DETAILED DESCRIPTION OF THE INVENTION

(8) FIG. 1 is a view of two nozzle devices 1 according to the invention which are inserted into one another. These two illustrated nozzle devices 1 have in each case a support 2 and also a nozzle element 4 which is received in this support. In this case, it can be seen that this nozzle element 4 is surrounded completely by a receiving projection 24 of the support 2. The nozzle element 4 in turn is formed in two parts and has an outlet 42. Reference sign 46 identifies a basic member of the nozzle element 4.

(9) Reference sign 44 identifies a recess, in particular an encircling recess, which in an inserted state surrounds the nozzle element. Reference sign A identifies a distance by which the nozzle element 4 is set back with respect to the support 2 or relative to the receiving recess or the receiving projection 24.

(10) Reference sign 12 identifies a sealing element which in the use state can be pressed against a line which discharges the flowable medium, in order thus to achieve a sealing effect. Reference sign 14 identifies an annular seat or an annular contact surface against which the sealing element 12 can be placed. In the installed position, the sealing element 12 can be clamped between this seat 14 and for example a mouth edge of a line.

(11) In the assembled state shown in FIG. 1, this sealing element is in turn clamped by an edge of the receiving recess 24 of the second nozzle device 1 (here the nozzle device 1 on the left-hand side), and can thus not get lost. Owing to the fact that the nozzle element itself is set back relative to the receiving recess 24 and in the region, the nozzle element or the end thereof (or the outlet 42) will not contact the further element, i.e. the basic member 46, and/or a region of the second nozzle device 1.

(12) Reference sign 26 identifies a recess which is a constituent of the first coupling means of the nozzle device 1. This recess has a straight-running edge portion 26a and an obliquely-running edge portion 26b. In this context, the terms straight and oblique are in each case defined relative to a circular line which serves perpendicular to the longitudinal direction of the nozzle device 1. The obliquely-running portion 26b, upon relative rotation of two nozzle devices 1 with respect to each other, serves to urge the two nozzle devices onto each other and thus to fasten them to each other.

(13) Reference sign S identifies a distance which indicates the extent to which the sealing element is squeezed or clamped when assembling two nozzle devices. Reference sign 48 identifies a piston element or a nozzle mouthpiece which is arranged in the nozzle element. In this case, preferably this piston element 48 is movable in the longitudinal direction L relative to the basic member 46 of the nozzle element. In addition, the basic member 46 forms a recess, in particular a cylindrical recess, which is suitable and intended for receiving a portion of this piston element 48.

(14) FIG. 2 is an external view of two nozzle devices 1 inserted into one another. It can be seen that the second coupling means is provided on the receiving recess 24 (more precisely, on the outer periphery thereof or the wall of the receiving recess), said means being formed here too by two projections 82 which extend in a radial direction or in a direction perpendicular to the longitudinal direction L.

(15) Reference sign 22 identifies a wing or a projection which makes possible manual turning of a nozzle device with respect to the longitudinal direction L. Furthermore, here too a further projection 82 which is a constituent of the second coupling means 8 can be seen, this projection 82 engaging in a recess 26 in the nozzle device illustrated on the right.

(16) It can be seen, however, that a clearance or a gap extending in the longitudinal direction L is formed between the projection 82 and the edge 26c of the recess. This gap ensures that two nozzle devices can be turned comfortably with respect to each other (and with respect to the longitudinal direction L) for joining.

(17) FIG. 3 is a perspective view of a support 2. In this case, again the projections 82 which are arranged on the receiving recess 24 (more precisely, on the wall of the receiving recess 24) can be seen. Furthermore, the recess 32, which when putting together two nozzle devices serves to receive the receiving recess 24, can also be seen. Reference sign 32 relates to recesses which serve for receiving the projections 82. In addition, recesses 34 which serve to reduce weight and also to increase stability are also provided. Here again too, the two wings which serve for grasping or for manual turning of the nozzle arrangement can be seen. A nozzle device can also be fastened easily and in particular manually to another nozzle device by means of these wings 22 (by rotation with respect to the longitudinal axis).

(18) FIG. 4 is a plan view along the longitudinal direction L (which here runs perpendicular to the plane of the drawing) of a nozzle device 1 according to the invention. Again, the projections or wings 22 which serve to turn the nozzle device 1 can be seen. In addition, the recesses 32 and 34 can also be seen.

(19) Finally, FIG. 5 is a further side view of a device according to the invention. In this view, in particular the two coupling means 6 and 8, which jointly form a bayonet-like closure, can also be seen. The coupling means 8, as mentioned above, is formed by the two projections 82, and the coupling means 6 by the recess 26 which has the oblique portion 26b, which serves for bayonet-like connection of the two nozzle devices.

(20) The applicant reserves the right to claim all the features disclosed in the application documents as essential to the invention, insofar as they are novel individually or in combination over the prior art. It is furthermore pointed out that features which taken by themselves might be advantageous have also been described in the individual drawings. A person skilled in the art will recognise immediately that a certain feature described in one drawing may be advantageous even without adopting further features from this drawing. Further, a person skilled in the art will recognise that advantages may also result from a combination of a plurality of features shown in individual or in different drawings.
