Claims (1)

Описан предварительно управляемый сервоклапан с по меньшей мере тремя подключениями к основному потоку, для экономящего размеры встраивания в управляющий блок. Устье в управляющей гильзе для первого подключения к основному потоку расположено напротив лобовой плоскости главного управляющего поршня. В камере выравнивания давления главный управляющий поршень образует площадку выравнивания давления. Камера выравнивания давления гидравлически соединена через канал уменьшения давления в главном управляющем поршне, с первым подсоединением к основному потоку. Пружина обратной установки передает на главный управляющий поршень пружинящее усилие в направлении первой аксиальной конечной установки и определяет тем самым однозначно безопасную конечную установку. Клапан отличается хорошими динамическими свойствами.A pre-controlled servovalve is described with at least three connections to the main flow, for saving in size into the control block. The mouth in the control sleeve for the first connection to the main flow is located opposite the frontal plane of the main control piston. In the pressure balance chamber, the main control piston forms a pressure equalization pad. The pressure equalization chamber is hydraulically connected via a pressure reduction channel in the main control piston, with a first connection to the main flow. Spring return installation transmits to the main control piston spring force in the direction of the first axial end installation and thereby determines a uniquely safe end installation. The valve has good dynamic properties.
