The protection circuit has solenoid valves (1.2, 1.3) interconnected to another solenoid valve (1.1). Control valves e.g. cartridge valves, (2.1, 2.2, 3.1, 3.2) are connected in parallel to each other such that a large flow rate is controlled with their simultaneous opening through the controlled solenoid valves. The valve (2.1) affects an actuation bearing (9), by simultaneous control of the solenoid valves (1.2, 1.3). An independent claim is also included for a procedure for an operation of a protection circuit. |
