Abstract (en)

[origin: WO2017220193A1] A valve apparatus for influencing a flow of medium between a supply port (38) and a pressure port (40), having a valve device (10) which, in at least one closed position, blocks the connection between the supply port (38) and the pressure port (40) and which opens this connection in at least one opened position, in which the pressure port (40) is connected to at least one of two medium chambers (62, 80) by a respective fluid channel (64, 82), of which one (64) consists of a fluid duct (68) in the valve slider (22), is characterized in that the other fluid channel (82) has at least one further fluid duct (84) which is separate from the first fluid duct (68) and which, at least in one of the opened positions of the valve slider (22), opens at one end (92) into the medium chamber (80) and which, in every displacement position of the valve slider (22), is permanently connected at the other end (94) to the pressure port (40).
