The invention relates to a spindle assembly (1) for a tire inflation system, the spindle assembly (1) comprising: a spindle (3) defining an axial direction (2) and comprising a fluid conduit (8a, 8b; 8c); a rotatable part rotatably mounted on the spindle (3) and comprising a fluid passage (12a, 12b; 12c), the fluid passage (12a, 12b; 12c) being configured to be in fluid communication with a pneumatic tire; and a dynamic annular seal chamber (31a, 31b; 31c), the annular seal chamber (31a, 31b; 31c) being disposed radially between the spindle (3) and the rotatable part; wherein the fluid conduit (8a, 8b; 8c) and the fluid passage (12a, 12b; 12c) are in fluid communication with each other through the annular seal chamber (31a, 31b; 31c), the annular seal chamber (31a, 31b; 31c) being disposed axially between a first volume and a second volume; and wherein the first volume and the second volume are in fluid communication with each other through at least one fluid channel (43a, 43b, 44a, 44b; 43c, 43d) for leading fluid leaked out of the annular seal chamber (31a, 31b; 31c) and leaked into the first volume and/or into the second volume through the fluid channel (43a, 43b, 44a, 44b; 43c, 43d). |
