Abstract: A milking device for milking a dairy animal includes a teat cup with a cup wall and a teat liner and a pulsation space situated in between, to which pulsation space a pulsation device is connected which is configured to apply a pressure that varies in pulsations to the pulsation space in order to open and close the teat liner. The pulsation device includes a supply line which is controllable by a first operable valve, in particular closable, for supplying a first pressure, a supply line which is controllable by a second operable valve, in particular closable, for supplying a second pressure, which is a lower pressure than the first pressure, and a control unit which is configured to generate control signals for operating the first valve and the second valve, wherein the first valve, and preferably also the second valve, is a controllable valve having a passage which is adjustable by means of the control signals, wherein the passage of the first valve, and preferably of the second valve, respectively, is adjustable during at least one pulsation phase by the control unit via the control signals.

Abstract: A milking robot for the fully automatic milking of dairy animals includes at least one moving component and a cylinder configured to support a movement of the component. The cylinder has a cylinder wall having an aeration opening, as well as a cylinder rod slidable into and out of the cylinder. The cylinder wall surrounds at least one variable volume part, which volume part is free from pressure fluid connections for displacement of the cylinder rod. The cylinder is configured to remain, via the opening, substantially in pressure equilibrium with an environment of the cylinder. To the cylinder wall around the aeration opening is connected a gas collecting device which has a changeable volume and which, together with the variable volume part, forms an airtight gas volume. In addition, the gas collecting device has a minimum volume greater than zero.

Abstract: A milking robot for automated milking of milking animals, comprising a cylinder supporting movement of at least one movable component. The cylinder has a wall with a ventilation opening and a cylinder rod which can move in and out of the cylinder. The cylinder wall surrounds at least one variable volume part for movement of the cylinder rod. The opening configures the cylinder to remain in virtual pressure equilibrium with an environment. A gas capture device is connected which has a variable volume and which together with the variable volume part, forms an air-tight gas volume. Thus the variable volume part is kept at almost ambient pressure, so that no unnecessary counter-pressure occurs in the cylinder, during extension and retraction of the cylinder rod. Also less to no exchange of gas and dirt with the environment can take place for longer life and better reliability of the cylinder.

Abstract: An automatically cleanable milk filter includes a cylindrical housing with an outer wall, a first end with a first liquid connection, and above a second end with a second liquid connection. A concentric cylindrical filter part and a cylindrical core placed concentrically within the filter part are accommodated in the housing. The filter part includes wire having a tapered cross-sectional profile in a spiral shape or as a series of parallel rings or rods, and a frame for keeping them spaced apart, thereby forming a plurality of filter openings. The filter part divides the filter volume into a first volume part which is directly connected to the first liquid connection, and a second volume part which is directly connected to the second liquid connection. The second volume part includes a cylindrical part, as well as a top part which narrows at a transition to the second liquid connection.

Abstract: A milking system for milking of a milk animal, including a milking cup for obtaining the milk, the milking cup having a teat space with a first milk outflow opening, and a measuring chamber directly and rigidly connected to the milking cup for at least temporarily containing the obtained milk. The measuring chamber is provided with a milk inflow opening which is in flow communication with the first milk outflow opening, a second milk outflow opening, a vacuum outlet, and a sensor device for measuring a property of the milk in the measuring chamber. The sensor device includes an optical sensor device having a plurality of optical sensor elements, at least one light source, and a control unit which is configured to process sensor signals into values of at least two parameters of the milk in the measuring chamber.

Abstract: A milking system for milking a dairy animal includes a milking cup and a measuring chamber which is in flow communication with the milking cup for the obtained milk where the chamber has a sensor system for measuring at least one property of the milk. The sensor system includes at least three optical sensor devices, each configured to measure values of a property of the milk, and a sensor control unit for actuating the sensor system and for processing the measured values. The sensor control unit is configured to repeatedly select one of the sensor devices. Two of the optical sensor devices are identical, and the sensor system is configured to in each case measure the local value of the property of the milk and to determine a value of the at least one property of the milk in the measuring chamber on the basis of the values measured locally.
