Abstract
Means acting upon the flow, such as pumps or valves are used inter alia in the handling of liquid foodstuffs, e.g. milk, in packing machines. Since the demands on hygiene in this context are very high, especially if the packing machine operates with foodstuff sterilized beforehand, it is a disadvantage that manoeuvering devices for the means acting upon the flow have to pass from the outside into the sterile flow path where the means is located. This is avoided in accordance with the invention in that the means (3) acting upon the flow is combined with an actuator (8) which can be acted upon electromagnetically by a stator (7) isolated from the flow path.
