- FIG. 1 shows a manually operated variant of the flow control device according to the invention, which is illustrated in the upper part of the figure in the closed state and in the lower part of the figure in the open state.
- the flow control device has a housing 1, movable locking elements 4 arranged transversely to the flow path of the medium and in the closed position covering the inner cross section of the housing 1, and an actuating device 11 connected to the movable locking elements 4.
- the flow regulator device is further provided with fixed blocking elements 5 cooperating with the movable blocking elements 4, which form a fixed grid 15 having concentric rings, which is reinforced with webs in the direction of the diameter.
- the movable locking elements 4 are designed as concentric rings and together form an axially displaced Slidable webs 13 arranged in the direction of the diameter, reinforced movable grille 14. In a pressed position, the annular blocking elements 4, 5 of the fixed grille 15 and of the movable grille 14 lie against one another, blocking off the flow path of the medium, as can be seen from the upper half of FIG. 1 can be seen.
- the movable grating 14 is connected to an actuating device 11 acting in the axis direction.
- the actuating device 11 is provided with a pulling device 1B and a chain 16 which is connected to an axle 19 which is biased in the locking direction by means of a spring 6.
- a hub 2 On the axis 19 is connected via its screw thread 20 a hub 2 carrying the movable grating 14.
- the movable grille 14 is guided in the housing 1 so as to be displaceable in the axial direction and is secured against rotation by means of a guide lug 12 fastened to the housing 1.
- the end of the axle 19 which is farther from the hub 2 is also guided in a housing 17 which accommodates the spring 6 and is displaceable in the axial direction, the housing 17 being supported on the casing of the housing 1 by means of retaining ribs 10.
- FIG. 1 The embodiment of the flow control device according to the invention illustrated in FIG. 1 functions as follows:
- the movable grille 14 In the closed position shown in the upper part of the figure, the movable grille 14 is pressed against the fixed grille 15 by the hub 2 and via the axis 19 by the spring 6, while the movable and fixed locking elements 4, 5 adjacent to each other, block the path of the air flow. With the aid of the pulling device 18 and via the chain 16, the axis 19 can be displaced against the spring 6 in the axial direction into the position corresponding to the lower half of the figure.
- the movable locking elements 4 of the movable grille 14 move away from the fixed locking elements 5 of the fixed grille 15, which clears the way for the air flow through the openings between the locking elements 4, 5. It can be seen that a small axial movement releases a relatively large flow cross section.
- a pull magnet can also be installed in the housing 17 instead of the manual solution.
- FIG. 2 shows a variant of the flow control device according to the invention actuated by means of a motor, which is shown in the upper half of the figure in the closed state and in the lower half of the figure in the open state.
- the difference from the embodiment shown in FIG. 1 is that the axis 19 is connected to an electric rotary machine 7, or at the same time the axis thereof.
- the screw thread 20 and the rotary machine 7 together form the actuating device 11.
- the embodiment of the flow control device according to the invention which is designed according to FIG. 2, functions as follows:
- the rotary machine 7 rotates the axis 19 which, depending on the direction of rotation via the screw thread 20, the hub 2 and the movable grating 14 attached to it
- Axis direction moves because the latter can not turn.
- an extremely large axially directed force can be exerted, which enables secure locking.
- Figure 3 shows one of those with one in the axial direction Slidable rotor 9 provided with electrical rotary actuated embodiment of the flow control device according to the invention, which is combined with an axial fan.
- the rotary machine 7 In the upper part of the figure the rotary machine 7 is shown in the idle state and in the lower part of the figure in the operating state.
- the special feature of this combination is that the movable grille 14 is assembled with the paddle wheel 3, the locking elements 4 in the movable grille 14 being held in a concentric position by the blades of the paddle wheel 3.
- the paddle wheel 3 and the movable grating 14 are assigned to a common hub 2, which is attached to the axis of the electrical rotary machine 7.
- the actuating device 11 has the following structure:
- the rotor 9 of the rotary machine 7 can be displaced in the axial direction and the spring 6 arranged in the rest position between the rotary machine 7 and the hub 2 pulls the rotor 9 up to 10-40% of its length out of the stator 8.
- the spring force of the spring 6 holds the movable grille 14 and the fixed grille 15 in a closed position.
- the embodiment of the flow control device according to the invention illustrated in FIG. 3 functions as follows:
- the rotary machine 7 When switched on, the rotary machine 7 functions as a pull magnet which moves the movable grating 14 fastened to the hub 2 against the spring 6 in the opening direction.
- the locking elements 4, 5 move away from each other and the rotary machine begins to rotate and also rotates the paddle wheel 3 and the movable grating 14 attached to it.
- the rotor 9 of the rotary machine 7 can never be the magnetically optimal one Take up position, because the spring 6 directs him out of this - albeit to a small extent. For this reason, the efficiency of the rotary machine 7 is reduced to a certain extent. This can be at least partially compensated for by the aerodynamic force acting on the paddle wheel 3 if the direction of the air flow corresponds to that of the hollow arrow in the figure.
- FIG. 4 shows a variant of the flow regulator device according to the invention opening with a helical bolt and a pair of bolt grooves in combination with a radial ventilator in the closed state
- FIG. 6 illustrates the same flow regulator device in the open state.
- This embodiment differs from the previous one on the one hand in the design of the paddle wheel 3, which is well known to the person skilled in the art, and on the other hand in the solution of the actuating device 11.
- the paddle wheel 3, or more precisely the movable grille 14 attached to the paddle wheel 3, is forced into the closed position by the spring 6.
- Figure 5 shows a possible variant of the adaptation of the Locking elements 4.5 on an enlarged scale.
- the pressure difference which acts on the flow regulator device in the closed state acts to a greater extent on the blocking element 4 or 5, the effective surface of which is larger in the plane perpendicular to the axis direction, ie its inclination or taper is greater. It is advisable to take this into account when opening and closing and when determining the direction of the air flow.
- FIG. 7 shows a similar embodiment of the flow regulator device according to the invention illustrated in FIG. 4, which is combined with an electric rotary machine with a rotor which can be displaced in the axis.
- the flow control device In the upper part of the figure is the rotary machine 7, the flow control device is closed, while in the lower part of the figure the rotary machine 7 is running and the flow control device is in the open state.
- the function essentially corresponds to the function of the embodiment illustrated in FIG. 3.
