<p>In a method of automatically milking animals, such as cows, use is made of teat cups, each of which is provided with a liner made of a flexible material, by means of which the teat space of a teat cup is separated from the pulsation space. During milking, a pulsating vacuum stimulating the milk yield is created in the pulsation space. When a teat cup is being connected to a teat, the pulsation space is kept at an approximately atmospheric pressure, while air is extracted from the teat space. Conversely, when a teat cup is being disconnected, in the pulsation space a vacuum is maintained and in the teat space the vacuum is neutralized. <IMAGE></p> |
