Regulating flap but volume control and / or mixing of free media

The innovation concerns a regulating flap but volume control and / or a mixture of gaseous media, in particular air in air conditioners, air conditioners or the like. ^ with a drive source flap wings which can be pivoted jointly into the closed or open positions in each case in the same rotational direction.

There are regulating flaps, which are also referred to as louvre flaps, known for the above purposes, the flap blades when Opening or closing move in the same direction or in opposite directions by the same angle of rotation. The disadvantage of the known designs with concurrently controlled flap blades in that the air flow through the regulating flap is already with a relatively small opening angle, the flap wing already reaches its maximum value, which increases the degree of regulating ability such flaps is very limited.

In the case of the versions with flap blades controlled in opposite directions, a relatively greater ability to regulate is achieved, however these regulating flaps are not so beneficial use to mix different air currents, such as

For example, the versions “it” parallel or in equal stages controlled flap wings, «« on di · flap wings against each other * # γ1ο> »· ** Ί siad- Au ·· * '!« »step ·» b * A the Eos »truk tion · *, with counter-rotating flap wings Abdicntpro \ "l« ut open.

at least two of these are expedient for the mishap ) Regulating flaps mutually assigned in such a way that the flap wings of the two regulating flaps that open first opposite or next to each other, whereby the closure OKWt opening of the flap wings of the two regulating flaps in opposite sense takes place. Due to the turbulence of the clashing different air flow © is on the one hand a good one The renting of the same is achieved and furthermore through the different angular velocities of the flap wings, a very good regulation of the mixing ratio is possible.

Fig. 1 is a schematic cross-sectional view of a regulating flap according to the innovation in the open state and

Fig. 2 shows two regulating flaps of the type shown in Fig. 1 in
an application case. they are called "misoh flaps"
to serve.

The regulating flap IO shown in Fig. 1 has a
Rectangular frame 11 made of an angle profile in which
four flap wings 12, 13, 14 and 15 mounted so that they can be pivoted
are. In their closed positions indicated in dash-dotted lines, the flap wings 12 to 15 fill the entire clear cross-section of the rectangular frame 11:

The wing 12 runs parallel to the regulating flap axis 16 fende position, while the flap wings 13 »14 and 15 oppose- J assume an increasingly inclined position over the axis 16.

The flap wings 12 to 15 are also each with one
Lever arm 17 »18, 19 and 20 connected in a rotationally fixed manner, the free

linden at 21, 22 »23 and 24 on a common operating rod 25 are articulated with a drive source, not shown connected, e.g. a flap servomotor. For this purpose, between the flap servomotor and the actuating rod 25 a rack and pinion gear (not shown) must be provided.

The regulating flaps 10 'and 10 "are used in this case Control of the mixture of air currents, s, B. a cold and warm air flow, the duroh full bsw. dashed arrows are indicated to an intensive mixing of the two air currents in every opening phase of the two regulating flaps to achieve and the mixing ratios in a wide The area to influence is the arrangement of the regulating flaps 10 * and 10 "in such a way that the flaps bsw. 12 ", which practically open the first and close the last of all the flap wings, are directly opposite each other, whereby the closure or opening of the flap wings 12 "to 15" e.g. 12 "to 15" takes place in the opposite sense.
