Кроме того, окна 6 стакана 5 и окна 9 диска 8 имеют форму диаметрально расположенных секторов. Диск 8 прижимается к дну стакана 5 с помощью пружины 11_f которая опирается на шайбы 12 и 13. Толкатели 3 и 4 установлены на подвижном воздуховоде 1 с помощью стержней 14 и 15, зазоры между неподThe device comprises movable and stationary air ducts 1 and 2, respectively, while the duct I is equipped with pushers 3 and 4, the duct 2 has a shutter made in the form of a cup 5 with windows 6 and a rotary shaft 7 mounted along the axis of the cup, provided with a rotary shaft from the bottom of the cup 5 a disk 8 with windows 9, and with the opposite finger 10, interacting with the pushers 3 and 4. In addition, the windows 6 of the glass 5 and the windows 9 of the disk 8 are in the form of diametrically located sectors. The disk 8 is pressed to the bottom of the cup 5 with a spring 11 _f which rests on the washers 12 and 13. Pushers 3 and 4 are mounted on the movable duct 1 using rods 14 and 15, the gaps between the

Устройство работает следующим образом . ₅ The device operates as follows. ₅

При движении воздуховода 1 вдоль воздуховода 2. толкатель 3 взаимодействует с пальцем 10, поворачивая его. Вместе с ним поворачивается и вал 7 с диском 8. При повороте диска ю 8 его. окна 9 совмещаются с окнами 6 стакана 5 и воздух поступает из воздуховода 2 в воздуховод 1. При дальнейшем движении воздуховода 1 во взаимодействие с пальцем 1 вступает 15 толкатель 4, поворачивая тем самым диск 8, при этом происходит перекрытие отверстий 6 стакана 5 и подача приточного воздуха прекращается. В это же время, толкатель 3 начинает открывать 20 следующий затвор, обеспечивая непрерывную подачу приточного воздуха в воздуховод 1.When the duct 1 moves along the duct 2. The pusher 3 interacts with the finger 10, turning it. Together with it, the shaft 7 with the disk 8 rotates. When the disk is rotated, its 8th. the windows 9 are combined with the windows 6 of the cup 5 and the air enters from the duct 2 into the duct 1. With the further movement of the duct 1, the pusher 4 interacts with the finger 1, thereby turning the disc 8, thereby closing the holes 6 of the cup 5 and supply air stops. At the same time, the pusher 3 begins to open 20 the next shutter, providing a continuous supply of fresh air into the duct 1.

Применение данного изобретения позволяет сократить утечку приточ- 25 ного воздуха за счет повышения герметичности, что приводит к эконо мии электроэнергии, идущей на обработку и подачу приточного воздуха.The use of this invention allows to reduce the leakage of the supply air by increasing the tightness, which leads to the saving of electric energy used for processing and supplying the supply air.

Claims

The invention relates to ventilation and air conditioning and serves to supply ventilation air to the cabs of the moving mechanisms. Ventilating devices are known that contain movable and fixed ducts, the first of which is provided with pushers and the second with a shutter D J. The lack of these devices is a low leaktightness, as a result of which a large loss of supply air occurs. The purpose of the invention is to increase the ticiness. The goal is achieved by the fact that the shutter is made in the form of a glass with windows and installed on the axis of the stack on a rotary shaft, equipped with a window with windows from the bottom of the last, and with an opposite finger that interacts with the pushers shape diametrically located sectors. FIG. 1 shows the device, a general view; in fig. 2 shows a section A-A in FIG. in fig. 3 - shutter, top view. The device contains movable and stationary air ducts 1 and 2, respectively, while air duct I is equipped with pushers 3 and 4, air duct 2 - with a shutter made in the form of a cup 5 with windows 6 and a rotatable shaft 7 installed along the axis of the cup and equipped with the bottom 5 of the cup a rotary disk 8 with windows 9, and on the opposite side with a finger 10 interacting with pushers 3 and 4. In addition, windows 6 of cup 5 and windows 9 of disk 8 have the form of diametrically located sectors. The disk 8 is pressed against the bottom of the cup 5 with a spring 11f which rests on washers 12 n 13. The pushers 3 and 4 are mounted on a movable duct 1 by means of rods 14 and 15, the gaps between the non-motion duct 2 and the movable 1 are sealed by elastic tapes 16 and 17. The device works as follows. When the duct 1 is moving along the duct 2, the pusher 3 interacts with the finger JO, turning it. The shaft 7 with the disk 8 also rotates with it. When the disk 8 rotates it. Windows 9 are aligned with the windows 6 of the cup 5 and the air enters from the duct 2 into the duct I. Upon further movement of the duct I, the pusher 4 enters into interaction with a finger, thereby turning the disk 8, thus blocking the openings 6 of the cup 5 and supplying full air is terminated. At this time, the pusher 3 begins to open the next shutter, providing a continuous supply of supply air to the duct 1. The use of this invention reduces the leakage of supply air by increasing air tightness, which leads to the economy of electricity required for processing and supplying supply air. Claim 1. Ventilating device containing under and fixed air ducts, the first of which is equipped with pushers, and the second shutter, characterized in that, in order to improve the tightness, the shutter is made in the form of a glass with windows and installed along the axis of the glass of the rotary shaft, equipped with a rotating disk with windows at the bottom of the last, and with a finger interacting with pushers at the opposite.

2. A device according to claim 1, characterized in that the windows of the bottom of the glass and the disk have the shape of diametrically located sectors. Sources of information taken into account in the examination 1. ABTOpCkoe USSR certificate № 362177, cl. F. 24 F 7/04, 1970.
