Method and device for improving milking vacuum near a teat of an animal to be milked

摘要

The teat cup (1) is connected to the milk line (47) through a pressure sensor (6) and a check valve (5). In a comparator (7) the pressure recorded by the sensor is compared with a specific reference pressure for a control unit (8) which controls the check valve to vary the cross section of the hose (4) connected to the cup.
