MILKING CUP FOR MILKING MACHINES

摘要

The invention relates to a milking cup (1) comprising a cup sleeve, a teat rubber element (3) inserted into said cup sleeve having a head piece (4) and a suction pipe (5) that can be connected to a milk extraction line, in additio n to an air inlet valve (13) that is provided in the milking cup (1) and is connected to the interior of the suction pipe by a first line (14). Said val ve allows atmospheric air to enter into the suction pipe depending on a dischar ge phase during which a pressure that is higher relative to the milking vacuum being applied in the milk extraction line is generated in the intermediate space (12) between the cup sleeve (2) and the suction pipe (5), said pressur e causing the suction pipe to fold. The invention is characterized in that an opening (25) toward the interior of the teat rubber element (3) is provided in the head piece (4) of said teat rubber element (3), wherein the opening (25) can be controlled with atmospheric air depending on the discharge phase.
