A shutoff valve () is located in the connecting line (). The shutoff valve () is a check valve () that opens automatically and as a function of the pressure to allow a flow to the hydraulic accumulator (). A pressure relief valve () is operatively associated with the connecting line () between the shutoff valve () and the hydraulic accumulator ().
