A safety valve for a cleaning device for a milking installation for milking milk-providing animals, including a first block valve with an input, a second block valve with an output, a bleed valve with a bleed output, a piston rod and a drive unit, wherein the safety valve is movable from a blocking position, in which the first block valve and the second block valve are closed in order to block the input and the output and in which the bleed valve is opened in order to connect the bleed output to a connection, into a pass-through position, in which the first block valve and the second block valve are opened in order to connect the input to the output via the connection and in which the bleed valve is closed in order to block the bleed output, and back. The first block valve, the second block valve and the bleed valve of the safety valve are designed as seat valves with a common piston plate.

A milking system includes a milking device for milking a milking from a dairy animal. The system is provided with a control unit for the milking system, milking cups, a first milk jar for receiving the milking, a first pumping device for pumping the milking from the first milk jar to a first milk pipe, a second milk jar in flow communication with the first milk pipe for receiving the milking from the first milk jar, and a second pumping device for pumping the milking from the second milk jar into a second milk pipe. The first pumping device is configured to pump the milking at a first flow rate and the second pumping device is configured to pump the milking at a second flow rate, which is lower than the first flow rate. The milking system also includes a heat-exchanging system in flow communication with the second milk pipe.

A quick-coupling device for a milking module of a milking system for milking dairy animals that forms a releasable and re-establishable connection between the milking module and a milk pipe and includes a valve mechanism for opening and closing a feeding port and a discharge port using a number of articulated clamps.

A milking system includes one or more milking devices and a control unit. The system is provided with a plurality of milking cups, a first milk jar for receiving the milking, a first pumping device for pumping the milking, a second milk jar for receiving the milking from the first milk jar, a second pumping device for pumping at least a part of the milking, and at least one storage tank for storing at least a part of the milking. The second pumping device pumps the milking at a lower flow rate than that at which the first pumping device pumps the milking. As a result, the milk is for the most part moved with low mechanical load and little admixture with air which improves milk quality. In the case of a plurality of milking devices in the milking system, various milkings can be moved and treated separately.

Milking clusters for a milking installation have four teat cups, each teat cup having a cup housing and a teat cup liner with a top region and a suction region. A connection for a milk tube is arranged at the cup bottom or at the end of the suction region of the teat cup liner. A mouth portion of a sterile air pressure line is arranged in the top region of the teat cup liner, through which pressure line sterile air is introduced at a volumetric flow rate greater than a fluid aspiration volumetric flow rate at the milk tube, such that a sterile air blanket is established in the top region of the teat cup liner. The milking clusters with the cup liner and sterile air blanket prevent milked milk from being contaminated by contaminants and microorganisms from the shed air, extending storage life for untreated raw milk.

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 milker unit short milk tube having a downstream milk claw connection end having a position and release device joined to and extending away from the downstream milk claw connection end; a controlled flexible portion disposed in an upstream direction from the position and release device; a reinforced portion disposed in upstream direction from the controlled flexible portion; and an interior milking claw inlet sealing surface.

A milking arrangement includes robot milking stations connected to a milk conduit with an outlet end. A connection conduit connected to the outlet end includes an outlet member. A cleaning device for cleaning the milk conduit includes a cleaning conduit having a first connection member. A milk tank includes a second connection member. The outlet member is movable between and connectable to the first connection member in a primary state, and to the second connection member in a secondary state. A controller communicates with the milking stations, the cleaning device and a user interface. When determined to change the state, measures for preparing the arrangement for the change are automatically performed. Thereafter, the user interface indicates to an operator that the arrangement is ready for the change.

A milking device including at least one milking cup with a teat space and a pulsation space, a pulsator connected by a pulsation line to the pulsation space of the milking cup and provided with a vacuum source, a vacuum line provided with a first controllable valve between the vacuum source and the pulsation line, an aeration line provided with a second controllable valve between the pulsation line and a source of higher pressure, and a pulsator control system for the first and second valves. The pulsator control system includes a flushing mode for opening and holding open the first and second valves during at least a predefined flushing time which is at least as long as the pulsation period.
