Definitions

• the invention relates to a flat gasket.
• a design is e.g. from DE 10 2005 025 942 Al known.
• the flat gasket according to the invention has the advantage that, by providing at least one second and at least one third through-bore, which are formed with mutually different diameters in the flat gasket and which for the passage of
• a pair of second through-holes of the same diameter and a pair of third through-holes of the same diameter is provided, wherein the diameter of the pair of second through-holes is different from the diameter of the pair of third through-holes.
• the pairs of through holes with different diameters are arranged in such a way in the flat gasket, that an insert of the gasket is permitted in only one specific position.
• the pairs are arranged in such a manner on the flat gasket, that each through hole as the nearest neighbor each has a through hole of the same diameter and a through hole of different diameter.
• the outer contour of the gasket is formed at least at one portion larger than the outer contour z.
• Valve allow surrounded by a circumferential collar or a closed around the through hole running bead.
• the main body is covered with an elastic material, for. B. preferably rubber coated on both sides.
• a holding device is preferably provided on the second through-holes, which consists of a pair of projecting retaining clips which project from the opening of the second through-hole.

• FIG. 4 shows a sectional view through a section of the flat gasket according to the invention.
• Fig. 1 shows a plan view of the flat gasket 1 according to the invention, which for sealing a
• the flat gasket 1 is constructed from a substantially plate-shaped base body 2, the z. B. may be made of a rubber-coated substrate.
• a first through hole 3 is provided in this embodiment, which serves in the assembled state of the flat gasket 1 to allow a connection of the valve by means of a connection or a conduit.
• a circumferential collar 4 or the annular bead on the plate-shaped base body 2 is provided.
• the first collar 4 has a closed course and is preferably produced by forming the base body 2.
• the plate-shaped base body 2 further comprises a pair of second through holes 6, which serve to seal the flat gasket 1 by means of suitable fastening means, for. B. by means of screws, to the valve (not shown) to attach.
• the second through-holes 6 have the same diameter and are arranged with mirror symmetry on the flat gasket 1 with respect to an axis A which divides the flat gasket 1 into two halves.
• a third through hole 5 is further provided in the plate-shaped main body 2 of the flat gasket 1, which has a smaller diameter than that of the second through-hole 6.
• the third through hole 5 is intended to receive a pin, which is provided on the valve or valve housing, and which serves as anti-rotation. Also, by providing the third through-hole, an unambiguous positioning of the flat gasket on the valve is determined, so that a wrong fit is excluded.
• the plate-shaped main body 2 of the flat gasket 1 has an outer contour 8, which substantially corresponds to the outer contour 9 of the valve housing, which is indicated by the dashed line in Fig. 1.
• the outer contour 8 of the flat gasket 1 is provided in two sections with a projection 10 with respect to the contour 9 of the valve housing. This makes it possible that in a mounted state of the valve housing, a part of the gasket 1 is visible and thus it is not forgotten during assembly and can be checked whether the gasket 1 is mounted.
• Fig. 2 is a side view of a power regulator valve 7 is shown, wherein the flat gasket 1 according to the invention is already pre-assembled thereto.
• the valve housing 11 has an outer contour 9, which substantially coincides with the outer contour 8 of the plate-shaped main body 2 of the flat gasket 1, but deviates in two sections thereof. Since the flat gasket 1 according to the invention is formed with a projection 10 with respect to the valve housing 11, the flat gasket 1 visibly bulges even in the installed state of the valve 7.
• the housing 11 of the power regulator valve 7 is further provided with a pair of opposite through-holes 12 which are in position with the second
• Through holes 6 of the gasket 1 match when the gasket 1 is mounted on the valve housing 11.
• the second through holes 6 are used for passing through fastening means in order to fix the valve 7 to the flat gasket 1 and a further component (not shown).
• FIG. 3 shows a plan view of a further exemplary embodiment of the flat gasket 1 according to the invention.
• the flat gasket 1 shown here is designed to seal a pressure valve (not shown).
• the plate-shaped body 2 of the flat gasket 1 is provided in this exemplary embodiment with three first through-holes 3 for passing through pressure lines of the valve, which are arranged asymmetrically for a the B-shaped body 2 in two equal halves dividing axis B provided. Two of the three first through holes 3 have the same diameter, but the third has the first through holes 3 a larger diameter.
• the asymmetrical arrangement of the first through holes 3 on the plate-shaped base body 2 and their different diameters prevent incorrect assembly.
• each of the three first through-holes 3 is surrounded by an annular collar.
• Another, not shown here sealing measure would be the provision of yet another collar (not shown), which surrounds all of the three first through holes 3 in total, whereby a double seal can be achieved.
• a pair of second through holes 6 are arranged with respect to the axis B on the left half of the plate-shaped main body 2 in Fig. 3.
• the two second through-holes 6 are mirror-symmetrical with respect to the axis A on the plate-shaped base body 2 opposite.
• the openings of the second through-holes 6 are each arranged with a holding device in the form of two in the opening opposite
• a pair of third through-holes 5 are provided, which have a smaller diameter than the second through-holes 6 and, unlike the second through-holes 6, also have no holding devices.
• the two third through-holes 5 are arranged mirror-symmetrically. Overall, results from the arrangement of the through holes with different diameters on the plate-shaped Body 2 an asymmetrical arrangement, which prevents incorrect installation. In addition, a false assembly is further avoided by the fact that the retaining clips 13 are provided exclusively in the through holes with a larger diameter.
• the outer contour 8 of the plate-shaped basic body 2 of the flat gasket 1 substantially corresponds to the outer contour 9 of the valve (indicated by the dashed line in FIG. 3), but at two sections each with a projection 10 is formed opposite the contour 9 of the valve housing. This allows in the installed state, a check whether the gasket 1 is installed.
• Fig. 4 shows a sectional view through a portion of the plate-shaped base body 2 in a region of a second through-hole 6.
• the second through-hole 6 is provided at its opening with a pair of opposing retaining clips 13, which protrude substantially perpendicularly from the plate-shaped base body 2 .
• the retaining clips 13 are integrally formed and made of an elastic material.
• the retaining clips are preferably formed on the base body 2 and thus also coated with an elastomer as well as the main body.
• the flat gasket 1 thus provides an effective seal e.g. a variable displacement before a controller or a valve before. All described and / or drawn features can be combined with each other in the context of the invention.
