CA 2083152

A milking pulsator (11) comprises a housing (12), forming a chamber (14), in which a vacuum passage (39) opens via a first opening. A pulsation channel (33) to be connected to at least one teat cup communicates with the chamber and with atmosphere via a second opening (35). Valve means (21, 22) are arranged to close and open said first and second openings. Each valve means comprises a membrane (25, 26), and a pivoted member (29, 30), the membrane being attached between the pivoted member and the housing (12). The pivoted members are journalled in the housing for pivotal motion back and fourth between closing posi- tions, at which said openings are covered by the membranes of the valve means, and opening positions, at which said openings are uncovered. In addition, adjustment means (47, 48, 49) are adapted to adjust the pivoted members of the valve means such that the first opening is closed when the second opening is uncovered and vice versa.
