The invention relates to control devices rotary plates-dampers, related, in particular, to devices for regulating the air flow, ventilation and air-conditioning.

You know the device type blinds for blocking the ventilation duct, comprising a housing, a dial plate synchronously-rotating elements mounted on the shafts with parallel longitudinal axes, site installation at the position of overlap of the ventilation duct and the site of the turning plate elements based on gear, made in the form of identical gears mounted on the shafts of the plate elements on one side of the set and form a gear pair, while the kinematic connection between the gear of one of the gear pairs and the drive is made in the form of additional gear on the opposite side of the respective shaft, and site installation of plate elements in the position overlapping the ventilation channel is made in the form of spring device that is installed in the kinematic chain drive and are triggered when a power outage (see the patent for useful model RU # 30180, publication date 2003.06.20, IPC 7 F24F 13/10, "Device type blinds for blocking the ventilation channel").

The disadvantages of the known devices is the complexity and gr is modcast design, increased consumption of node rotation plate elements based on gear, consisting of a set of gears, exceeding the number of plate elements located on opposite sides of them, which limits the scope of application of the device, not allowing you to use them in a compact ventilation systems in the building solutions limited spatial dimensions.

Regulation of air flow is provided in this case only with the use of a reversible electric drive, which requires placing it in an easily accessible places to control the air flow and maintenance of the device, thus, if necessary, the ability to control the device manually. The increased complexity of service node rotation of plate elements on the basis of the gears increases operating costs.

Also known climatic installation comprising a fan, an evaporator for cooling and a heat exchanger for heating air, is placed in the case in which the outlet openings are butterfly valves with screens, while the flaps are aligned with their supporting parts, which are connected with leads connected by rods with the governing body (see the patent for useful model RU # 2442, publication date 2002.08.10, IPC 7 VN 1/00, F24F 13/14, "Climate control and device control the air flow in it").

In this arrangement, the butterfly valve is installed in grooves made in the supporting parts, while inside the supporting parts are made of the axial screw holes and screwed the screws, the ends of which are placed in grooves made in the flaps. Leashes dampers made of a plate and are located on the screw between its head and the base part, the plates of leads is a spike having a threaded connection with the shaft which has a threaded swivel with screw attached to the body of the control.

The design of the known device lies in the fact that each of the rotary valves is equipped with a leash and requires an individual thrust of a certain length, connected with the governing body, which complicates the device, increases the dimensions and requires individual settings for each butterfly valves.

This air conditioner requires a governing body in the immediate vicinity of the rotary damper device and therefore can be used to control the position of the rotary valves in hard to reach places. There is no possibility to control the rotation of the damper-side fron the real panel of the device in case of difficult access to the exhaust holes with rotary valves.

Stepper motor provides the regulating angle valves with precision values of a given step angle of the motor, i.e. is speed regulation, which is often not enough to ensure accurate adjustment of the flow rate of air.

The task, which directed the claimed technical solution is to simplify the design, creating a compact and reliable device that allows control of synchronous-butterfly dampers when they are placed in hard to control.

The solution of this problem is due to the fact that the control device synchronously-butterfly dampers of the type of blinds that contains the actuator, is provided with an elastic flexible shaft, made in the form of helical springs associated with the actuator and passing through a hole made at a distance of shoulder rotation in one of the synchronously-rotating damper, which is connected with the rest of the flaps by means of a common connecting rod.

The presence of elastic flexible shaft, made in the form of a cylindrical helical spring provides a torque transmission from the drive directly to one of the rotary valves. Due to the fact that all of the synchronously-rotating flap hinged to the common connection of the sustained fashion thrust, becomes possible to transmit torque from the leading flap simultaneously and synchronously other rotary valves.

Execution of the shaft is flexible and elastic makes possible the transmission of torque at a considerable distance from the body control virtually any remote location, rotary dampers, providing easy and precise control of the device through the front grille, with a choice of any center-to-center distances for multiple synchronous rotary valves United by a common thrust.

Controlling airflow through the synchronous rotation of the flaps when the transfer of torque from the actuator through a flexible elastic shaft in any remote place can significantly simplify the design to make it compact and reliable, providing the instrument is used in small spaces and in the limited space of the duct.

The connection of the flexible elastic shaft directly driven and synchronous rotary damper allows adjustment device in an easy to service location from the front surface of the device through the grille ducts that simplifies the process of controlling the flow of air.

