TEAT CUP OF SQUEEZING PRINCIPLE OF ACTION

摘要

FIELD: agriculture.;SUBSTANCE: teat cup of squeezing principle of action comprises a housing 1 with a nipple tube 2 and a deformer 23 for squeezing the nipple base driven by the piston 7. The deformer 23 is made in the form of the plates 24, 25, one of which 24 is rigidly fixed by means of racks 26 on the rods 10 of the piston 7, the second plate 25 is fixed to the levers 27 pivotally mounted on the rods 10 and extending through the support rings 28. The piston 7 of the cylinder 6 by means of two rods 10 extending through the housing 1 is rigidly connected to the lever 11 of the valve 12 of the pressure switch 13, located on the opposite side of the teat cup. The chamber 14 of the pressure switch 13 through the opening 15 in the housing 1 is communicated with the intermural chamber 16 formed by the nipple tube 2 and the housing 1 of the cup. In the housing 17 of the pressure switch 13 the opening 18 is made for communicating of its chamber 14 with the cavity of the milk pipe 4, and an opening 21 for accessing the overpressure overlapped in the initial condition by the flap 12.;EFFECT: invention reduces the incidence of mastitis in cows.;1 dwg
