METHOD OF MEASURING PRESSURE OF TEAT CUP LINER ON DUG DURING ITS CLOSING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC A01J7/00 G01L7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in production of, diagnostics of technical condition and maintenance of milking machines. To measure the pressure of teat cup liner on the dug when its closing the pressure is determined spent for deformation of the artificial dug, the excess air pressure is measured in the cavity of the artificial dug placed in the teat cup. The pressure of teat cup liner on the dug is determined as the sum of pressure spent for deformation of the artificial dug and the excess air pressure in the cavity of the artificial dug during the compression stroke of teat cup liner. The device for implementing the described method comprises a housing 1, an artificial dug 2, which inner cavity communicates with the pressure gauge 3 and the atmosphere through the valve 4, and the calibration unit of the artificial dug which comprises a chamber 5 with a nut 6, a pressure gauge 7 and a manual pump 8.

EFFECT: use of the invention enables to simplify and improve the accuracy of the method of measuring the pressure of the teat cup liner on the dug during its closing.
