TEAT CUP Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: teat cup has annular membrane fixed to teat sleeve and inside teat cup casing and sensitive to teat resiliency, and membrane valve for closing channel communicating cavity around teat cup with atmosphere. Gaged channel formed in teat cup casing is adapted for continuous discharge of air from said cavity into vacuumized milk pipeline. During milking, changing in teat resiliency results in changing deformation extent of annular membrane. Accordingly, vacuum gage pressure in cavity above membrane acting upon membrane valve is altered in direct proportion to teat resiliency. Increase in vacuum gage pressure inside cavity above membrane results in decrease of vacuum gage pressure in cavity around teat in reverse proportion to teat resiliency. Resultant vacuum redistribution between cavity under teat and sucker provides immobility to teat cup relative to udder teat during the whole milking time. EFFECT: increased efficiency and improved milking process. 2 dwg
