(54) РЕГУЛЯТОР РАСХОДА мает нейтральное положение. При откл нении расхода воздуха от заданного значени  сигналы, поступающие от тру ки Вентури 1, в полости кo 4aнднoгo прибора Б и В, вызывают перемещение контакту 7 и происходит соотйетствую щее изменени  положени  исполйитель огомеханизма 2, Статическа  расходна  характеристика командного прибора 3, как и датчика расхода трубки Вентури, гипе болйческа  крива , что обеспечивает минимсшьнре отклонение величины регу лируемого расхода от заданной. Положительный эффект от изобретени  заключаетс , например, в повышении комфортности кабин пассажирских самолетов, так как стабилизированный расход в линии поддува устран ет колебани  давлени  в кабине пассажирского самолета. Формула изобретени  Регул тор , содержащий тру бопровод, в котором установлен датчи расхода, выполненный в Аиде i трубки Вентури, исполнительный механизм и св занный с ним командный прибор,о тличающнйс  тем, что, с целью повышени  точности, командный прибор выполнен в виде корпуса, разделенного двум  мембранами с жесткими центрами на три полости, причем одна крайн   полость соединена с узким сечением трубки Вентури и содержит пружину, опиргиощуюс  на жесткий центр мембраны, а друга  крайн   полость соединена с трубопроводом перед трубкой Вентури и содержит электроконтак ную группу, один контакт которой закреплен на жестком центре мембраны. Источники информации, прин тые во внимание при экспертизе: 1.Авторское свидетельство СССР 325445, кл. & 05 Д 16/06, 1967. (54) FLOW REGULATOR wears neutral position. When the air flow rate is not set to a predetermined value, the signals from the Venturi tube 1 in the cavity of the 4 nd device B and C cause the movement of the contact 7 and the ohmechanism 2 operator changes position, the static flow characteristic of the command device 3, as well as the sensor flow rate of the venturi, hype-free curve, which ensures the minimum deviation of the value of the adjustable flow from the specified one. The positive effect of the invention is, for example, in increasing the comfort of the cabin of passenger aircraft, since the stabilized flow rate in the blowing line eliminates pressure fluctuations in the cabin of the passenger aircraft. Claims of the Invention A regulator comprising a pipeline in which a flow sensor installed in Aida i of the Venturi tube, an actuator and associated control device is installed, which is characterized by the fact that the control device is designed as a housing, divided by two membranes with rigid centers into three cavities, with one extreme cavity connected to the narrow section of the Venturi tube and containing a spring that is attached to the rigid center of the membrane, and the other extreme cavity connected to the pipeline in front of the pipe Venturi and contains hydrochloric elektrokontak group, one contact of which is fixed on the hard center of the membrane.
