Seal arrangement for a fluid valve, fluid valve and vehicle

A seal arrangement (2) for a fluid valve (FV), the seal arrangement comprising:

• a first seal (4) that sealing abuts against a pivotably adjustable valve body (VK) of the fluid valve (FV) having, at its radial outer edge, a first axially extending wall;
• a second seal (6) that sealing abuts against a valve housing (VG) of the fluid valve (FV) having, at its radial outer edge, a second axially extending wall, wherein the first axially extending wall and the second axially extending wall extend toward each other at a same radial position and have respective parallel end faces that directly face each other;
• and
• a separate, elastically deformable intermediate piece (8), which is arranged, in an axial direction (X-X) of the seal arrangement (2), between a first wall (12) of the first seal (4) and a second wall (14) of the second seal (6) for elastically spacing apart the first and second seals (4, 6), wherein the second wall (14) is situated opposite the first wall (12),
• wherein, on the first wall (12), there is integrally formed thereon a projection arrangement (13), against which the intermediate piece (8) can be brought into abutment under a load (F), wherein the projection arrangement (13) is arranged radially inside the intermediate piece (8) in relation to a seal opening (10), such that the intermediate piece (8) sealingly encloses the projection arrangement (13), wherein a radial end face of the projection arrangement (13) directly faces a second wall (14) of the second seal (6),
• wherein the intermediate piece (8) has at least one axial section whose cross section has, in relation to the seal opening (10), a first, radially outer lateral surface (16) and an opposite, second, radially inner lateral surface (18), and
• wherein the radially outer lateral surface (16) is at least sectionally concave, and the radially inner lateral surface (18) is at least sectionally convex,
• wherein a cross section of the intermediate piece (8) is a pressure-activated V-shape having a nonconstant cross section along its axial extent, which, under the load (F), realizes both an axial, elastic compression and a bending in an area around a cross-sectional center of the intermediate piece (8).
