A breast milk pump suction arrangement includes a suction pump with suction connections, a fellow breast connector, a reservoir connected to the funnel and a pulsator. The suction pump is connected to the pulsator by a first suction line and a reservoir is connected to the pulsator by a second suction line. The pulsator includes a cylindrical housing supporting a control element which is moveable within said cylinder. The control element defining an air chamber and a vacuum chamber. The vacuum chamber being in communication with the first suction line and the second suction line. An opening in said cylinder providing communication between said air chamber and atmosphere. An air intake valve is provided to vent the vacuum chamber to atomsphere periodically by opening and closing a valve closing element. A transmission arrangement is provided, connecting the control element and the valve element. The transmission arrangement includes a delay for delaying the closing of the valve element upon movement of the control element in a closing direction.
