A teat cup comprises a carrier liner, in the lower part of which it contains a circular silphon, the internal volumetric space of which is connected with an insulation chamber and an air piping of pulsating vacuum. On the silphon an additional liner with a stopper contacting the udder is mounted in such a manner as to allow longitudinal moving along the carrier liner in the upper part of said liner. The additional liner is made of the diameter larger than the diameter of the carrier liner. The cup also comprises a teat cup rubber pipe with a sucking cup in the upper part thereof and with a teat opening, the insulation chamber, formed between the carrier liner and the teat cup pipe, in which pulsating vacuum is set up and which is connected to the corresponding piping, mounted inside of the liner and connected with an air piping of constant vacuum, the stopper contacting the udder with an opening larger by the diameter as to an opening of the upper part of the teat cup pipe. |
