MILKING DEVICE ELECTROMAGNETIC PULSATOR Russian patent published in 2020 - IPC A01J5/14 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to pulsators of milking plants. Electromagnetic milking device pulsator comprises a body with permanent and variable vacuum branch pipes, an atmospheric channel with a filter, a valve mechanism connected to an electromagnet. In the vacuum chamber at the shaft end of the linear electric motor the conical valve is rigidly fixed. On the sliding landing the bottom valve in the form of the disk is located, covering the chamber of constant vacuum at the lower position of the armature of the electromagnet and opening the chamber of constant vacuum by means of a stop at the upper position of the anchor. Housing comprises top and bottom covers. Atmospheric channel is made in upper cover of housing and is equipped with O-ring of round section. Conical valve is equipped with a fixing spring and is made with possibility of adjustment of smoothness of movement downwards by means of change of rigidity of fixing spring by screwing of shaft into anchor of electromagnet. Electromagnet consists of a coil and of a fixed magnetic conductor fixed in the case with the lower cover.

EFFECT: reduced air consumption during operation of milking machine, simplified design of pulsator, increased reliability of pulsator.
