Definitions

  • the invention relates to a valve assembly for aerosol container with a valve plate, a valve assembly comprising at least one discharge element, a sealing ring and a compression spring, and having a receiving space for the valve assembly.
  • the receiving space has on its upper side a mounting opening for insertion of the valve arrangement.
  • the mounting opening of the receiving space connected to the valve disk is closed by a surface having a passage opening for the discharge element.
  • the sealing ring is clamped between this surface and an annular seating surface surrounding the mounting opening of the receiving space and closes an opening of the dispensing element when the dispensing element is axially supported on the sealing ring under the action of the compression spring.
  • the delivery element is a stem or actuator.
  • the receiving space On its underside, the receiving space has a connection for a standpipe or other specific components, which establish a fluid connection with the interior of the aerosol container on.
  • valve assembly with the features described is out DE 38 07 156 A1 known.
  • the valve plate of the known valve assembly is made of plastic and has an integrally formed receiving space in which the valve assembly is used.
  • the receiving space is then closed by a plastic cap, which is sealed to the valve plate by welding.
  • the sealing ring engages in a circumferential annular groove of a stem when the stem is axially supported on the sealing ring under the action of the compression spring. Above the annular groove, the diameter of the stem is larger than the diameter of a distal portion.
  • the stem is moved so far into the interior of the receiving space depressed until the formed with a small diameter portion of the stem dips into the passage opening of the plastic cap and thereby forms an annular passage cross-section for the propellant.
  • the fluid flows through a gap between the seal and the stem in the receiving space, flows through the receiving space and from there into the interior of the aerosol container. Since the stem has a small diameter by design and is guided within the receiving space with a sliding fit, the flow path is subject to a noticeable pressure loss, which adversely affects the filling speed.
  • Out JP H09240761 A is a valve assembly for aerosol container with the features described above known.
  • gas channels are arranged on the outer circumference of the equipped with the valve assembly receiving space extending from the underside of the valve disk to the periphery of the sealing ring, wherein between the discharge element and the discharge element surrounding passage opening, a gap is provided, which at an end face of the Seal ring ends and form with the gas channels a flow path for pressure filling a sealed with the valve assembly aerosol container.
  • the receiving space for the valve assembly is disposed in a valve housing which is mountable in a mounting opening on the underside of the valve disk. An assembly of the valve assembly by an accessible at the top of the valve disc assembly opening is not possible.
  • the object of the invention is to provide a valve assembly for aerosol containers, which can be mounted fully automatically and with only a few assembly steps. Furthermore, the flow path within the valve assembly at a pressure filling release a large flow cross-section and be sealed again after the pressure filling.
  • gas channels are arranged on the outer circumference of the receiving space, which extend from the underside of the valve disk to the periphery of the sealing ring and together with a gap which is provided between the discharge element and the passage opening surrounding the discharge element and ends at an end face of the sealing ring Form flow path for pressure filling of an aerosol container sealed with the valve assembly.
  • a high pressure builds up on the end face of the sealing ring.
  • the dispensing element may remain in the position in which the opening of the dispensing element is closed by the sealing ring. Since the sealing ring is supported by the discharge element on the underside, the sealing ring further seals the receiving space and prevents blowing agent from entering the receiving space.
  • the sealing force between the end face of the sealing ring and the adjacent surface decreases due to the force acting on the end face of the sealing ring filling pressure.
  • By acting on the end face of the sealing ring filling pressure deforms the sealing ring, wherein a flow path between the end face of the sealing ring and the receiving space occluding surface is released.
  • the propellant flows radially over the entire circumference of the sealing ring and is passed through the immediately adjacent gas channels in the interior of the aerosol container.
  • the sealing ring is again with a sufficient sealing effect on the cover surface.
  • the sealing effect also contributes to the fact that the internal pressure of the filled aerosol container acts on the peripheral edge of the sealing ring and reinforces a preload of the sealing ring.
  • the described filling relates in particular to the filling with propellant.
  • the product can be supplied.
  • the dispensing element is pressed down so that the opening of the dispensing element is fluidically connected to the receiving space of the valve assembly and the filling with the product by the dispensing element and its opening through the receiving space and a lower side connected riser can be done.
  • valve assembly also allows, for example, a pressure filling with propellant when the dispensing element is pressed down until the opening of the dispensing valve communicates fluidly with the receiving space of the valve assembly.
  • the flow path of the propellant in this case extends over both the gap, sealing ring and gas channels and via the discharge element, the opening through the receiving space and a riser connected at the bottom.
  • the mounting opening of the receiving space is accessible at the top of the valve disk and the passage opening for the discharge element is arranged in a cover which is fastened to the valve disk and closes the mounting opening of the receiving space.
  • the receiving space of the valve assembly can from the valve disk outside with the valve assembly, ie at least one discharge element, a sealing ring and the compression spring, be fitted. Subsequently, the receiving space must be closed only by applying the lid.
  • the constructive embodiment of the invention described enables a simple and fully automated assembly, which is characterized by a small number of assembly steps.
  • the gas channels provided for pressurizing an aerosol container closed with the valve assembly extend from the underside of the valve disk to a surface of the cover.
