NON-STICKING ROTARY VALVE

A rotary valve comprises a stator member with a planar stator face, the stator member having a plurality of stator channels for conducting a fluid and a rotor member with a planar rotor face facing and in contact with the stator face, the rotor member having at least one rotor channel. The rotor mem...

Beschreibung
Zusammenfassung:	A rotary valve comprises a stator member with a planar stator face, the stator member having a plurality of stator channels for conducting a fluid and a rotor member with a planar rotor face facing and in contact with the stator face, the rotor member having at least one rotor channel. The rotor member is rotatable with respect to the stator member, such that in specific rotor positions, the rotor channel interconnects two of the stator channels, such that the stator channels are in fluid communication. One of the stator member and the rotor member is made of ceramics material, wherein the other one of the stator member and the rotor member is made of a polymer material. The ceramics material is coated with a diamond-like carbon (DLC).
