TEAT CUP Russian patent published in 2002 - IPC

FIELD: agriculture. SUBSTANCE: teat cup has milk pipe equipped with rigidity ribs arranged on its working part in different diametrical planes. Milk pipe is extended before each subsequent procedure of milking of group of cows (or individual cow) till springy members enter annular slot in teat cup casing. When negative pressure is supplied to teat cup cavity arranged under teat at atmospheric pressure in cavity between walls, working part of milk pipe compresses teat in different planes, in particular, in mutually perpendicular planes, because diametrical ribs have length equal to quarter the length of working part of milk pipe and are arranged along the length of it in mutually perpendicular planes. After milking, springy members are subjected to compression by applying force to corrugated member to urge springy members from slot, which results in the release of milk pipe from stress. EFFECT: increased efficiency and improved safety of milking process. 3 cl, 3 dwg
