Abstract: When designing the structural and functional schemes of the vacuum systems of a portable milking machine it is important to conduct a research on the impact on the milking machine efficiency. The technological efficiency and the regime of a vacuum system functioning are the basis of the research. The unstable pressure may cause the decrease in animals productivity and may have negative impact on cows welfare. That is why it is necessary to determine some rational parameters and choose the linking vacuum system decisions. It will result in getting stable working regimes of a portable milking machine. A research on the effects of different components variants as well as of vacuum system parameters on the consistency of operation has been conducted. The results of the research made it possible to estimate the impact of vacuum pump fast reaction as well as the vacuum system parameters on the job stability. It has been proved that the vacuum system efficiency is determined by the level of its conductivity. The conductivity is the inverse value to the vacuum system resistance. The research has determined how the vacuum system packaging affects the pressure loses. A mathematic model which enables to find the rational volume of a vacuum pump and determine the vacuum system conductivity has been received. On the results of the experimental research the vacuum system rational structure has been substantiated and estimated on a special efficiency coefficient
