TEAT CUP Russian patent published in 2017 - IPC A01J5/08 

FIELD: agriculture.

SUBSTANCE: device comprises a teat deformer installed between the housing and the teatcup. The deformer has the shape of lobes. The mechanism for driving the lobes is represented by a bellow with an annular partition and a spring-loaded valve in it. The upper annular bellow cover is made in the form of a piston sealed at the point of contact with the housing, forming an alternating vacuum chamber between the outer bellow wall and the inner housing wall, with a pneumatic drive from a pulsator. The under-teat chamber and the inter-walled chamber of the teat cup are connected to each other by openings in the lower part of the teat cup liner and connected to a source of low vacuum. The upper section of the bellow above the partition is communicated by openings in the outer shell with the alternating vacuum chamber between the bellow and the teat cup housing. The up stroke of the bellow piston is limited by an annular stop on the inner wall of the cup housing. One of the deformer lobes is rigidly fixed to the upper annular bellow cover and has a hinge for fastening the second lobe in the form of a double-armed lever. One end of the double-armed lever is connected to the racks of the bellow partition, and the second one contacts at the base with a teat through the teatcup liner.

EFFECT: increasing the efficiency of squeezing milk out of a teat.
