Definitions

  • the invention relates to an adjustable atomizer nozzle for a hand-operated liquid atomizer of the type specified by the preamble of claim 1.
  • the holding bush, the swirl insert, the valve pin and the return spring result in separate assembly parts which only change their mutual influence on the functioning of the check valve when the nozzle nut is also included experienced assembly of such a nozzle on a threaded attachment of an atomizer housing provided for its arrangement.
  • the assembly is made more difficult by the return spring, in that the pretensioning exerted on the valve pin is obtained only with an interaction of its valve head with the valve seat formed on the housing side at the mouth of the outlet pressure line of the atomizer.
  • the invention characterized by the claims solves the problem of designing an adjustable atomizer nozzle of the type specified in such a way that it can be arranged more easily on the threaded attachment of an atomizer housing provided for this purpose by an uncomplicated assembly of the individual nozzle parts.
  • the advantages that can be achieved with the atomizer nozzle according to the invention are essentially that the swirl insert, the valve pin and the return spring are now combined to form an assembly group in which the preload on the return spring exerted on the valve pin by the interaction of its stop collar with the retaining projection of the Insert piece is braked.
  • This assembly group which can at the same time be easily completed, can therefore be plugged together with the holding sleeve without great difficulty and then screwed onto the threaded attachment of an atomizer housing by means of the nozzle nut.
  • the atomizer nozzle according to the invention is preferably provided for a manually operated liquid atomizer of the design according to DE-PS 3 245 493.
  • the liquid stored in a liquid container is brought into operation by actuating a piston pump by means of a handle lever via an outlet pressure line 1 of the atomizer housing 2, at the mouth of which a check valve which can be actuated by the outlet pressure of the liquid and which is designed to generate an adjustable spray jet is arranged.
  • the atomizer housing 2 is formed in one piece with a threaded shoulder 3 which is axially identical to the mouth of the pressure line 1, and a nozzle nut 4 can be screwed onto its external thread.
  • the nozzle nut 4 is essentially pot-shaped and has a passage opening 5 on the bottom for a spray jet of the liquid, which is formed by the nozzle 6 of a nozzle disk 7.
  • the nozzle 6 can also have a design integrated with the nozzle nut 4, with which the nozzle disk 7 is then not present.
  • a holding bushing 8 is axially inserted into the threaded shoulder 3.
  • the holding bush 8 is an injection molded part made, for example, of polyethylene, on which a stop collar 9 and a cover part 10 are integrally formed.
  • the stop collar 9 resting against the end face of the threaded shoulder 3 is formed with a sealing lip which is effective with respect to the nozzle nut 4.
  • the cover part 10, which can also be a separately manufactured component for an alternative design of the retaining bush 8, but then still to be firmly connected to the retaining bush, has one the mouth of the pressure line 1 through-hole 11 with the same diameter, which at its mouth forms a valve seat 12 for the valve head 13 of a valve pin 14.
  • valve seat 12 can also be formed directly at the mouth of the pressure line 1.
  • the holding sleeve 8 is then provided at its end facing away from the cover part 10 with a through hole 15, via which a swirl insert 16 can be axially inserted into the holding sleeve.
  • the swirl insert 16 is cup-shaped. At the bottom of its cavity, which is designed as a blind hole 17, a return spring 18 is supported to complete the check valve which can be actuated by the outlet pressure of the liquid and which prestresses the valve head 13 of the valve pin 14 against the valve seat 12.
  • the valve-side end of the blind bore 17 is enlarged in diameter and at the same time narrowed by a radial retaining projection 19 which is provided for cooperation with an annular stop collar 20 of the valve pin 14.
  • the stop collar 20 has a larger diameter than the valve head 13 and is dimensioned such that an axial guidance of the valve pin 14 on the swirl insert 16, which is under the pretension of the return spring 18, is obtained at the same time.
  • valve pin 14 is first inserted together with the return spring 18 into the blind hole 17 of the swirl body insert 16 for an arrangement which can be derived from the illustration in FIG. 1, the stop collar 20 is counter-tensioned by the return spring 18 pressed the retaining projection 19 and thus braked the bias of the return spring until this assembly group is then completed with the retaining sleeve 8 in the further completion of the nozzle.
  • the swirl insert 16 is also a preferably injection-molded part made of polyethylene and has six axially parallel projections 21 on its outer surface, with which, in cooperation with the surrounding wall of the holding bushing 8, individual axially parallel passage channels are formed for the liquid brought in from the pressure line 1.
  • the liquid is passed on via these passage channels and by means of the push-through hole 15 to a swirl groove 22, which is designed to cooperate with the nozzle 6 in the end face of the swirl body insert 16 resting against the nozzle disk 7.
  • the projections 21 extend only over a partial length of the swirl insert 16 and result in a slightly larger diameter for an enveloping circle compared to the diameter of the through hole 15 of the holding bushing 8.
  • the assembly group consisting of the swirl insert 16, the valve pin 14 and the return spring 18 can therefore be expanded with the holding bush 8, so that it is then only necessary for an adjustable arrangement of the nozzle on the threaded attachment 3, this whole in the threaded attachment insert axially and screw with the nozzle nut 7 completed with the nozzle nut 4 on the threaded shoulder 3.
  • FIG. 1 the individual parts of the nozzle are shown in the relative position assumed when using the liquid atomizer.
  • the spray jet emerging from the nozzle 6 of the liquid supplied via the pressure line 1 can be changed because, with the intermediary of the swirl insert 16, the biasing force of the return spring 18 acting on the valve pin 14 for influencing the adjustment path of the Valve pin is changed accordingly.
  • the blind bore 17 of the swirl insert 16 now has a shorter length than the axial displacement of the valve pin 14, then the pressure line 1 can also be completely shut off with this adjustment of the nozzle nut 4.
  • the nozzle nut 4 only has to be screwed onto the threaded shoulder 3 from the relative position shown in FIG.
