"textContent": "The invention relates to a hydrostatic drive system (1) of a mobile work machine, in particular a materials handling vehicle, with an internal combustion engine (2) and a work hydraulic system (4) driven by the internal combustion engine (2), wherein the work hydraulic system (4) comprises at least one hydraulic pump (7) driven by the internal combustion engine (2), wherein the hydraulic pump (7) draws pressure medium from a reservoir (9) on its suction side and conveys it into a delivery line (10) guided to the work hydraulic system (4), and wherein the drive system comprises a supply circuit (20) and is provided with at least one pressure medium accumulator (25). According to the invention, the pressure medium accumulator (25) is provided for supplying the supply circuit (20) with pressure medium, wherein the pressure medium accumulator (25) is connected to the delivery line (10) of the hydraulic pump (7) by means of a charging line (26) for loading with pressure medium and a supply pressure supply line (21) is connected to the pressure medium accumulator (25) for supplying the supply circuit (20), wherein a pressure control valve (40), in particular a pressure reducing valve (41), is arranged in the supply pressure supply line (21) and an isolation valve (50) operable between a blocking position (50a) and a flow position (50b) is arranged in the charging line (26).",
