The following components are installed in the vacuum reducer - a control valve, two throttling holes, a stop valve and a magnetic valve for periodical communication of the bellow and the lower cavity of the vacuum reducer between each other. The stop valve has a snap mechanism and a spindle, and separates the vacuum reducer into two cavities. The above-membrane cavity of the receiver is connected to the upper cavity of the vacuum reducer for switching of milking modes. The control valve is connected to the receiver's float with the help of a sliding stem comprising a flag for interaction with the stop valve. The first throttling valve is installed in the pair with the stop valve, the second one - in the lower cavity of the vacuum reducer body in the pair with the control valve. The magnetic valve is installed in the lower part of the vacuum reducer's body, besides, one of the magnets is attached to the control valve.

EFFECT: invention provides for timely disconnection of the milking apparatus after the end of milk surplus, expands assortment of milking apparatuses with three-phase milking mode.
