Beschreibung
Zusammenfassung:	The present invention regards a valve arrangement comprising a housing and a mainly cylindrical valve element arranged rotatable within the housing, wherein the housing has at least one supply port, at least one exhaust port and at least one outlet/inlet opening. These ports and opening are arranged at a distance from each other along a rotation axis of the valve element. The valve element comprises at least one first bore extending along the rotation axis connecting the supply port with the at least one outlet/inlet opening in one position of the valve element, and at least one second bore extending along the rotation axis connecting the same outlet/inlet opening with the exhaust port in a second position of the valve element, the bores being configured such that they are separated from each other.
