ABSTRACT:
To accomplish this object, a device is designed and is characterized in that in the interior of the housing there is provided at least two baffle plates which are offset in the direction of the housing axis and between them form at least one third chamber and in that for the flow connection between the chambers a passage is provided in at least one baffle plate. Additionally, the device according to the present invention is characterized in that a switching means in the electric supply circuit for the magnetic coil has at least a third operating condition, in which the flow of current is interrupted by the at least one magnetic coil, and in that the switching means assumes this third operating condition in each instance between a first and a second or between a second and a first operating condition.
