- openings 138a, 138b of respectively a locking mechanism and a ratchet mechanism, extending axially from the lower end of the stator element 131 to allow insertion of a complementary element by a user when installed and extending radially the inner surface 132 to allow interaction between the complementary element and the outer surface of the outer rotor element 111.
- the ratchet means 150 interact with the corrugated surface 117 of the outer rotor part 110 to limit the rotational movement between the stator 130 and the rotor parts 110, 120 to clockwise or counterclockwise movement in the angular direction.
- the stator element 131 further comprises a plurality of countersunk or counterbored holes 139 on its outer surface to receive a respective screw or the like 170 that extends in a respective recessed surface 116 of the outer rotor element 111 to mechanically retain the outer rotor part 110, and thereby also the inner rotor part 120, inside the annular stator element 131, i.e. in the space defined by the annular stator element 131 and the lower ring 136.
- the screw 170 and recesses 116 further limit the rotational movement of the outer rotor part 110 in the angular direction.
- the valve 10, 100 comprises adjustment means and flow regulating means for regulating the flow or pressure of air flowing through the valve 10, 100.
- the adjustment means comprises the bowl-shaped element 113, optionally attached to the proximal end 21, that are rigidly connected to the outer rotor element 111.
- 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.
