Definitions

  • the present invention relates to a valve for metered delivery of liquids.
  • Valve assemblies for pressurized fluid containers, such as aerosol containers, are known in various embodiments.
  • the volume to be dispensed is displaced by a liquid gas.
  • the liquid is expelled by the gas pressure.
  • the product is sealed off from the environment in the housing, it comes into contact with the propellant gas.
  • the invention has for its object to provide a metering valve for a fluid container in which the liquid can be dispensed without the addition of propellant in a metered amount.
  • the input channel is arranged in the shaft body, that upon actuation of the valve, the metering region is connected to the first volume through the input channel.
  • the output channel is arranged in the shaft body, that upon further actuation of the valve, the output channel is connected to the first volume.
  • valve housing Such an arrangement makes it possible to receive a defined amount of liquid in the valve housing, which can then be dispensed in one dose.
  • This filling of the valve housing can be provided by a low hydraulic pressure of a two-chamber system.
  • the amount of liquid is from the Volume of the metering determined, which in turn is determined by the dimensioning of the components, in particular the valve housing, the valve piston and the shaft body.
  • a particular advantage of the valve according to the invention is that the product to be dispensed is discharged and atomized purely mechanically.
  • the atomization permeability can be influenced by using different spring forces.
  • a propellant gas does not have to be incorporated in the fluid and thus is not present in the valve.
  • the product in a hermetically sealable two-chamber system, the product is not only protected from the atmosphere, it also does not come in contact with other substances, e.g. a propellant.
  • the production costs are reduced by dispensing with propellant.
  • the metering region between valve piston and inlet valve comprises a first partial volume and below and in continuation of the inlet channel of the shaft body, a second partial volume, which are interconnected.
  • the upper end of the valve housing has an upper seal. Through an opening of the upper end and the upper seal of the shaft is guided. The upper seal seals both on the shaft between the valve housing and the environment as well as between the interior of the fluid container and the environment.
  • the upper end is an insert which sits on an inner stage of the valve housing.
  • the insert is held securely in a defined position.
  • the insert ensures sufficient stability during the crimping process.
  • the insert part has a hollow cylindrical section which extends beyond the upper inner step into the valve housing and into which the shaft body is sealingly guided.
  • the insert serves to guide the shaft and the reduction of the first volume, whereby unused dead space is reduced.
  • the opening of the insert has a larger diameter than the opening of the upper seal.
  • the sealing effect of the upper seal is increased and, secondly, liquid can pass from the input channel into the first volume or from this into the output channel of the shaft, if the upper seal has been passed by a corresponding opening upon actuation of the valve ,
  • a lower portion of the shaft body is guided in the piston channel of the valve piston, in which the second partial volume is defined.
  • the shaft body at its end facing the valve piston on a cylindrical cavity which defines the second sub-volume and in which an upper portion of the Ventilkobens dips.
  • a circumferential reduction of the inner diameter of the piston channel and a circumferential thickening of the lower portion of the shaft body limit the relative movement between the valve piston and the shaft body and thus define the size of the second partial volume.
  • a circumferential thickening of the valve head and a circumferential projection of the shaft body pointing into the cavity delimit the relative movement between the valve head and the shaft body and thus define the size of the second partial volume. Furthermore, it prevents the upper Section of the valve piston emerges from the hollow of the shaft body and the components wedge in the valve body.
  • At least one sealing means is arranged on the circumference of the valve head and / or on the circumference of the shaft body, which sealingly cooperates with the inner wall of the valve housing.
  • the sealing means is designed as a circumferential sealing lip or as a sealing ring.
  • the inlet valve has a lower seal facing the inlet opening of the valve housing, which increases the sealing effect in this area.
  • the inlet valve may also be referred to as a plug which closes the lower inlet opening
  • the inlet valve extends at least with an upper portion in the piston channel of the valve piston.
  • the inlet valve of the leadership of the lower spring and the limitation of the vertically executable movement of the shaft body is used.
  • the shaft has at least one lower transverse channel, which is connected to the input channel and can be connected to the first volume when the valve is actuated.
  • the shaft has at least one upper transverse channel, which is connected to the output channel and can be connected to the first volume upon actuation of the valve.
  • the inlet channel and outlet channel are separated from each other in the axial direction of the shaft body.
  • the valve housing has an outer stage, which rests in the inserted state of the valve to a part of the fluid container. This allows the stability of the valve axially in the direction of a container in which it can be used even further increase.
  • valve for the metered delivery of liquids is inserted into a valve plate 10 which is attached via an outer seal 12 to a fluid container, not shown.
  • the valve disk 10 has a base 13 which merges toward the center into a cylindrical portion 14 facing away from the fluid container and pointing upwards.
  • a valve housing 20 is inserted, which extends down into the fluid container.
  • a plurality of spaced indentations 15 are arranged, which engage behind a circumferential outer step 25 of the valve housing 20, whereby a depression of the valve is prevented in the fluid container.
  • the valve is held in place by a lid portion 16, which is a horizontally extending continuation of the cylindrical portion 14 and has an opening 11.
  • the opening 11 in the lid portion 16 forms the opening of the fluid container.
  • the valve housing 20 is substantially cylindrical and, in addition to an upper inner stage 24 belonging to the outer step 25 in the upper region, has two further stepped tapers. These are in a lower region of the valve housing 20, a central inner stage 26 and a lower inner lower step 27. At the lower inner stage 27, at a lower, facing the interior of the fluid container end of the valve housing 20, an input port 21 is defined. At the top, ie at the container end, the valve body is closed by an insert 22 which rests on the upper inner stage 24. The Insert 22 and the upper seal 23 arranged thereon are clamped between the upper inner stage 24 and the lid portion 16 of the valve disk 10. The insert 22 and the upper seal 23 have an opening 11 of the valve disc 10 corresponding opening, wherein the diameter of the opening of the insert 22 is slightly larger than that of the upper seal 23rd
  • a shaft body 40, a valve piston 30 and an inlet valve 50 hereinafter referred to as plug 50, arranged.
  • the plug 50 and a lower seal 51 arranged underneath are guided in the valve housing 20 above the lower inner stage 27 and are at this stage on actuation of the valve.
  • the plug 50 is raised.
  • the plug and the seal have a diameter which is smaller than the inner diameter of the valve housing 20 in this area.
  • the diameter of the plug 50 and the lower seal 51 are selected so that the plug 50 sealingly abuts the lower inner stage 27 upon actuation of the valve and the inlet opening 21 closes.
  • channel-like recesses may also be provided on the inner circumference of the valve housing 20 or on the circumference of the plug 50 and the lower seal 51 for this purpose.
