Description

В воздушных тормозах известно применение двойного режима работы регул тора хода насоса, осуществл емого соответствующим устройством этого регул тора и крана машиниста.In air brakes, it is known to use a dual mode of operation of the pump stroke regulator, carried out by the corresponding device of this regulator and the driver's crane.

Предлагаемое устройство предназначено дл  получени  двойного режима работы регул тора хода насоса в зависимости от величины давлени  в тормозной магистрали. Это устройство дополнительно устанавливаетс  при обычно примен е.мых кранах машиниста и регул торах хода насоса, которые предусматривают однорежимную работThe proposed device is intended to obtain a dual mode of operation of the pump stroke regulator, depending on the pressure in the brake line. This device is additionally installed with commonly used driver cranes and pump stroke controllers that provide single-mode operation.

На чертеже изображена схема устройства.The drawing shows a diagram of the device.

В корпусе / расположен поршень 2. Камера с правой стороны порш г  2 трубкой 3 сообщаетс  с магистралью 4. Камера с левой стороны поршн  сообщаетс  каналом 5с атмосферой. В этой камере расположена пружина 6, величина давлени  которой на поршепь 2 рассчитана на уравновешивание давлени  воздуха в магистрали 4 несколько ниже зар дной его величины. Внутрьпоршн  2 входит шток 8 клапана 7. Шток 8 проходит через внутреннюю стенку корпуса и уплотнен лабиринтом , Трубкой 9 под клапан 7 подводитс  воздзх из трубки 10 от главного резервуара. Камера над клапаном трубкой // сообщаетс  с воздушной камерой регул тора 12 хода насоса, отрегулированного на величину давлени , соответствующую режиму пониженного давлени , равного 6-6,5 ат.The piston 2 is located in the housing / located on the right side. The chamber on the right side of the piston 2 by tube 3 is connected to the main line 4. The chamber on the left side of the piston is connected by the channel 5 with the atmosphere. A spring 6 is located in this chamber, the pressure of which on the piston 2 is designed to balance the air pressure in line 4 slightly below its charge value. The inner piston 2 enters the stem 8 of the valve 7. The stem 8 passes through the inner wall of the housing and is sealed by a labyrinth. The tube 9 under the valve 7 is supplied from the tube 10 from the main reservoir. The chamber above the valve // is communicated with the air chamber of the pump stroke regulator 12, which is adjusted to a pressure value corresponding to a reduced pressure mode of 6-6.5 at.

При зар дном или отпускном давлении воздуха в магистрали поршень 2 под действием этого давлени  передвигаетс  влево, сжимает пружину 6 и открывает клапан 7. Воздух из главного резервуара поступает через открытый клапан 7 непосредственно в воздушную камеру регул тора 12, вследствие чего регул тор поддерживает в резервуаре величину воздушного давлени  в 6-6,5 ат.When charging or selling air pressure in the line, the piston 2 moves to the left under the action of this pressure, compresses the spring 6 and opens valve 7. Air from the main tank flows through the open valve 7 directly into the air chamber of the regulator 12, as a result of which the regulator maintains in the tank The value of air pressure is 6-6.5 at.

При торможении пружина 6 сдвигает поршень 2 в правое полом еiiiic , показанное на чертеже. Клапан 7 устанавливает в камере над клапаном и в сообщенной с ней воздушной камере регул тора хода насоса да зление, пониженное по сравнению с величиной давлени  в главном резервуаре в отношении, определ емом отношением плош,ади клапана ; площади сечени  штока. В соответствии с этим регул тор переходит на режим, повышенного давлени  в главном резервуаре.During braking, the spring 6 moves the piston 2 to the right-ground eiiiic shown in the drawing. Valve 7 installs in the chamber above the valve and in the air chamber of the pump stroke regulator communicated with it, and the vision is lower than the pressure value in the main tank in the ratio determined by the ratio of the valve to the valve; stock sections. In accordance with this, the regulator switches to the mode of increased pressure in the main tank.
