Abstract

W układzie hydraulicznym zawór przełączający (7) równolegle do połączenia w stanie otwartym z wyjściem (13b) zaworu zwrotnego sterowanego (13) połączony jest również dodatkowo przewodem (14a) aktywnym w innym stanie zasterowania zaworu przełączającego (7) z wejściem (13a) tego zaworu zwrotnego sterowanego (13).In the hydraulic system, the switching valve (7) in parallel to the connection in the open state with the output (13b) of the controlled non-return valve (13) is also additionally connected by a wire (14a) active in another state of control of the switching valve (7) with the input (13a) of this valve controlled return (13).
