Устройство управления объемным потоком гидравлической рабочей среды имеет запорный клапан, в котором расположено тело седельного клапана, взаимодействующее с седлом основного клапана. В теле седельного клапана расположен элемент клапана вспомогательного управления, который взаимодействует с седлом клапана в теле седельного клапана. Благодаря воздействию давления в камере сжатия на одной из торцовых сторон тело седельного клапана прилегает к седлу клапана. С помощью дросселя эта камера сжатия соединена с рабочим цилиндром. Через переменное место дросселирования управление поперечным сечением отверстия которого осуществляется с помощью элемента клапана вспомогательного управления, а также пропорционального магнита, можно воздействовать на давление в камере сжатия и тем самым на положение тела седельного клапана в запорном клапане. Это положение тела седельного клапана в запорном клапане определяет поток рабочей среды от рабочего механизма (рабочего цилиндра) к резервуару.The control device of the volumetric flow of the hydraulic working medium has a shut-off valve, in which the body of the seat valve is located, which interacts with the seat of the main valve. In the body of the saddle valve is an element of the auxiliary control valve, which interacts with the valve seat in the body of the saddle valve. Due to the pressure in the compression chamber on one of the end sides, the body of the seat valve is adjacent to the valve seat. Using a throttle, this compression chamber is connected to the working cylinder. Through a variable throttling site, the cross section of the orifice is controlled by the auxiliary control valve element as well as by the proportional magnet, it is possible to influence the pressure in the compression chamber and thereby the body position of the seat valve in the stop valve. This position of the saddle valve body in the shut-off valve determines the flow of the working medium from the working mechanism (working cylinder) to the tank.
