A method for mechanical milk removal in which a predetermined underpressure is applied to the interior of a milking cup applied to a teat to remove the milk and, if desired, a pulsation of a teat rubber is effected at a predetermined frequency and intensity, and while the milking cup is in place the teat is stimulated for a predetermined interval prior to the principal milking operation. The invention also relates to an apparatus for executing the method comprising a pulsator connected on the one hand to an underpressure source and on the other hand to pulsator lines supplying the pulse spaces of the milking cup, the pulsator having two membranes which are interconnected by a linkage and which subdivide each pressure cell into two separate spaces, two spaces of which communicate with one another via a throttle, if desired adjustable, while the two other spaces of which are adapted to be selectively connected via a control unit to the underpressure source, and further comprising a switch-over device which is connected to the linkage and which serves to selectively connect one or two group(s) of pulsator lines to the underpressure source and to fresh atmospheric air. |
