According to the invention, in the radial direction, the control piston (7) delimits a pressure medium leakage chamber (9) which is sealed from the gas recirculation line (6) by a sealing element (10) and can be connected to a pressure medium recirculation line (12) via a pressure medium cut-off valve (11). The invention further relates to a fuel system comprising a valve assembly (1) according to the invention for controlling the gas pressure in a gas rail (2).
