PNEUMATIC PULSATOR FOR MILKING UNITS Russian patent published in 2011 - IPC A01J5/12 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of livestock farming and may be used for machine milking of cows. The device comprises a driving oscillator of vacuum pulses and a repeater with shift combined into a single structure, having the common chamber of atmospheric pressure. The common chamber is connected by fly gates to valve chambers of the pulse driving oscillator and the repeater, having a single outlet towards each pair of milking sleeves, and with the permanent vacuum chambers of the generator and the repeater. The valve chamber of the generator is connected, at one side, via an alternating throttle with its command chamber, and at the other side, with the repeater's chamber. Simultaneously the command chamber of the generator is connected to the repeater chamber separated at one side with an atmospheric pressure membrane, and at the other side separated by a membrane from the permanent vacuum chamber. All repeater membranes are connected by a common stem with its valve. Efficient areas of membranes are calculated so that the end of the generator vacuum pulse is the start of the repeater vacuum pulse, the end of which complies with the half of time of the generator vacuum pulse duration. The pulsator executes the paired work of milking sleeves with the optimal time cycle.

EFFECT: improved efficiency of milking.
