Definitions

  • the invention relates to a discharge device for one or more flowable media, which can be liquid, gaseous, powdery or powdery, pasty or similar.
  • a media stream via an inflow mouth in particular with the interposition of an inflow control valve, is to be fed to a further media stream upstream and / or downstream of a discharge opening leading to the outside, it being possible for two or more media streams to be the same medium or different media.
  • This configuration enables an intensive application of one medium to the other in the vicinity or in the area of the discharge opening under favorable pressure conditions.
  • the media of the media streams can be provided for mixing or other processing.
  • At least one, in particular gaseous, media stream can also be provided as the delivery or carrier stream for at least one further medium.
  • An inflow control valve is proportionate Far away from the merging of the associated media flows, large pressure losses can occur in particular up to the merging if this control valve, for example as a pressure relief valve, opens in a pressure-controlled manner and the last valve is up to the discharge opening.
  • the invention is further based on the object of creating a discharge device of the type mentioned, by means of which disadvantages of known solutions are avoided and with which, in particular, pressure losses of at least one medium can be avoided in a simple manner before two or more media are brought together.
  • the respective medium can be put under pressure immediately before entry into the area of merging by a lock, such as a control valve, so that when the lock is opened there is only a minimal path to the area of Must merge.
  • a lock such as a control valve
  • the associated medium can impact the other medium practically without loss of pressure.
  • the pressure of the supplied medium essentially corresponds exactly to the adjusted opening pressure of the control valve, because after its valve seat there are no appreciably pressure-effective flow paths that can cause the medium to decelerate or accelerate.
  • the area where the media are brought together can be at a greater distance from or directly adjacent to the outlet opening, for example in the area of the rear end of a nozzle cap be provided so that the media have to flow essentially only in a straight line from the merging to the outlet opening or to a swirl device for the atomization of the corresponding medium.
  • the inflow mouth or the valve opening forming it can be located on the circumference of at least one chamber or channel. If two adjacent channels touch or cross one another, for example tangentially, in such a way that their inner surfaces form a breakthrough at one point, the inner circumference thereof can be delimited by a very narrow, cutting-like edge, the flanks of which are formed directly by the inner surfaces mentioned.
  • the width of the opening is advantageously smaller than the width of one or both channels or larger than the discharge opening, and the opening forms the connection or inflow opening.
  • the inflow orifice for at least one medium surrounds a channel or a chamber for at least one further medium in a ring at least partially, so that the inflowing medium is distributed in individual flows or as a ring Total flow flows radially inwards.
  • the inflow opening can be delimited by two opposing end faces, which can expediently be closed under a control force in such a way that they form the closing surfaces of the control valve.
  • the inflow mouth can also be provided at a short distance from the closing surfaces of the control valve.
  • openings formed by the valve seat and the inflow opening can be provided axially one behind the other on an inner circumferential surface and / or radially adjacent or coaxially in the region of an end face.
  • the inflow in the area of the outlet opening e.g. to be provided in such a way that at least two media are fed to one another only in the area in which they exit directly into the open.
  • the one media stream can be fed to a coaxial core stream as a converging and therefore accelerated envelope stream.
  • the core stream is injected directly in front of the discharge opening, which conducts the sheath flow, through a slightly recessed but exiting outlet opening, so that strong swirling and atomization can take place at this outlet opening and the sheath flow tears the core flow out of the outlet opening.
  • the width of the annular channel for the sheath flow e.g. as a function of the occurring flow pressures of at least one media stream, are continuously and continuously changed.
  • means are expediently provided in order at the end of the pressure delivery of a medium with liquid, pasty and / or powder-like properties to be able to pass a cleaning stream through at least a part of the outlet channel or the discharge opening, which is expediently gaseous or is formed by air.
  • a corresponding valve in particular the control valve, is inevitably kept in an at least partially open state, as a result of which the compressible delivery or cleaning medium, which is biased in a chamber, can still flow.
  • the design according to the invention is particularly suitable for discharge devices which have at least two e.g. has coaxially combined and simultaneously operated pumps, such as thrust piston pumps, which have separate pressure or pumping chambers.
  • One pump can be designed as an air pump closer to the discharge opening, while the other pump, if necessary, delivers from an associated media store.
  • This part of the discharge device can e.g. be designed according to that according to DE-OS 37 22 469, which is referred to for further features and effects.
