozzle housing, in which the individual rotor spaces are already formed, only one rotor has to be inserted into each rotor space and then the rotor space closed by means of the plug.
