Abstract (en)

The component group of a pre-control valve and four switching valves has a 4/3 path valve as the pre-control valve. The pre-control valve has a housing with two control chambers (20,30), insulated from each other, and each with a working connection and two pressure connections. Two of the connections each have a seal seat (21,22;31,32). A switch unit moves in the housing. A seal (24,34) is in each chamber (20,30), to work with the seal seats on opening and closing. An operating unit moves the switch into three positions. The switch valves are membrane valves, to be operated by the pre-control valves.
