FIELD: agriculture, in particular, vacuum regulating equipment used in milking units. ^ SUBSTANCE: vacuum regulator has casing with side air suction openings, valve mechanism with stem arranged in outer guide, and stop adjustable along stem length. Tore-shaped aneroid box is located between casing connecting member and stop and adapted to serve as spring owing to its resilient properties. Outer gas pressure causes changing of spring resiliency depending on changing of atmospheric pressure of environment. Correction of vacuum degree maintained in vacuum pipeline depending on changing of atmospheric pressure improves sensitivity of udder teat to the action of teat cup rubber and provides for complete lactation reflex, especially on abrupt changing of atmospheric pressure of environment. ^ EFFECT: increased efficiency and enhanced reliability in operation. ^ 2 dwg |
