Abstract: The invention relates to dynamic/wet testing of a milking machine (i.e. during extraction of milk from at least one animal). A proposed testing arrangement includes a number of sensors(111, 112, 113, 114, 121, 122, 123, 124, 2, 21, 22, 23, 24, 3, 31, 32, 33, 34, 4, 41, 42, 43, 44, 5, 6), which are adapted to register a vacuum pressure at a respective test point in at least one fluid conduit of the milking machine. An analysis unit (A) of the testing arrangement determines at least one pressure difference between the vacuum pressures registered in at least two of the test points being positioned on a respective side of at least one component in the milking machine with respect to a fluid flow through the at least one component to establish a vacuum drop over this component. The unit (A) compares the vacuum drop with a threshold value to conclude whether or not a test condition is fulfilled. A notification is generated with respect to any component for which the condition not is fulfilled.

Abstract: The present invention relates to a method and a milking machine comprising at least one teat cup for application to a teat of an animal to be milked, a teat cup liner, mounted in said teat cup, defining a teat receiving space inside said liner, and a pulsating chamber between said liner and said teat cup, said liner having a teat receiving end portion, a vacuum source for applying a vacuum level to the teat receiving space for drawing milk from said animal, a pulsator for application of a pulsating vacuum to the pulsating chamber for moving the teat cup liner between a closed position and an open position, thereby massaging said teat of said animal, and a vacuum sensor for sensing the vacuum level in said teat receiving end portion. The invention is further characterized in that said milking machine is arranged to initiated take off of said at least one teat cup, if a vacuum level sensed by said vacuum sensor indicates that the vacuum level in said teat receiving end portion is rapidly increasing.

Abstract: In a milking machine having a teatcup (3) with a teatcup liner (6) and a pulsation chamber (7), the abrupt movement of the teatcup liner (6) when the teatcup liner moves to an open or closed position is sensed. If the sensed movement does not fulfill a predetermined condition, a malfunction is signaled.

Abstract: In a milking machine having a cluster (2) with a number of teatcups (3) each teatcup (3) having a teatcup liner (6) and a pulsation chamber (7), the abrupt movement of the teatcup liner (6) between an open and a closed position is sensed. This sensed movement which is an indication of the milk flow is used to control the milking intensity.

Abstract: A milking machine having a teatcup (3) with a teatcup liner (6) and a pulsation chamber (7), the pulsating vacuum level is determined when the teatcup liner (6) abruptly opens or closes. At least one of the milking vacuum and the pulsating vacuum is controlled such that the maximum level of the pulsating vacuum is lower than the milking vacuum level and at least as high as the determined level.

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).
