Abstract
The invention relates to a directional poppet valve (10), comprising valve pistons (16-22) arranged in a valve housing (12) for controlling a plurality of fluid connections (A, B, P, T), wherein the positions of each of the valve pistons (16-22) in the valve housing (12) can be changed by means of at least one actuating device, and wherein the fluid connections (A, B, P, T) are connected to one another or separated from one another alternately depending on the position of the valve pistons (16-22). The invention is characterised in that the valve pistons (16-22) are arranged inline along at least one axis (R), consecutively and/or at least such as to partially interengage, in the valve housing (12).
