An arrangement for the controllable dosing of a fluid working medium which is under a pressure difference to at least one consumer with a control opening is described, which is variable in passage cross-section by displacing a control piston (11), which has a control edge and is held axially displaceably in a cylinder (12), in relation to an outlet slot (13) arranged in the wall of the cylinder. In order to provide a more simple outlet slot (13), in other words one which can be manufactured with greater width dimensions, the control opening is to be assigned an arrangement (15) which reduces the effective passage cross-section and consists of a material with a defined porosity. <IMAGE>
