In a connected state the first and second fluid systems (S1, S2) are in fluid communication with one another, and in a disconnected state the first and second fluid systems (S1, S2) are not in fluid communication with one another. The coupling arrangement includes a common cavity (CC) configured to be alternately included in the first fluid system (S1) or in the second fluid system (S2) for through passage of fluid while the first and second fluid systems (S1, S2) are disconnected from one another. The first fluid system (S1) also has a by-pass arrangement configured to allow fluid in the first fluid system (S1) to circulate independently from the passage of fluid through the common cavity (CC) when the common cavity (CC) is included in the second fluid system (S2).
Abstract:
An arrangement for controlling the supply of cleaning liquid into a milking system is provided. It comprises a pressurising arrangement (11, 31) adapted to pressurise the cleaning liquid, a supply arrangement (6, 7, 12, 13, 26, 40, 51, 53, 57) for selectively supplying cleaning liquid and a pressure sensing arrangement (27, 52) for sensing the pressure in the milking system. The pressure sensing device is operatively connected to the supply arrangement, and the supply arrangement is adapted to supply cleaning liquid into the milking system depending on the sensed pressure in the milking system. The arrangement can be adapted to supply cleaning liquid if the sensed pressure in the milking system is below the atmospheric pressure.

The invention concerns a method and arrangement of monitoring the supply of cleaning liquid from a cleaning line (1) to a milking system, where the milking system comprises at least two milking stations (4A-D) and milk conduits (2, 2A-D), and the cleaning line comprises supply conduits (3A-D) connectable to the milk conduits (2A-D) at the milking stations (4A-D) and arranged to apportion cleaning liquid to the milking stations, so that cleaning liquid flows through the milking stations. The method includes measuring a value of the flow of the cleaning liquid through the respective milking stations by means of a respective flow sensor (20A-D, 22, 26A-D) and transferring said values of the measured flows to a control unit (7, 17, 18). The arrangement further comprises a first control unit (7, 17, 18) and flow sensors (20A-D, 22, 26A-D) and a respective flow sensor is adapted to measure a value of the flows of cleaning liquid through a respective milking station (4A-D), and provide said values to the control unit (7, 17, 18). In this way the supply of cleaning liquid is monitored and a sufficient amount can be provided. Also, an unnecessarily large consumption of cleaning liquid can be avoided.
