Zusammenfassung:	The invention relates to a valve for alternately filling two working chambers (A, B) of a piston-cylinder system (1, 2, 3) of a pump with a fluid, wherein the valve has two valve pump outlets (PA, PB), for connection to the working chambers (A, B) of the pump and has a valve control element (64) that is displaceably arranged in a space of a valve housing (60, 61, 76, 77) and can be movably driven backwards and forwards between two end positions by a fluid, wherein the valve control element (64) has control ducts (67, 82, 83, 84) that co-operate with housing ducts (51, 71, 72, 80, 81) arranged in the valve housing (60) wherein the first valve pump outlet (PA) is connected to the housing ducts (71, 80) and the second valve pump outlet (PB) is connected to the housing ducts (72, 81), wherein in a central region between the two end positions the valve pump outlets (PA, PB) are connected to one another via control ducts (82, 83, 84) of the valve control element (64).
