The loading-valve arrangement for an accumulator (10) has an accumulator-loading directional control valve (1) which can be actuated by a control device (11) and the piston valve member (15) of which is moved by spring loading into a first control position and which has a first pressure connection (3), which can be connected to a pressure-medium source (10), and a consumer connection (6) or a connection leading to a pressureless tank (7). In order to create an accumulator-loading-valve arrangement which can preferably be used for hydraulic brake servo-units and consists of a control valve of very simple construction, in which case the arrangement can be operated as far as possible in an energy-saving manner, provision is made for the first pressure connection (3) and the consumer connection (6) to be connected in the first control position (rest position) and to be separated in the second control position (working position), and for a second pressure connection (9) to be provided which can be connected to a pressure-medium source (4) and leads into a chamber (16) in the accumulator-loading valve (1; 48), which chamber (16) is partly defined by a piston surface (15a). <IMAGE>
