Definitions

  • the invention relates to a discharge device for a flowable medium with a discharge sleeve, at one end of a discharge opening for discharging the medium is provided, and provided in the discharge closing pin, which is longitudinally displaceable relative to the discharge and through which the discharge opening is closed.
  • Discharge devices with such designs are known.
  • the disadvantage of you is that usually a high pressure medium within the discharge sleeve rests before the locking pin releases the discharge opening. This pressure results in a spray when opening, which should be avoided depending on the application.
  • the object of the invention is to develop the known from the prior art discharge devices, in particular with regard to an improved spray pattern.
  • a generic discharge device wherein the locking pin has an outwardly facing cylindrical portion and the discharge sleeve has an inwardly facing cylindrical portion, wherein the cylindrical portions form a transition fit or a tight clearance and wherein in the cylindrical portion of the locking pin and / or the discharge sleeve, a pressure-reducing and / or media flow-reducing effective geometry is provided.
  • the effective geometry is achieved in particular by a configuration with a small cross section through which the medium must flow. It thereby limits the liquid flow. This is of particular relevance for media for application to an eye, since a strong spray jet caused by a large liquid flow is undesirable in this application.
  • the effective geometry provided according to the invention represents an advantageous and structurally simple solution for reducing the liquid flow. This is particularly advantageous in discharge devices whose discharge openings are opened as a function of a medium pressure. It is particularly advantageous if a diffuser adjoins the media-flow-reducing geometry, in which the increased pressure is reduced again.
  • the embodiment with cylindrical sections ensures that the effect of the effective geometry does not depend on the relative position of the closing pin to the discharge sleeve, as would be the case for conical sections, the distance is also changed by an axial position change.
  • the closing pin is longitudinally displaceable in response to a fluid pressure of the medium in a pumping chamber of a pumping device of the discharge device and closes at a fluid pressure of the medium below a predetermined Boundary pressure the discharge opening.
  • the inventive design is particularly useful because the high pressure required for the relative displacement of the locking pin increases the risk of a problematic spray pattern.
  • At least one media channel is provided in the cylindrical section of the closing pin and / or the discharge sleeve.
  • a media channel represents a very simple form of a knitting geometry.
  • the media channel is preferably provided on the cylindrical portion of the locking pin, since then demolding during manufacture is easier to implement. In the simplest case, the media channel extends axially parallel to the direction of displacement of the locking pin.
  • the media channel extends helically.
  • Such extension leads to two advantages. On the one hand, a long media channel can be realized despite only short cylindrical sections.
  • the media channel with an outlet direction with a tangential component in interaction with a subsequent chamber in front of the outlet opening at the same time has the effect of a diffuser, which reduces the pressure and the speed at the exit from the outlet opening.
  • the closing pin is operatively connected to a pressure plate actuated by the internal pressure, wherein the closing pin is preferably formed integrally with the pressure plate.
  • a pressure plate makes it possible to achieve the conflicting objectives of displacement of the locking pin with only a small pressure medium on the one hand and the application of force to the closing pin in the closing direction with a high spring force.
  • the pressure plate leads through its large area that the spring force counteracting Opening force is already achieved by low pressure. This is also useful for improving media output.
  • the pressure plate surface is preferably larger than the area of the discharge opening for this purpose by at least a factor of five, preferably by a factor of ten.
  • the pressure plate consists at least partially of an elastic material, preferably of a material with an E-modulus below 1 kN / mm 2 , in particular with an E-modulus below 0.5 kN / mm 2 .
  • the elasticity causes short-term pressure peaks of the media pressure are intercepted by the pressure plate. This leads to an improved opening behavior of the discharge.
  • the combination of an effective geometry according to the invention with an elastic pressure plate has proven to be very suitable for ensuring an advantageous spray pattern.
  • Figs. 1 and 2 show a section 10 of a discharge device according to the invention in a partially sectioned perspective view and a partially sectioned side view.
  • the section 10 comprises a discharge sleeve 20, which is formed in the illustrated embodiment in one piece with an otherwise not shown housing of the discharge, and arranged in the discharge sleeve 20 closing pin 30, at the lower end of an integrally formed pressure plate 40 is connected.
  • the discharge sleeve 20 has at its upper end to a discharge opening 22, can escape through the medium in the use of the discharge.
  • This discharge opening 22 is closed in the non-actuated state of the discharge by a arranged at the upper end of the locking pin 30 sealing portion 32.
  • the closing force is applied by a valve spring, not shown, which presses together the unit of closing pin 30 and pressure plate 40 in the direction of 2.
  • a discharge operation is triggered by the pressure in a gap 50 between the discharge sleeve 20 and the unit of locking pin 30 and pressure plate 40 is increased by means not shown, in particular by a pump.
  • This increased pressure acts in a partial area 50a on the pressure plate 40, wherein due to the comparatively large area of the pressure plate 40 even a little increased pressure causes a significant opening force in a direction opposite to the direction 2.
  • This opening force causes a relative displacement of the locking pin 30 relative to the discharge sleeve 20 and thus opening of the discharge opening 22nd
  • the discharge sleeve 20 and the closing pin 30 have cylindrical partial sections 20a, 30a adapted to one another.
  • the outer diameter of the cylindrical portion 30a of the locking pin 30 and the inner diameter of the cylindrical portion 20a of the discharge sleeve 20 form a tight clearance fit.
  • a helical groove 34 is provided which forms a channel 34 for the escaping medium. Due to the tight clearance, it is the medium only through this groove 34 possible to reach from the intermediate space 50 to the discharge opening 22.
  • the groove is provided in the discharge sleeve-side cylinder portion instead of in the cylinder portion of the locking pin.
  • other shapes are possible, in the simplest case e.g. straight and aligned in the longitudinal direction of the locking pin grooves.
