  • Patent number: 10548291
    Abstract: A teatcup includes a sleeve, a teacup liner provided in the sleeve, and a milk receptacle including a milk space. An inlet channel extends between an inner space of the teatcup liner and the milk space for conveying milk from a teat into the milk space. An outlet channel extends from the milk space and is connectable to a milk conduit for conveying the milk in a milk flow from the milk space. A gas supply channel conveys a gas into the milk space for promoting the milk flow. The gas supply channel has an inlet communicating with a gas source, and an outlet into the milk space. The milk space is partly delimited by a side wall. The gas supply channel extends within the side wall and along a surface of the side wall.

  • Patent number: 6860228
    Abstract: The present invention relates to a milking cup comprising a cup sleeve, a teat rubber inserted in the cup sleeve with a head piece and an intake socket connectable with a milk discharge conduit, and comprising an air inlet valve provided on the milking cup and connected with the interior space of the intake socket via a first conduit, which lets atmospheric air penetrate into the intake socket in response to a relief phase, during which a higher pressure causing a folding-in of the intake socket relative to the milking vacuum pending in the milk discharge conduit is generated in a clearance between the cup sleeve and the intake socket. The invention is characterized in that an opening toward the interior space of the teat rubber is provided in the head piece of the teat rubber, wherein the opening can controllably be supplied with atmospheric air in response to the relief phase.
