TEAT CUP Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: teat cup has teat sleeve arranged inside casing fixed in body through quick-detachable connection, washer, shaped upper and lower rings provided with gauged channels and bores and arranged so that flows responsible for creating predetermined vacuum mode defining periodicity and intensity of action of teat sleeve upon udder teat are movable separately from milk mass to prevent fat from settling in air bores. Such construction allows teat sleeve to be continuous, without perforations. Circular diaphragm isolated from milk mass is put onto shaped upper ring to provide for periodic dosed supplying of air into teat cup cavity between walls. Automatic mode of extracting milk from cow udder allows milking mode for each udder quadrant to be varied depending on milk yield. EFFECT: simplified construction and increased efficiency. 4 cl, 4 dwg
