PULSATOR OF MILKING MACHINE Russian patent published in 2015 - IPC A01J5/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for converting constant vacuum pressure into pulsating, and can be used in the construction of machines for milking cows. The pulsator is made in the form of two power chambers 1 and 2 rigidly connected to each other. Each chamber 1 and 2 is formed as pneumatic 5 and 6 and hydraulic 8 and 9 chambers separated by flexible membranes 3 and 4. The hydraulic chambers 8 and 9 are interconnected by the calibrated tube 7 and filled with the viscous fluid and magnetically operated physico-mechanical properties. The pulsator is provided with two solenoid coils 10 and 11 mounted coaxially with a calibrated tube 7, which are adjacent to the outer sides of the hydraulic chambers 8 and 9, and connected alternately by the spool-type switch 12 through the control unit 13 to the source of electrical energy.

EFFECT: pulsator provides reliable control of the switching frequency of the modes of operation of the teat cups of the milking machine.
