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). Influencing means (26) is provided for influencing the transmission of at least one of the first pressure and the second pressure to the pulsation chamber (5) such that the efficiency of said pressure transmission is relatively high when the momentary pressure in the pulsation chamber (5) is higher than an intermediate pressure and is relatively low when the momentary pressure in the pulsation chamber equals to or is lower than said intermediate pressure.
