Description
Известно устройство дл дросселировани отработанного рабочего тела поршневой машины, преимущественно пневматического привода очистител ветрового стекла автомобил .A device is known for throttling a spent working fluid of a piston machine, preferably a pneumatic drive of a car windscreen cleaner.
Это устройство включает в себ канал дл подвода рабочего тела под поршень машины, канал дл выхода отработанного рабочего тела во всномогательную камеру, сообщающуюс с атмосферой, и приспособление дл дросселировани рабочего тела на входе в камеру. Недостатком такого устройства вл етс больша неравномерность хода щетки, очищающей плоское стекло и невозможность применени пневматического стеклоочистител дл панорамных ветровых стекол, которые устанавливаютс на современных автомобил х.This device includes a channel for supplying the working fluid under the machine piston, a channel for exiting the spent working fluid into the supplementary chamber in communication with the atmosphere, and a device for throttling the working fluid at the entrance to the chamber. The disadvantage of this device is the large unevenness of the stroke of the brush that cleans flat glass and the inability to use a pneumatic wiper for panoramic windshields, which are installed on modern cars.
Предлагаемое устройство устран ет эти недостатки тем, что вспомогательна камера выполнена цилиндрической и снабжена плунжером с конусной частью, перекрывающим полностью или частично выходной канал дл отработанного воздуха. В канале дл подвода сжатого воздуха установлен обратный клапан, перекрываюпиш поступление воздуха под порщень плунжера в конце хода последнего. Дл фиксации требуемого положени плунжера применен регулировочный винт, соосный с плунжерами.The proposed device eliminates these drawbacks by the fact that the auxiliary chamber is cylindrical and provided with a plunger with a tapered part that completely or partially blocks the outlet duct for the exhaust air. A non-return valve is installed in the compressed air supply channel, blocking the flow of air under the plunger at the end of the valve stroke. To fix the required position of the plunger, an adjusting screw coaxial with the plungers was used.
Обеспечение равномерности хода стеклоочистител достигаетс созданием сопротивлени отработанному воздуху в канале выпуска и уменьшением проходного сечени канала. В результате исключаетс значительное изменение скорости выпуска отработанного воздуха и скорости перемещени поршн пневматического двигател .Ensuring the uniformity of the windscreen wiper is achieved by creating resistance to the exhaust air in the exhaust channel and reducing the bore of the channel. As a result, a significant change in exhaust air exhaust velocity and air motor piston movement speed is eliminated.
На чертеже изображена схема устройства.The drawing shows a diagram of the device.
Сжатый воздух от пневмосистемы проходит через штуцер 1 и канал 2 в полость А. Далее воздух попадает через щтуцер 3 к пневмодвнгателю .Compressed air from the pneumatic system passes through fitting 1 and channel 2 into cavity A. Then air passes through valve 3 to the pneumatic joint.
