Abstract
A valve apparatus for influencing a flow of medium between a supply port () and a pressure port () has a valve device (). In one closed position, the valve device blocks the connection between the supply port () and the pressure port (). The valve device opens this connection in one opened position, in which the pressure port () is connected to at least one of two medium chambers () by a respective fluid channel (). One fluid chamber () comprises a fluid duct () in the valve slider (). The other fluid channel () has a further fluid duct () that is separate from the fluid duct (). In one of the opened positions of the valve slider (), the further fluid duct () opens at one end () into the medium chamber (). In every displacement position of the valve slider (), the further fluid duct () is permanently connected at the other end () to the pressure port ().
