DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an outflow nozzle comprising a support with an outflow element pivotally arranged therein. The outflow element has a spherical end confined so that it rotates inside a cavity of the support.
BACKGROUND OF THE INVENTION
Such an outflow nozzle is generally known in the prior art. In this case the outflow element at the inflow end comprises a spherical part which can be accommodated in a corresponding cavity of the support. Such outflow nozzles have many applications, such as in ventilation systems for cars and aircraft, but are also used in baths and the like. Fitting the outflow element in a hinged manner ensures that the emerging flow, such as air, is directed as desired on, for example, the user. If directing at more than one place, for example for more than one user, or at several places is desired by a user, it is known in the prior art to produce multiple outflow nozzles comprising a number of adjacent outflow nozzles of the type described above.
However, such an embodiment has a number of disadvantages. On account of the considerable space taken up by the hinged fitting, there is a considerable distance between the different outflow nozzles, and in the region between said outflow nozzles no flow can be produced. For certain applications it is necessary to release the emerging medium in a relatively thin jet, in order to maximize the effect experienced. With the use of different adjacent outflow nozzles a very complex control is necessary for this. Besides, there is the disadvantage that the outflow apertures of the outflow elements, which are generally round, are difficult to grip and to position, in particular in situations in which they are smooth, as in the case of use under water.
SUMMARY OF THE INVENTION
The object of the present invention is to avoid these disadvantages. This object is achieved in a device of the type described above in that the outflow element comprises at least two adjacent outflow pipes, while each outflow pipe is provided with a spherical part, and the spherical parts of the outflow pipes together essentially form the spherical end.
The invention is based on the idea of dividing the outflow element into a number of outflow pipes. In this case the inflow end of the outflow pipes is always in the form of a spherical part, and all spherical parts of the adjacent outflow pipes together form the spherical end, as known in the prior art.
The movement of the outflow pipes according to the invention relative to each other in a first embodiment of the invention is carried out in such a way that they can only slide along each other. In other words, only positioning of the outflow pipes differently from each other about a line of rotation of the spherical end of the spherical element is possible.
According to a further advantageous embodiment, not only is rotation of the outflow pipes relative to each other possible, but displacement is also possible. For this, it is necessary for at least one boundary face of adjacent spherical parts to be curved and positioned with the top of the curve near the center of rotation for moving them towards or away from each other. With this embodiment not only does sliding along each other take place, but a combined rotating, tilting and sliding movement can also be achieved. Such an embodiment is a particular advantage if three outflow pipes are present, the outflow pipe lying in the center being provided with flat boundary faces, and the outflow pipes adjacent to it being provided with the above-described curved boundary faces.
With the device according to the invention it is possible in an aesthetically simple way to make the outflow end of the outflow pipes essentially rectangular. It has been found that, in particular in circumstances in which gripping these pipes is difficult, making them rectangular provides an improved grip compared with the usual round embodiment.
Although it is possible with the outflow nozzle described above to meter a fluid, it is also possible to convey two or more flui
