Abstract

Each control unit (1,1') comprises an effect valve (6), which is spring-loaded in the direction of a first end position and which is drivable to a second end position. The two effect valves (6,6') are coupled in series between a fluid pressure source and a receiver (10) of pressurised fluid, for feeding the receiver with pressure fluid when both effect valves are in their second position. Each control unit has a monitoring valve (7,7') which is tensioned towards its one end position. It is movable against this tension to its opposite end position. Each monitoring valve in its one movement direction is movable by a fluid pressure flow regulated by the effect valves. Each monitoring valve is movable to its second end position when the corresponding control unit effect valve has adopted its second end position.
