The present invention relates to a charging device (1), in particular an exhaust-gas turbo charger for a motor vehicle, comprising a shaft (3) which is supported in a housing (2), and which carries a turbine wheel (6) on the turbine side, and a compressor wheel (8) on the compressor side, wherein the shaft (3) is supported by means of at least one bearing device (9) in the housing (2), wherein a lubricant supply channel (10) is provided through which the bearing device (9) is supplied with lubricant, wherein in the lubricant supply channel (10), a filter device (11) with at least one filter element (12) is arranged. For this, it is essential for the invention that the filter element (12) is pretensioned by means of a spring device (13) against a seal seat (14), wherein the spring device (13) and the filter element (12) is formed in a manner that at exceeding of a predefined lubricant threshold pressure, the filter element (12) disengages from the seal seat (14), and releases a bypass (15) which bypasses the filter element (12).
