Definitions

  • the invention relates to a multi-way flood valve for technical liquids, such as technical waxes, with a linear flow rate regulation for the optimal supply of points of need with the technical liquid.
  • This solution is used, among other things, for the cavity preservation of vehicle underbody assemblies.
  • EP2 740543 A2 a system for the preservation of metallic components and motor vehicle bodies by applying an anti-corrosion agent.
  • This system consists of "a tubular supply line for supplying the anti-corrosion agent to at least one control valve, which penetrates the wall of the supply line diametrically.
  • the control valve has a control shaft which is rotatably arranged in a switching tube and has a coaxial cavity.
  • the switch shaft openings are arranged in such a way that they can be brought into partial or complete overlap by turning the switch shaft.
  • the overlapping openings provide a flow path for the anti-corrosion agent from the supply line to a first flood point in a first angular position of the switch shaft relative to the switch tube and in a second angular position free the flow path to a second flood point.”
  • This solution describes a sequential release of the flow path for the anti-corrosion agent by turning the selector shaft and the resultant overlapping of the openings arranged in the selector tube and selector shaft.
  • the regulation can only take place until the opening is completely covered by turning.
  • the flow rate regulation itself is limited to the possible size of the openings in relation to the diameter of the shift shaft and shift tube. Since the amount of preservative required in the various areas within a body part varies greatly, a further system for supplying preservative with a further dimensioning of the openings would have to be arranged for each area of the body. A longer continuous regulation of the amount of preservative is not possible with this solution, since the selection of the size of the openings depends on the dimensioning of the shift tube and the shift shaft.
  • the object of the invention is to create a technical solution that will help to overcome the known deficiencies of the prior art.
  • the new solution is intended to create the possibility that a device can be used to realize several valve outlets at different times and in different outlet directions, with a longer stepless regulation of the wax flow volume being the outlet volume.
  • the multi-way flood valve initially consists of a fixed hollow shaft and a linearly displaceable control piston, on the fixed hollow shaft two spaced apart and serving to support and guide the control piston control piston bearings are arranged with guide rings and sealing rings and the control piston mounted in this way is connected to a linear drive.
  • this hollow shaft is arranged in a wax depot in the area between the bearings of the hollow shaft, which is connected to a wax supply ring line and is supplied with wax via this ring line and is thereby kept under pressure.
  • a single depot is responsible for supplying the wax supply. Due to the overpressure, the wax is immediately at the openings of the accesses and is available there and can flow into the desired accesses after opening them.
  • This through hole arranged as a wax feed hole, whereby the hollow shaft is thereby equipped with at least one access to the wax depot container.
  • This through hole which serves to supply wax to the control piston, has a rectangular cross section.
  • the through bores of the control piston for supplying wax have a round, oval or square cross-section.
  • the hollow shaft has at least one opening in the area outside of the wax depot arrangement, but in the area of the arrangement of the wax flow outlet nozzle, which is used for draining off the residual wax and for venting. This ensures that if there is any wax running back after the wax feed holes have been closed, this excess can leave the flooding system unhindered and be returned to the wax storage tank via suitable connections and lines and if there is no wax, the air present can escape.
  • the linearly movably mounted control piston is arranged in the fixed hollow shaft and has two longitudinally spaced through bores as wax feed bores, which are designed with the same rectangular cross-section in terms of shape and dimensions as the through bore (wax feed bore) of the hollow shaft.
  • the distance between the two wax feed bores of the control piston corresponds to the possible extent of the linear travel of the control piston.
  • the wax supply bore in the control piston is arranged via a through bore with the same shape and dimensions as the two spaced-apart through bores of the hollow shaft as wax supply.
  • the distance between the two wax feed holes in the hollow shaft corresponds to the possible extent of the linear travel of the control piston.
  • further bores are provided in the wall of the control piston as wax outlet bores, but each is offset on one side in the wall and in the longitudinal direction as well as on the circumference of the control piston.
  • these bores are each arranged exactly in the area of the wax flow outlet bore of the hollow shaft for the respective wax flow connection piece. Both holes also correspond in shape and dimension to the two wax flow outlet holes of the hollow shaft.
  • the wax outlet bores and the associated wax flow connection pieces are each equipped with different shapes and/or dimensions and are arranged linearly offset or offset at an angle on the outer wall of the control piston and the hollow shaft and the linear drive of the control piston is additionally equipped with a Rotary drive is equipped.
  • this linear/rotary drive is controlled in connection with a computer-aided evaluation unit.
  • the wax connection pieces on the fixed hollow shaft could be arranged on the same side, only linearly offset, and the associated wax outlet bores of the control piston could also be arranged on one side linearly offset on the control piston.
  • the multi-way flood valve according to the invention is intended to be used for a cavity preservation system for motor vehicle bodies and for this purpose to supply technical wax liquid at the same time to various connection points on the body for cavity flooding with liquid wax.
  • the multi-way flood valve according to the invention has a linear flow rate regulation.
  • This multi-way flood valve is in accordance with Figures 1 to 5 of a fixed hollow shaft 1 and a linearly displaceable control piston 2 arranged therein.

  • the through hole 6 serving to supply wax to the control piston 2 has a rectangular cross section.
  • the hollow shaft 1 is equipped with an opening 7 for the residual wax drain in the area outside the wax depot arrangement 4, but in the area where the wax flow outlet connection 9.1/9.2 is arranged.
  • the control piston 2 which is linearly movably mounted in the fixed hollow shaft 1, is equipped with two spaced-apart through bores as wax feed bore 10 with the same cross-section in shape and dimensions as the through bore (6) of the hollow shaft.
  • the distance between the two wax feed bores 10 of the control piston 2 corresponds to the possible linear travel of the control piston 2.
  • the cross sections of the bores 10 and 6 are rectangular, advantageously square. However, they always have the same cross-section and the same dimensions.
  • Another bore 11.1 serves as a wax outlet bore and is arranged on one side in the wall of the control piston, and there exactly in the region of the wax flow outlet bore 8 of the hollow shaft for the wax flow connection piece 9.1.
  • a second hole as a wax outlet hole 11.2 is arranged for the wax flow connector 9.2 of the hollow shaft 1 in the wall of the control piston 2, but offset by the amount of the possible linear travel of the control piston 2 to the hole 9.1.
  • Both holes 9.1 and 9.2 correspond in shape and dimension to the two wax flow outlet holes 8 of the hollow shaft.
  • the wax outlet bores 11.1, 11.2 arranged opposite one another and the associated wax flow connection pieces 9.1, 9.2 can always be equipped in the same way but with different shapes and/or dimensions.

  • This solution offers the advantage that with a depot for the technical liquid and a hollow shaft with linearly movable control pistons, several connection areas for the supply of the technical liquid can be supplied with the same quantity and with the same pressure. Furthermore, the excess technical liquids are returned to the depot for these liquids. Thanks to the linear drive and the identical bore dimensions and shapes of the bores in the wax flow connection sockets 9.1 and 9.2 and the wax outlet bores 11.1 and 11.2, stepless regulation of the amount of wax as a technical liquid can be regulated at short notice.
