Definitions

  • the present disclosure relates to an air flow adjustment device for regulating the air flow in an air ventilation arrangement.
  • One solution comprises a turnable plate with a cross-sectional area corresponding to the cross-sectional area of the ventilation tube it is located in. By turning the plate the air flow through the ventilation tube may be regulated.
  • Such solution causes a large amount of noise in the ventilation arrangement. Further, when the air flow is regulated by the plate, the air flow is disturbed and directed by the plate, actions which are not desired.
  • An iris shaped regulator device changes the size of an opening through the iris. Thin plates constitute the iris shape. Such solution still causes a large amount of noise in the ventilation arrangement. Further, an iris shaped regulator is complex to manufacture for ventilation arrangements of large dimensions.
  • the patent application W010039100 discloses an air flow adjustment device comprising a twistable sleeve of flexible material that, when twisted, reduces an air flow opening through the device.
  • the flexible material in the twist sleeve attenuates noise in the device.
  • the disclosed arrangement for twisting the twist sleeve is complex. Such complex arrangement is costly to manufacture and is not reliable over a long period of time.
  • an air flow adjustment device for arrangement in an air ventilation arrangement, wherein the device comprises an outer tube, an inner tube arranged inside the outer tube and rotationally and axially moveable relative to the outer tube, and a twist tube with an axial opening through which air is adapted to flow, wherein the twist tube in a first end is fixed relative to the outer tube and in a second end is attached to the inner tube.
  • the inner tube is adapted to be rotated and axially displaced relative to the outer tube, such that when the inner tube is rotated the twist tube is twisted and the size of the axial opening is changed.
  • the outer tube comprises a helical slot
  • the inner tube is provided with an adjustment handle that extends radially through the helical slot of the outer tube, such that the adjustment handle is adapted to be moved along the helical slot to rotate the inner tube and move the inner tube axially relative to the outer tube.
  • the adjustment handle may be reliable since the handle is directly connected to the inner tube and extends out through the helical slot. There may be no moving parts in between the handle and the inner tube.
  • the handle may be easily accessible for a user to adjust the air flow through the device.
  • the helical slot may guide the handle and thereby also the inner tube in both a rotational movement and an axial movement at the same time.
  • the twist tube may thereby be twisted such that the opening through the twist tube is reduced, which may reduce the air flow.
  • the twist tube When the twist tube is twisted, its axial length may be reduced. This length reduction may be compensated for by the axial movement of the inner tube.
  • the inner tube may have an axial length that is at least as long as the axial extension of the helical slot in the outer tube.
  • the inner tube may have a short axial length, only to provide attachment to the twist tube and the adjustment handle. With a short inner tube less material may be used for manufacturing the air flow adjustment device.
  • the diameter of the inner tube may be slightly smaller than the diameter of the outer tube.
  • the inner tube and the outer tube may be arranged coaxially.
  • the twist tube may be produced of a flexible material.
  • flexible it may be meant that the twist tube is twistable around its own axle.
  • the flexible material may be a material such as fabric, plastic, rubber or the like.
  • Such twist tube may further provide good sound-attenuating properties to the air flow adjustment device. No external sound-attenuating device may thereby be needed.
  • the twist tube may be fixed relative to the outer tube such that the cross-sectional area of the twist tube at that end is substantially equal to the cross-sectional area of the outer tube. At that end of the twist tube, all air adapted to flow through the outer tube may thereby enter into the twist tube. When the twist tube is twisted, the cross-section at a middle portion of the twist tube may be changed.
  • the air flow adjustment device may be adapted to be used for other gases or fluids.
  • the materials in the tubes may thereby be adapted for functioning with a specific gas or fluid.
  • the air flow adjustment device may comprise locking means adapted to, in a locked state, prevent movement of the adjustment handle along the helical slot, and in an unlocked state enable movement of the adjustment handle along the helical slot.
  • the inner tube may be prevented from rotational and axial movement relative to the outer tube when the locking means is in the locked state.
  • a secure positioning of the inner tube may thereby be provided.
  • accidental or unintentional movement may be prevented.
  • the unintended movement may be caused by, for instance, unintended movement of the adjustment handle or vibrations caused by the air flow through the air flow adjustment device.
  • the locking means may be provided on the adjustment handle.
  • a locking means on the adjustment handle may provide an easy access to a locking or unlocking operation.
  • the locking means may be provided as means such that the adjustment handle may be adapted to be lifted in a radial direction to a lifted position, such that the inner tube may be pressed towards the outer tube, and means adapted to hold the adjustment handle in the lifted position.
  • the locking function may be adapted to be operated by a user.
  • the locking means may be provided as threads on a portion of the adjustment handle and a nut adapted to be screwed on the threads, wherein the nut may be adapted to abut an outer surface of the outer tube when screwed on the threads, thereby lifting the inner tube.

  • the locking means may be provided on the adjustment handle as an extending member extending in parallel with an outer surface of the outer tube, wherein the connection point between the adjustment handle and the extending member may be adjustable in the radial extension direction of the adjustment handle.
  • connection point between the adjustment handle and the extending member may be fixed such that the extending member may abut the outer surface of the outer tube and lift the adjustment handle in the radial direction.
  • connection point between the adjustment handle and the extending member may be moved along the radial extension of the adjustment handle.
  • the inner tube and the outer tube may be made of a rigid material, and wherein the twist tube may be made of a flexible, twistable material.
  • the rigid material may be metal such as steel.
  • the flexible, twistable material may be fabric, plastic, rubber or the like.
  • the inner tube and/or the outer tube may be provided with an air sealing arrangement for preventing air flow through the helical slot in the outer tube.
  • the air sealing arrangement may be arranged on the inner tube, the outer tube or on a combination of the two. With an air sealing arrangement, the development of noise in the air flow adjustment device may be prevented. By preventing air flow through the helical slot, disturbance of the air flow through the device may be prevented.

  • the adjustment handle may be provided with a locking function providing a locked and an unlocked state of the adjustment handle. In the locked state the handle may press the inner tube towards an inner surface of the outer tube. The sealing material may thereby seal the helical slot in the locked state. In the locked state the adjustment handle may further prevent rotational and axial movement of the inner tube relative to the outer tube. In the unlocked state rotational and axial movement of the inner tube may be enabled. The inner tube may in the unlocked state of the adjustment handle further be released from the pressing function towards the inner surface of the outer tube.
  • the inner tube may be provided with an axial slit along its entire axial length such that the cross-sectional area of the inner tube is expandable and contractible, wherein the adjustment handle may be attached to the inner tube such that the adjustment handle in a first state may be adapted to contract the cross-sectional area of the inner tube, enabling rotational and axial movement of the inner tube, and in a second state may be adapted to expand the cross-sectional area of the inner tube such that an outer surface of the inner tube presses against an inner surface of the outer tube.
  • the inner tube may thereby expand such that it provides an air seal around the helical slot.
  • the outer surface of the inner tube may be provided with a sealing material. When the cross-sectional area of the inner tube is expanded, the sealing material may thereby provide a sealing between the inner tube and the outer tube.
  • the inner tube may further in the expanded state provide a locking function such that movement of the inner tube relative to the outer tube may be prevented in a locked state.
