  • Patent number: 4378757
    Abstract: A milking method and machine are disclosed which serve to prevent back-spray of milk particles onto the teat tips of the animal's udder. The individual milk streams issuing from the milk orifices of the teats during intermittent application of suction to the teats are directed into a path leading to a milk collector. In this path, the streams flow in milk tubes which open into an elongated hollow connector that, in turn, communicates with a conduit. The discharge ends of the milk tubes are positioned in the connector at two or more locations which are spaced from one another, as considered in the direction of milk flow through the connector. An air stream is admitted into the connector to flow in a direction toward the conduit so as to accelerate the milk and prevent droplets of milk from being sucked back into the milk tubes during intermittent application of suction to the teats.
