摘要：
In a method and a configuration for operating a hydraulic drive, a 3/2-port directional seat valve, which is driven by solenoid coils, controls an application of high-pressure fluid through a working piston of a piston/cylinder system. In order to increase the circuit-breaking capacity of the working piston, a hydraulic booster valve which is driven hydraulically by the 3/2-port directional seat valve is used for clearing a direct path from the piston/cylinder system to the low-pressure reservoir during switching-off.
