Abstract: Использование: система регулирования энергетической установки, в частности дизеля с турбонаддувом. Сущность изобретения: система регулирования снабжена исполнительным механизмом, который содержит запорный орган 3 и пневматический чувствительный элемент 5, разделенный на рабочую 44 и атмосферную 45 полости эластичной подпружиненной мембраной 7, сквозь жесткий центр 8 которой проходит винт 9 регулирования мощности, имеющий резьбовое соединение со штоком 28. Рабочая полость 44 через дросселирующее отверстие 6 связана с впускным трубопроводом двигателя (или другим источником избыточного давления), а через запорный орган 3 может сообщаться с атмосферой. Как только один из контролируемых параметров двигателя, например температура отработавших газов, превысит допустимую величину, сигнал с термопары поступает на электронный блок 2, который подает напряжение на нагревательный элемент 21. Тепло передается термочувствительному элементу 20, который, удлиняясь влево, торцом хвостовика 19 перемещает шарик 17. Последний отходит влево, отпирает стравливающее отверстие 49 и часть воздуха из полости 44 через первую полость 47 попадает во вторую замкнутую кольцевую полость 48, а затем через радиальные каналы, кольцевой зазор 25, резьбу 26 и паз 27 стравливается в атмосферу. В результате этого мембрана 7 с винтом регулирования мощности и штоком 28 перемещается вверх и через систему рычагов ограничивает подачу топлива. Возможен вариант, когда вторая полость 48 может быть выполнена в термочувствительном элементе 20 и связана с первой полостью через отверстие 49 с отверстием, выполненным в хвостовике 19 термочувствительного элемента. Полость 48 связана с атмосферой через радиальные каналы, кольцевой зазор 25, резьбу 26 и паз 27. 4 з.п.ф-лы, 7 ил.
