  • Patent number: 5161482
    Abstract: An automatic milking system milks cows using a combination of hydraulic and conventional milking techniques. The system has at least one teat cup which is placed over a cow's teat. Pressure in the teat cup is controlled to induce milking of the teat. The system has a regulator which maintains the pressure in the uppermost region of the teat cup at approximately atmospheric pressure throughout the milking process. In this way, discomfort to the cow and other adverse effects of the milking process can be avoided.
