Definitions

• This invention relates to a gasket arrangement
• a gasket arrangement comprising a gasket which is intended to be applied into a groove made along an edge 5 of a heat exchanger plate and which on its side directed to the mentioned edge is provided with projections arranged at a distance from each other - seen in the longitudinal direction of the gasket - which projections are made in one piece with the gasket and arranged to hold the gasket in the groove, the projections coope- 10 rating with a holding part.
• the purpose of the present invention is to bring about a new gas ⁇ ket arrangement which is not connected with the drawbacks with the above mentioned gasket arrangements but which still makes the manufacture of gaskets possible in until now a usual way without essential increase in price of necessary equipment for the manu ⁇ facture.
• gasket arrangement of the common kind mentioned by way of introduction comprising a gasket with projections on its side directed to the edge of the heat ex ⁇ changer plate, which gasket arrangement is characterized in that the holding part comprises at least one projection that is direc ⁇ ted to the gasket and is positioned at a distance from the gasket projection seen in the longitudinal direction of the gasket, and besides that the gasket projection and the projection are made in that way that when the gasket is in place in the groove on the one side of the heat exchanger plate, the gasket projection is on the same side but the projection is on the opposite side of the heat exchanger plate.
• Fig. 1 shows a part of a gasket intended to be included in a gas- ket arrangement according to the invention
• Fig. 4 shows a cross section along the line IV-IV of Fig. 3,
• Fig. 5 shows a part of a gasket according to a modified embodi- ment
• Fig. 6 shows a part of a heat exchanger plate with a gasket pro ⁇ vided with a holding part according to another embodiment
• Fig. 7 shows a cross section along the line VII-VII of Fig. 1, and
• Fig. 8 shows a similar cross section as in Fig. 7 but taken from a slight modified embodiment.
• a part of a gasket 1 is disclosed that has a projection 2 made in one piece with the gasket. There are similar projections on several places along the gasket (not shown).
• the gasket projection 2 carries two other projections 3 and 4, the free ends of which are directed towards the gasket 1.
• the projections 3 and 4 are connec ⁇ ted with the gasket projection 2 by a bridge 2A and are positioned on each side of the gasket projection 2 in essentially the same plane as this one and the gasket.
• Fig. 3 there is shown a portion of an edge part of a heat ex ⁇ changer plate 5 consisting of a relatively thin plate. The edge itself is marked with 6. Parallel with the edge 6 there is made a groove 7 in the plate, into which a gasket 1 according to Fig. 1 is applied.
• the edge part of the plate is corrugated which is apparent from Fig. 4 so that valleys 8 and ridges 9 extend parallel and trans ⁇ versely to the gasket groove 7 on the same side of the plate as that one. Corresponding valleys and ridges are formed on the other side of the plate. Thus, a corrugating valley on one side of the plate corresponds to a corrugating ridge on the other side of the plate and vice versa.
• FIG. 5 there is shown a modification of the embodiment shown in Figs. 1-4.
• the figure discloses a part of a gasket 1 which is provided with projections 10, 11 made in one piece with the gasket.
• the ends of the projections 10, 11 are connected with each other by a bridge 12 which extends parallel with the gasket 1.
• a projection 13 Between the gasket projections 10, 11 and in one piece with the bridge 12 there is made a projection 13, the free end of which is directed to the gasket 1.
• the bridge 12 and the projection 13 constitute a holding part for the gasket projections 10, 11.
• OMPI holding part 15 is forcing the gasket projection 14 down into the corrugating valley 8.
• the middle pro ⁇ jection 16b of the holding part 15 is provided with a protuberance 18 which cooperates with a corresponding recess 19 on the upper side of the gasket projection 14 (see Fig. 7).
• Fig. 8 there is shown a modification of the gasket arrangement according to Figs. 6 and 7.
• the gasket 1 is provided with a pro- jection 20 that cooperates with a holding part 21, which in simi ⁇ larity with the holding part 15 according to Figs. 6, 7 comprises a bridge and three projections.
• the middle projection of the holding part 21 is fastened to the gasket projection 20, prefer ⁇ ably by vulcanization.
