Abstract
Гидравлический привод (1a, 1b), в частности, амортизационного и/или демпфирующего типа, содержащий поршень (2), который размещен так, что он может герметично скользить в полом цилиндре (3), для того чтобы разделять внутренний объем полого цилиндра (3) на две камеры (4, 5), отделенные друг от друга головкой (6) поршня (2). Две камеры (4, 5) выполнены с возможностью отдельного соединения соответственно посредством по меньшей мере одного канала (17) подачи и по меньшей мере одного канала (18) отвода с первым контуром, выполненным с возможностью подачи под давлением первой текучей среды в один из них с последующим опустошением другого для выдвижного и сжимающего движения сжатия поршня (2) относительно полого цилиндра (3). Гидравлический привод содержит первый выполненный с возможностью перемещения элемент (7), который размещен так, что он может герметично скользить в продольной полости (8), образованной внутри штока (9) поршня (2), для того чтобы разделять продольную полость (8) на два участка (10, 11), причем первый участок соединен с одной из двух камер (4, 5) и второй участок выполнен с возможностью соединения со вторым контуром, выполненным с возможностью подачи под давлением второй текучей среды во второй участок (11). Вторая текучая среда имеет коэффициент сжатия и номинальное давление, которые выше, чем у первой текучей среды, для того чтобы действовать в качестве амортизатора и/или демпфера в случае резкого скачка давления в камере (4, 5), соединенной с первым участком (10) продольной полости (8), образованной внутри штока (9) поршня (2).
