TEAT CUP Russian patent published in 1999 - IPC

FIELD: agriculture, in particular, milking equipment. SUBSTANCE: teat cup has casing and piston-type ejectors axially aligned with casing and positioned for displacement in radial direction. At least two piston-type ejectors are positioned in each row in equally spaced relation along casing perimeter. Piston cavities in rows are connected via channels which are opened in alternation. Upper row channels are provided with vent openings. Such construction allows ejector pressing force applied to animal's teat to be reducing from top to bottom. Combined animal's teat massaging and mechanical milk squeezing provide effective milking process. EFFECT: increased efficiency, wider operational capabilities and simplified construction. 2 cl, 2 dwg
