11. A vehicle having at least one fluid valve, having at least one instance of a seal arrangement having:
a first sealing element (10) configured to bear in a sealing manner directly against a valve housing (100) of the fluid valve having a first axially extending portion that extends away from the valve housing;
a second sealing element (20) configured to bear in a sealing manner directly against an adjustable, rotatable, valve body (200) of the fluid valve having a second axially extending portion that extends towards the valve housing; and
an elastically deformable intermediate piece (30) arranged, in an axial direction, entirely between a first wall (12) of the first sealing element (10), the first wall (12) facing the second sealing element (20), and a second wall (21) of the second sealing element (20), the second wall (21) facing the first sealing element (10), so as to elastically space apart the first and second sealing elements (10, 20),
wherein, in at least one axial portion of the intermediate piece (30), an axial cross section of the intermediate piece (30) has a first radial lateral surface (31) and an opposite second radial lateral surface (32), and
wherein the first radial lateral surface (31) is convex and the second radial lateral surface (32) is concave, planar or less convex than the first radial lateral surface (31),
wherein a portion of a radially outer face of the first axially extending portion faces a portion of a radially inner face of the second axially extending portion,
the seal arrangement configured to provide sealing between the valve housing (100) and the adjustable rotatable, valve body (200).
