A system and method for verifying proper milking system performance during the milking process. The system and method incorporates an integral function within a pulsator valve device that routinely performs functional evaluations and is capable of reporting results to the user. An additional air valve apparatus can be used to supply additional air to the pulsator valve device.

There is provided a milking cluster (102) for milking an animal, the milking cluster comprising a plurality of teat cups (1) connected to a clawpiece (106). The clawpiece comprises a plurality of milk inlets that are connected to the plurality of teat cups via respective short milk tubes (11). A milk flow passageway begins at the barrel of the teat cup and ends at the clawbowl of the clawpiece, and a valve system is present within each milk flow passageway. The valve system comprises a first pressure-actuated valve through which milk flowing along the milk flow passageway must pass.

A teat dip fluid manifold and methods for distributing teat dip fluids, and including redundant valve sets and pressure monitoring between valve pairs to determine valve condition.

A method for sampling milk in a milking machine includes the steps of attaching teat cups to teats of an animal and starting to milk said teats; receiving a first amount of milk in a milk receiver while keeping an outlet valve device open; closing the outlet valve device; continuing the receiving of milk in the milk receiver; agitating the milk in the milk receiver using an agitation device of a milk sampling arrangement; taking a regular milk sample from the milk in an outlet portion of the milk receiver using a milk sample device of the milk sampling arrangement; and opening the outlet valve device so that the milk can be transferred to a milk tank.

A docking device, for a milking parlor with a rotary platform and a plurality of milking stalls, includes a first docking unit with a part of a first milk line connected to the platform and a second docking unit with a part of a second milk line separately arranged from the platform. At least one of the docking units includes an adjusting mechanism allowing an adjustment of a position of said docking unit in relation to the other docking unit. At least one of the docking units is associated with a guiding surface configured to guide the other docking unit during the movement in order to reach the docking position in which a closed connection is provided between the outlet opening of the first docking unit and the inlet opening of the second docking unit.

A milking arrangement with a plurality of milk stations connected to the milk transport line, a receiver connected to the transport line that receives milk transported from the milk stations via the transport line, and a vacuum system that supplies a vacuum in the transport line via the receiver, with a cleaning liquid source connected to the transport line, a controllable injector that introduces an amount of gas into the transport line to produce a temporary pressure increase therein that causes a slug of a cleaning liquid from the cleaning liquid source to be formed and forwarded through the transport line, and a control system configured to control the operation of the injector, wherein the control system is configured to control characteristics of the slug by controlling the vacuum level supplied by the vacuum system and/or the amount of gas introduced via the controllable injector.

An apparatus that includes a housing with an input port and a first output port. A piston is disposed within a bore of the housing and includes a bypass via disposed transversely within the bore and a bypass tube disposed longitudinally within the bore. The bypass tube is configured to provide a flow path from the bypass via to a second output port on the bypass tube. The piston includes a sleeve disposed concentrically around the bypass tube. An interior chamber is defined by an exterior surface of the sleeve and an interior surface of the bore of the housing. The piston is configurable between a first configuration that provides a first flow path between the input port and the first output port via the interior chamber and a second configuration that provides a second flow path between the input port and the second output port via the bypass tube.

The invention relates to a milking unit comprising a milk collection part and at least two milk tubes that are connected to the milk collection part. At least one end of the milk tube has an essentially spherical clamping body, the central point of the clamping body being offset in relation to the longitudinal axis (S) of the milk tube and/or the clamping body having a channel with a mouth. The longitudinal axis (S) penetrates a plane, on which the cross-sectional surface of the mouth lies at an angle that is not equal to 90°.
