Abstract

A control device has a flow divider valve (3) which is connected to a high-pressure pump (2) and from which a so-called pilot flow line (4) is led to a control valve (6) of a first adjustment device (7) which constitutes a control device. The pressure regulation during the adjustment of the control valve (6) takes place by means of the pilot flow line (4). A flow branch (5) leads from the flow divider valve (3) to an actuation valve (10) of a second adjustment device (11). The flow divider valve (3) has a plate orifice (19) which, in the direction of flow, is located downstream of a metering edge (18). A further flow branch (21) for the working flow of the control device (adjustment device 7) is connected between the metering edge (18) and the plate orifice (19). By means of this tapping off of the working flow for the control device, the usually higher working pressures of the second adjustment device (11) cannot act on the control valve (6). <IMAGE>