Communication flexible elastic shaft with the leading on orotol valve by engagement of the turns of the coil spring, through a hole in the surface of the butterfly valve, allows you to place the actuator on either end of the shaft or at both ends simultaneously.

The presence of the distinguishing features of the claimed technical solution allows to make a conclusion about its compliance with the conditions of patentability of "novelty."

The essential features of the claimed invention, determining the receipt of the indicated technical result that is explicitly not follow from the prior art, which allows to make a conclusion about conformity of the invention to condition patentability of "inventive step".

The condition of patentability "industrial applicability" is confirmed on the example of a specific implementation.

The essence of the inventive device is illustrated technical drawings

which figure 1 presents a view of the device from above;

figure 2 - site of attachment of the ends of the coil springs on the body;

figure 3 presents the leading rotary valve;

figure 4 - view of the device sideways with swivel leashes stalking;

figure 5 - node connections of the swivel damper with a leash;

figure 6 - view of the device at the side of the connecting rod.

The control unit synchronously-butterfly dampers of the type of blinds is provided with an elastic flexible shaft with smoothly curved axis of rotation, made in the form of a screw cylindricus the th spring 1, one end of which is rigidly connected to the actuator 2 - mechanized or manual. In this embodiment, presents a manual actuator in the form of a screw 3 (figure 2)pivotally supported on a bracket 4 attached to the front wall of the housing 5. When you manually drive the screw head 3 is turned by the hand tool (not shown). It is possible to install both ends of the spring 1 two different types of drive - manual and mechanized. For example, on the front wall of the housing 5 - easy to control - you can perform a manual drive as a backup, and on the rear wall of the housing 5 is inaccessible for manual control - install motorized drive, for example, with the use of the electric motor.

In this arrangement, the other end of the spring 1 (figure 1) rigidly attached to the same screw 3 in a remote place to the housing 5 of the device on the bracket 6. Front or rear hinged spring seat is respectively of the bracket 4 or 6, which is hinged screw 3 with wound on his nuts 7, which is separated from the bracket 4 or 6 anti-friction washer 8. A second, identical washer 9 divides the screw head 3 and the bracket 4 or 6. Screw 4 or 6 is mounted inside the end of the spring 1 retainer element 9, which provides a strong connection.

When this wire helical springs 1 goesthrough hole 10 (3), in one of the synchronously-rotating dampers, which acts as the leading flap 11. Hole 10 is placed at a distance from the longitudinal axis of the leading flap 11 that defines a shoulder turn leading valve 11 in its interaction with the helical spring 1, the transmitting torque from the drive 2.

All synchronous-butterfly valves - leading flap 11 and slave valve 12 is provided with supporting parts in the form of axes 13, connected to the leads 14 (figure 4 and figure 5)are pivotally mounted on a common connecting deadlift 15 (6).

Under the influence of the torque of the actuator 2 (in this case - manual) coil spring 1, revolving around its smoothly curved axis, transmits torque leading to the valve 11 due to its rotation in the hole 10, in which the next round of the spring 1, passing through the opening 10, is mated with the surface around the hole 10, acting on the leading flap 11 and turning it to the desired angle, shoulder rotation, which is determined by the distance between the hole 10 and the axle 13 leading the butterfly valve 11.

When turning the leading flap 11 and the torque is transmitted on its leash 14, which rotates in connection deadlift 15, thereby ensuring its plane-parallel movement associated with simultaneous rotation of the slave salonek.

Thus, the claimed technical solution allows you to control rotary valves, regulating the flow of light or air, from the front, easily accessible side of the device through the barrier grid, making the device invisible to others, thus improving its aesthetic quality, which is especially important in compact structures with difficult access for maintenance butterfly dampers.

The solution provides freedom of layout of the control device synchronously-butterfly dampers type blinds, simplifying its design and ensuring placement of valves in hard-to regulate the location, which allows, for example, to embed ventilation in confined spatial conditions in the narrow ducts, where possible access to regulation only by the front protective grid.

The proposed device provides precise adjustment of ventilation systems and air conditioning, a choice of any center-to-center distances for multiple synchronous rotary valves United by a common drive, as well as the simplicity and ease of control, efficiency and improved manufacturability of its manufacture.

The control unit synchronously-butterfly dampers of the type of blinds that contains the drive that is different is eat, it is provided with an elastic flexible shaft, made in the form of helical springs associated with the actuator and passing through a hole made at a distance of shoulder rotation in one of the synchronously-rotating damper, which is connected with the rest of the flaps by means of a common connecting rod.
