Definitions

  • FIG. 1 shows the configuration of the nozzle arrangement in a known application device.
  • a displaceable in the longitudinal direction of the axis a, at its tip conical nozzle needle 1 cooperates with a circular outlet channel 3, so that the passage cross section 5 determining the liquid flow has the shape of a circular ring.
  • the viscous liquid is fed to a chamber 7 of a body 6 of the application device via a channel 8 and leaves the chamber 7 via the outlet channel 3.
  • the disadvantage of an application device according to Figure 1 is the heavy wear at the inlet end of the outlet channel. Since the annular passage cross section has a relatively long boundary line in relation to the cross section 5, the cross section / edge ratio of the passage cross section is very small. This means that the liquid also has a relatively high flow velocity in the edge zone of the passage cross section, which results in high abrasion and wear on the edge 4 of the outlet channel, even then; if the outlet pipe is lined with a ring 9 made of hard special material at this point. As a result of this wear, the average cross section and thus the amount applied by the application device per unit of time, that is to say the flow, of the viscous liquid changes for a given position of the nozzle needle 1.
  • the invention has for its object to develop an application device of the type mentioned, in which the risk of clogging of the flow path through deposits is eliminated.
  • Another advantage of the application device according to the invention is that the passage cross-section is adjusted by a rotary movement of the adjusting piston. This is drive-related and can be better controlled with regard to the accuracy of the setting, which is very advantageous for control purposes.
  • the application device is designed in such a way that there is a large cross-sectional edge ratio at all points of the flow path and that, especially with a small stroke of the nozzle needle, a linear relationship between the stroke and outlet volumes is achieved.
  • the nozzle groove is preferably designed so that its width for all cross sections perpendicular to the longitudinal direction of the nozzle groove is not less than at any other point in the cross section in question.
  • the cross-section of the nozzle groove in the radial direction can be, for example, V-shaped, semicircular or in another suitable manner.
  • the nozzle arrangement according to FIGS. 2a and 2b comprises a cylinder 62 which is arranged in a counterpart designed as a cylinder block 66.
  • An adjusting piston 61 which can be rotated about the axis a is arranged in this cylinder.
  • the viscous liquid is fed in at point A and arrives via an inlet line 64, which penetrates cylinder block 66, into an annular nozzle groove 65, which is machined in the circumferential direction into the jacket wall of adjusting piston 61.
  • the outlet line 63 opens at the level of the nozzle opening in the cylinder 62. It is offset in the circumferential direction from the Neuetwa line 64 by the angle ⁇ . In the exemplary embodiment shown, the offset is approximately 90 degrees.
  • the nozzle opening has a practically constant cross section, which is, however, not absolutely necessary.
  • adjoining angular section is the nozzle opening with a changing cross-section formed, this change can be achieved by a converging side walls 65a and 65b and / or by varying the depth of the nozzle groove.
  • the cross section of the nozzle groove 65 in the radial direction can be, for example, V-shaped, semicircular or in another suitable manner.
  • the cross-section mentioned is dimensioned so that the cross-sectional edge ratio is as large as possible.
  • the stroke-volume characteristic can be influenced in the desired manner by selecting the angle alpha, the radial depth and the axial width of the nozzle groove. Thanks to the design of the passage cross-section that determines the passage volume of the viscous liquid, an approximately linear stroke-volume characteristic can be achieved over a wide range.
  • Figures 2a and 2b show the nozzle arrangement in the position with the largest possible opening. To reduce the opening, the adjusting piston 61 is rotated clockwise in FIG. 4b.
  • basically two or more nozzle grooves 65 working in parallel with one another in the circumferential direction of the adjusting piston and / or one above the other in the axial direction of the adjusting piston can also cooperate with corresponding inlet and outlet lines, insofar as the peripheral / taking into account that for the adjustment required angle of rotation or the axial space allows this without collision.
  • the embodiment according to FIG. 2 can be modified such that the nozzle groove is not arranged in the wall of the adjusting piston 61, but in the wall of the cylinder 62. However, the outlet line or the inlet line must then run through the adjusting piston 61. This can be done in that the outlet line or the inlet line is connected to an annular groove in the adjusting piston, which in turn is connected to the nozzle groove via a channel or an axially extending longitudinal groove, the connection opening between the longitudinal groove or the longitudinal channel and the Nozzle groove is adjusted in size.
  • FIGS. 3a and 3b show a modification of the embodiment according to FIG. 2, which is characterized by a particularly simple design. To the extent that the same reference numerals as in FIG. 4 are used in FIGS. 3a and 3b, these are the corresponding parts.
  • the peculiarity of this embodiment is that the outlet line 63 is arranged centrally in the adjusting piston 61. This considerably reduces the dimensions of the cylinder block 66. The outlet line 63 has practically no corners in which deposits could possibly still form to a small extent.
  • the viscous liquid enters the cylinder block 66 via the inlet channel 64 and is connected via the nozzle groove 65 to the horizontal bore 63a, which opens into the central outlet line 63.
  • a further bore 80 can be provided in the nozzle arrangement according to FIG. 3 in relation to the inlet line 64 and is connected hydraulically to the inlet line 64.
  • the material in this bore does not flow, but merely exerts pressure on the adjusting piston 61, causing the adjusting piston to be tilted avoided and the torque required to rotate the adjusting piston reduced,
  • FIG 3a is also indicated how the other parts of the application device can be designed.
  • a gear 71 is arranged, which is driven by two motors 72, each via a pinion 73.
  • the motors 72 are fastened to a supporting part 74 not participating in the rotation, and the adjusting piston 61 is rotatably mounted in this part 74.
  • a position measuring arrangement for the position of the adjusting piston 61 is indicated at 75. It can be used to measure the actual value of the nozzle opening and thus, under other conditions, the actual value of the liquid flow.
