Description

Изобретение предназначаетс  преимущественно дл  длинных железнодорожных составов, в цел х ускорени  действи  отдаленных от паровоза тормозных приборов .The invention is intended primarily for long trains, in order to accelerate the effect of brake devices distant from the engine.

На чертеже изображен осевой продольный разрез ускорител , навинчиваемого на снабженный краном /5 штуцер 77 главного воздухопровода 76. Ускоритель состоит из коробки 19, заключающей в себе полый трехкамерный поршень 20, в котором средн   камера 27 находитс  в посто нном С1эобщении с главным воздухопроводом . Камера 28 имеет обращенное в сторону камеры 27 отверстие, закрываемое клапаном 22, соединенным супругой диафрагмой 21 и нагруженным пружиной 24. Противоположна  стенка камеры 28 имеет калиброванное отверстие 26, которому соответствует сквозной канал в теле нагруженного пружиной 25 клапана 23, перекрывающего вы содное отрер1стие из цилиндра 19.The drawing shows an axial longitudinal section of an accelerator screwed onto a crane / 5 fitting 77 of the main air duct 76. The accelerator consists of a box 19 containing a hollow three-chamber piston 20 in which the middle chamber 27 is in constant C1 communication with the main air duct. The chamber 28 has an opening facing the chamber 27, closed by a valve 22 connected by the spouse diaphragm 21 and loaded with a spring 24. The opposite wall of the chamber 28 has a calibrated orifice 26, which corresponds to a through channel in the body of a valve 23 loaded with a spring 25, blocking the cylinder from nineteen.

При зар женном тормозе давление по обе стороны поршн  20 равно давлению главного воздухопровода, и клапаны 22 и 23 прижаты к своим сздлам.With a charged brake, the pressure on either side of the piston 20 is equal to the pressure of the main air duct, and valves 22 and 23 are pressed to their seats.

При служебном торможении с понижением давлени  в главном воздухопроводе диафрагг-, 21 подаетс  влево, открыва During service braking with a decrease in pressure in the main air duct diaphragg, 21 is fed to the left, opening

проход воздуху под клапан 22 в камеру 28 н далее через отверстие 26 и канал клапана 23 в атмосферу, отчего происходит местное понижение давлени  и более энергична  передача волны соседним вагонам . Поршень же 20 под вли нием пружины остаетс  на Месте.the passage of air under the valve 22 into the chamber 28 n further through the opening 26 and the channel of the valve 23 to the atmosphere, which causes a local decrease in pressure and more energetic wave transmission to the neighboring cars. The piston 20, however, remains under the influence of the spring in place.

При резком понижении давлени  в главном воздухопроводе (экстренном торможении ), весь поршень 20 перемещаетс  влево, отжима  клапан 21, открывающий свободный проход воздуху в атмосферу через отверстие в стенке цилиндра 19, закрываемое тотчас же стенкой камеры 28 поршн  20.With a sharp decrease in pressure in the main air duct (emergency braking), the entire piston 20 moves to the left by pressing the valve 21, which opens the free passage of air into the atmosphere through an opening in the wall of the cylinder 19, which is immediately closed by the wall of the chamber 28 of the piston 20.

Предмет изобретени .The subject matter of the invention.

Ускоритель торможени  в воздушных тормозах, отличающейс  применением коробки 19, навинчиваемой на штуцер 77 главного воздухопровода и включак щей в себе полый трехкамерный поршень 20, в котором камера 27, отделенна  от камеры упругой диафрагмой 21, посто нно сообщаетс  с главным воздухопроводом , камера же 28 с калиброванным отверстием, проход щим через тело клапана 23, разобщена от камеры 27 при зар женном тормозе клапаном 22, нагруженным спиральной пружиной 24 и св занным с отмеченной диафрагмой 2/. ка-. ковой поршень 20 при служебном тормо жении, остава сь под вли нием пружинь 25 на месте, открытием клапана 22 дает проход воздуху из главного воздухопровода в атмосферу, ограниченный калиброванным отверстием 26 и станов щийс  свободным по открытии клапана 23 при передвижении поршн  20 при резком понижении давлени  в главном воздухопроводе в момент экстренного торможени .A braking accelerator in air brakes, characterized by the use of a box 19, screwed onto the choke 77 of the main air duct and including a hollow three-chamber piston 20 in which the chamber 27, separated from the chamber by an elastic diaphragm 21, constantly communicates with the main duct, while the calibrated orifice passing through the valve body 23 is separated from the chamber 27 with the brake 22 loaded with the coil spring 24 and connected to the marked diaphragm 2 /. ka- During service braking, the piston 20, remaining under the influence of the springs 25 in place, opens valve 22 to allow air to pass from the main air duct to the atmosphere limited by the calibrated orifice 26 and become free by opening the valve 23 when the piston 20 moves with a sharp decrease in pressure in the main air duct at the time of emergency braking.
