Abstract

Изобретение относится к области электрогидравлических систем и, в частности, к сервоклапанам регулировки расхода, которые используют преимущественно в системе впрыскивания топлива в летательных аппаратах. Сервоклапан с памятью положения смодержит электрический двигатель и распределитель с управляемым этим двигателем гидравлическим золотником, центральную качалку, оборудованную поршневыми поясками, предназначенными для взаимодействия с соединительными отверстиями распределителя и образующими между собой и с концами распределителя кольцевые полости, из которых две рабочих полости связаны с ведомым органом, которым нужно управлять. В качалке проточены два рабочих канала для установки соединения каждой из названных рабочих полостей с размещенной непосредственно рядом с ней кольцевой полостью таким образом, чтобы обеспечивать одинаковое давление с двух сторон от поршневых поясков, которые разделяют эти две полости. В положении защиты (которое называют положением аварийного стопорения) названные поршневые пояски перекрывают названные рабочие отверстия с зазором, в результате чего потоки из рабочих отверстий направляются через эти зазоры на сливание с определенным низким давлением, что обеспечивает контроль медленного смещения управляемого органа.
