Suction conduits (6,7) lead from the suction unit (1) to the reception containers (2,3). The suction unit comprises two chambers (A,B) in which alternatingly a vacuum is produced, and to which each of the two suction conduits is connected. In each suction conduit a vacuum is alternatingly produced, which activates the suction of mother milk. The suction unit incorporates a double-acting work cylinder (4), the two work chambers of which are connected to the suction conduits. The piston (5) of the work cylinder is drivable manually or by motor. |
