A milk conduit, that connects to a teatcup to be attached to a teat of an animal to be milked, includes a first end portion defining a first end and configured to be connected to the teatcup, a second end portion defining a second end, and a conduit portion located between the first end portion and the second end portion. The milk conduit defines a milk channel extending through the first end portion, the conduit portion and the second end portion. The first end portion is received in an opening extending through a bottom wall of the teatcup. The first end portion includes a first circumferential groove configured that engages in the bottom wall of the teatcup.

The milking apparatus includes a cluster (4) connected to a retraction line (10), and a cylinder (11) having a piston (13) being movable between first and second end positions. The piston acts on the retraction line to move the cluster to a retracted rest position when moved to the second end position, and to permit the cluster to be moved to an active milking position when the piston is in the first end position. A switch device (30) may alternate between a first state and a second state. The retraction line permits the switch device to change from the first state to the second state when a movement of the cluster from the retracted rest position is initiated. The switch device initiates in the second state supply of a pressurized medium to the cylinder to force the piston to the first end position.

A cartridge and a teatcup to be attached to the teat of an animal to be milked are disclosed. The cartridge includes an elongated sleeve, having an upper end section and a lower end section, and a teatcup liner pre-mounted in the elongated sleeve. The teatcup liner includes an upper end portion located at the upper end section, a lower end portion located at the lower end section, and a barrel portion extending between the upper and lower end portions. The barrel portion has a polygonal cross-sectional shape defining a plurality of corner portions and a plurality of side portions. The elongated sleeve includes a primary locking member. The teatcup liner includes a primary complementary locking member. The two locking members engage each other to prevent rotation of the teatcup liner in relation to the elongated sleeve.

A milking apparatus is described that includes a longitudinally extending liner made from a resiliently deformable material. The liner is mounted on a rigid support shell. The liner comprises an outer hood configured to lie over an outer surface of the rigid support shell, and an inner barrel configured to be disposed within the rigid support shell and to define an internal volume. The inner barrel extends in the longitudinal direction away from an opening at a first end of the liner, through which opening an animal teat is insertable into the internal volume. The inner barrel is connected to the outer hood at a plurality of longitudinally extending connection regions on an inner surface of the outer hood. These connections define boundary conditions that limit the deformation of the barrel that encloses the teat can be set by the configuration of the liner itself.

A teatcup and a cartridge insertable into a connector of the teatcup to be attached to the teat of an animal to be milked are disclosed. The cartridge includes an elongated sleeve, having an upper end section and a lower end section, and a teatcup liner pre-mounted in the elongated sleeve. The teatcup liner includes an upper end portion located at the upper end section, a lower end portion located at the lower end section, and a barrel portion extending between the upper end portion and the lower end portion. The elongated sleeve includes three separate primary hook members provided circumferentially after each other on an outer surface of the elongated sleeve. Each primary hook member has a lower slide surface sloping upwardly and outwardly, and an upper hook surface extending inwardly.
