Abstract

Siłownik hydrauliczny z układem blokującym swobodne przemieszczenie elementu roboczego siłownika zwłaszcza w przypadku spadku ciśnienia w przewodach zasilających wynikającego na przykład z ich uszkodzenia, zbudowany z cylindra (1), w którym osadzony jest element roboczy siłownika w postaci nurnika albo złączonego z tłoczyskiem (2) tłoka (3), przy czym każda z komór roboczych (4, 5) siłownika połączona jest tłoczną linią hydrauliczną (6, 7) z zaworem zwrotnym sterowanym (8, 9) charakteryzuje się tym, że zawór zwrotny sterowany (8, 9) każdej komory roboczej (4, 5) umiejscowiony jest w bloku cylindra (1), a każda tłoczna linia hydrauliczna (6, 7) ma postać utworzonego w bloku cylindra (1) wewnętrznego kanału.Hydraulic cylinder with blocking system free movement of the cylinder's working element, especially in the case of pressure drop in supply lines resulting from, for example, their damage, built of a cylinder (1), in which the cylinder's working element is mounted in the form of a plunger or piston rod (2) (3), each of the working chambers (4, 5) of the actuator is connected by a pressure hydraulic line (6, 7) with a controlled check valve (8, 9) is characterized by the fact that the controlled check valve (8, 9) of each chamber working (4, 5) is located in the cylinder block (1), and each pressure hydraulic line (6, 7) has the form of an internal channel formed in the cylinder block (1).
