The paper presents ranges of negative pressure fluctuations in the teat chamber of a cluster in the Fullwood pipeline machine for milking goats. Investigations were carried out at different points of the pipeline at variable number of clusters, what allowed us to determine the influence of these parameters on negative pressure fluctuations. On the basis of the obtained results we came into conclusion that the number of clusters influences negative pressure fluctuations in the teat chamber, which are caused by the clusters, and pecorded negative pressure fluctuations are in the range of 0 - 40 kPa (at nominal pressure 36 kPa).
