Abstract
A rotary valve comprises a stator member with a stator face, the stator member having at least two stator channels for conducting a fluid and opening into the stator face; a rotor member with a rotor face facing and in contact with the stator face, the rotor member having a rotor channel in the rotor face, wherein the rotor member is rotatable with respect to the stator member about a rotation axis, such that in a conducting position, the rotor channel interconnects the at least two stator channels to be in fluid communication; and a rotary encoder assembly adapted for determining a rotary position of the rotor member, the rotary encoder assembly comprising an encoder member and an encoder module, which is adapted to sense a rotary position of the encoder member. The encoder member is rigidly connected to the rotor member and surrounds the rotor member.
