FIELD: agriculture. ^ SUBSTANCE: invention refers to agriculture, in particular, to facilities for mechanisation of cows milking. Two-cycle milking unit of pairwise milking comprises double-chamber milking buckets, pulsator, milk vacuum hoses, header with milk-collecting chamber and chambers of alternating vacuum, hollow body with piston and dampers arranged in it. Hollow body is arranged in the form of toroid-shaped element with rectangular radial cross section and is equipped with additional piston. Dampers are fixed inside hollow body on nozzles-strainers in diametral and opposite manner. At both sides of the main and additional pistons there are two mutually isolated chambers, every of which is communicated with chambers of alternating vacuum of header and with wall-to-wall chambers of milking buckets, operating in opposite cycles. ^ EFFECT: milking unit complies with physiological requirements, provides for full extraction of milk without machine after-milking, makes it possible to increase operational reliability and purity of after-milking, and also facilitates operator's labour. ^ 3 cl, 2 dwg |
