MILKING UNIT

摘要

FIELD: agriculture. SUBSTANCE: milking unit has compression spring, adjusting screw adapted for compressing-straightening of spring for regulating vacuum gage pressure difference. Return valve for maintaining vacuum in cavities under teats at nominal value during compression cycle is formed as spherical device provided with conical depression disposed in the zone of contact between spherical device and channel. Such construction allows physiological features of each animal to be taken into account by creating predetermined adjustable vacuum gage pressure difference in chambers defined between walls and under teats of teat cup. EFFECT: increased efficiency and enhanced reliability in operation. 1 dwg
