A dual-mode milking machine consisting of four modules (a twophase milking machine for milking in pairs, a module for quarter controlling the milk flow intensity, an electrical pneumatic block, and a milk pneumatic valve) has been designed. If the milk flow intensity in any quarter of the udder is low (less than 50cm3/ min) the milking machine works in the three-phase regime of simultaneous milking. If the milk flow intensity in all quarters is higher than 50cm3/min, the milking machine automatically switches to the two-phase regime of milking in pairs.
