ABSTRACT:
A cylindrical chamber in the pulsator housing has upper and lower end portions subjected continuously to atmospheric pressure and to a vacuum, respectively; and the pulsation spaces of the teat cups are connected to corresponding openings in the housing which lead from a region of the chamber located between its said end portions. These end portions are separated from each other by a rotor driven on the cylindrical axis of the chamber and having a peripheral surface engaging the chamber's cylindrical wall substantially continuously around the axis. The rotor has segments spaced from each other and forming parts of said peripheral surface which are located, respectively, above and below said region of the chamber openings, whereby each said pulsation space is subjected alternately to atmospheric pressure for a first time period and to vacuum for a second time period; and the ratio of these time periods can be varied by adjusting the rotor axially in the chamber.
