  • Patent number: 6543382
    Abstract: A milking claw includes a milk bowl with an interior having an inner bottom surface, an inner top surface and an inner sidewall surface between the inner top and bottom surfaces. Milk inlets are formed in the bowl and open into the interior of the bowl through the inner top surface and are connected to milk hoses leading to the teat cups. A hollow outlet tube is mounted to the bowl with an intake end spaced above and closely adjacent to the inner bottom surface of the bowl. The outlet tube extends upwardly and sidewardly from the intake end within the interior of the bowl, and extends through the inner sidewall surface to an exit end outside of the bowl. The outlet tube is preferably smoothly curved within the interior of the bowl so that milk is drawn out of the bowl with minimal turbulence and reduced vacuum pressure drop.
