  • the position of the valve 10, 100 may be changed towards the closed position or towards the open position depending on the direction of rotation.
  • Turning of the bowl-shaped element 113 causes the outer rotor element 111 to turn in the same direction of rotation, and therewith the protrusions 125 of the inner rotor element 121 present in the slots of the outer rotor element 112.
  • the protrusions 125 extending through the slots of the outer rotor element 112 and received in the at least one inner slot 135 of the stator element 131, are guided by the at least one inner slot 135 when turning the bowl-shaped element 113. Due to the fact that the at least one inner slot 135 extends in the axial direction A, the axial position of the guided protrusions 125 change relative the stator 130 and the outer rotor part 110. Because of that the axial position of the ring-shaped element 126 of the inner rotor part 110 is changed relative to the bowl-shaped element 113.
  • the flow or pressure of air flowing through the valve 10, 100 is adjusted because the air passage through the valve is defined by the space between the bowl-shaped element 113 and the ring-shaped element 126.
  • the flow rate is increased by turning the bowl-shaped element 113 clockwise and the flow rate is decreased by turning the bowl-shaped element 113 clockwise, or vice versa.
  • Other alternatives and equivalent embodiments of the present invention are conceivable within the idea of the invention, as will be clear to the person skilled in the art. The scope of the invention is limited only by the appended claims.
