Description

one

This invention relates to agriculture, in particular to milking apparatus pulsators.

The purpose of the invention is to simplify the design and operation of the pulsator.

The drawing shows a diagram of the pulsator of the milking machine.

The pulsator of the milking machine contains a cylindrical body 1 with a ball valve 2, a calibrated orifice 3 constant vacuum, an orifice 4 atmospheric pressure and an alternating vacuum outlet 5, with the constant vacuum orif 3 located in the center of the upper end 6 of the cylindrical body 1, and the orifice A atmospheric pressure at bottom 7.

8, a side wall 8 of the cylindrical body 1, a channel 9 is made with re-. gulirovany screw 10. In this case, the inlet 11 of the channel 9 is located from the upper end 6 of the cylindrical body 1 at a distance greater than the radius of the ball valve 2, and the outlet of the 12th channel

9- between the inlet 11 and the vacuum hole 3 flush with the variable vacuum hole 5.

The milking machine's pulsator works as follows.

A vacuum is applied through the calibrated orifice 3 of a constant vacuum. Inside the pulsator case 1, a vacuum is created, through the outlet bushing-. Tie 5 variable vacuum coming into the interstitial chamber of teat cups (not shown in the drawing). There is a tact suck. When a certain value of vacuum is reached, the force acting on the ball valve 2, created by the pressure difference, becomes greater than its weight. The ball valve 2 rises up, closes the calibrated orifice 3 of a constant vacuum and opens the atmospheric orifice 4.

Atmospheric pressure through the inlet 11 of the channel 9 with the adjusting screw 10 enters the inside of the upper part of the pulsator body 1 and through the aperture 5 of the alternating vacuum enters the interstitial chamber of teat cups (not shown). There is a tact of compression.

The ball valve 2 is under the action of gravity (as it is no longer affected by the pressure difference force}) and the work cycle is repeated. The adjusting screw 10 adjusts the duration of the compression stroke.

Claims (1)

PULSATOR OF THE MILKING MACHINE, including a cylindrical body with a ball valve and a constant vacuum hole, made calibrated, and an atmospheric pressure hole, as well as an alternating vacuum outlet, the constant vacuum hole located in the center of the upper end of the cylindrical body, and the atmospheric pressure hole in the lower end of the cylindrical body, characterized in that, in order to simplify the design and operation, a channel with an adjustable paid-in screw, wherein the inlet channel is disposed from the upper end of the cylindrical body at a distance greater than the radius of the ball valve and the outlet of said channel - between the inlet orifice and the vacuum housing flush with an opening _of variable vacuum. ©>
