Abstract

Исполнительный механизм (50) содержит ползун (52), несущий по меньшей мере два выступа (54, 56) и предназначенный для скольжения в цилиндре, и две камеры (62, 64) управления, соединенные с соответствующими рабочими отверстиями (U1, U2) управляемого электрически гидравлического распределителя (20) сервоклапана. Камеры (62, 64) управления расположены каждая на одной стороне соответствующего выступа, а промежуточная камера, соединенная с высоким или низким давлением, расположена между другими сторонами выступов. В случае отказа электрического управления ползун распределителя (20) переводится в защитное положение, в котором в камерах (62, 64) управления исполнительного механизма устанавливается одинаковое низкое или высокое давление, противоположное давлению, создаваемому в промежуточной камере (66), так, что на каждый выступ (54, 56) ползуна исполнительного механизма действует высокое давление на одной стороне и низкое давление на другой стороне. Герметизация между каждым выступом (54, 56) ползуна исполнительного механизма и цилиндром (60) исполнительного механизма обеспечивается динамическим уплотнением (70), которое создает силу трения между выступом и цилиндром в зависимости от разности давлений, которые действуют на две стороны выступа, так, что в случае отказа электрического управления ползунковый клапан исполнительного механизма останавливается в своем положении на момент отказа ("замораживание отказа"). Исполнительный механизм (50) может быть блоком измерения топлива авиационного двигателя.
