ELECTROMAGNETIC PULSATOR OF THE MILKING MACHINE IN PAIRS Russian patent published in 2022 - IPC A01J5/14 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to milking machine pulsators. SUBSTANCE: electromagnetic pulsator of the paired milking machine contains a body (1) with constant (6, 7) and variable (8) vacuum nozzles, an atmospheric channel (9) with a filter (12), a valve mechanism connected to an electromagnet. In the alternating vacuum chamber, a cone valve (18) is rigidly fixed at the end of the shaft of the linear electric motor, and a bottom valve (20) in the form of a disk is located on the sliding fit, blocking the constant vacuum chamber in the lower position of the electromagnet armature and opening the constant vacuum chamber by means of a stop (21) at the top position of the anchor. The housing contains an electronic control unit (4) driven by a motor-reducer (2), a valve mechanism consisting of cone valves (18), each of which is equipped with a fixing spring (19) and is configured to control the smoothness of downward movement by changing stiffness of the fixing spring by screwing into the link (17) of the crank-link mechanism (3).

EFFECT: reliability of working surfaces increases, the air consumption for the drive of the milking machine decreases.
