Description

pa создаетс  противодавление, что преп тствует падению рабочего органа механизма. Это противодавление передаетс  в нагнетательную магистраль и золотник устанавливаетс  в равновесном положении, при котором давление в сливной полости гидроцилиндра не опускаетс  ннже того, которое необходимо дл  поддержани  механизма при его опускании . В рабочей же. полости гидроцилиндра давление соответствует усилию пружины, не создава  дополнительной нагрузки на насос на участке торможени , как это пронсходит во многих известных гидросистемах.pa creates back pressure, which prevents the mechanism from falling. This back pressure is transferred to the injection line and the spool is set in an equilibrium position, in which the pressure in the drain cavity of the hydraulic cylinder does not lower than the pressure needed to support the mechanism when it is lowered. In the working. The cavity of the hydraulic cylinder pressure corresponds to the spring force, without creating an additional load on the pump at the braking section, as is the case in many well-known hydraulic systems.

Дроссельные пробки 10 преп тствуют возникновению колебательных процессов при неустановившемс  движении золотника. При обратном ходе жидкости золотннк работает аналогичио.Throttle plugs 10 prevent the occurrence of oscillatory processes during unsteady movement of the spool. During the reverse course of the liquid, the gold works analog.
