  • Method of milking an animal and a milking machine
    Patent number: 5970910
    Abstract: A milking machine (1) comprises at least one teatcup (2) having a teatcup liner (4) and a pulsation chamber (5), a first pressure source (14) for generating a first pressure, a second pressure source (9) for generating a sub-atmospheric second pressure, which is lower than the first pressure, and conduit means (12, 15, 13) for transmitting the first pressure and the second pressure, respectively to the pulsation chamber (5). A pulsator (11) is provided for alternately connecting the first pressure source (14) and the second pressure source (9) to the pulsation chamber (5).
