ABSTRACT:
Apparatus used in conjunction with milking machines for automatically stimulating the cow to facilitate milk let-down. Upon initiation of the milking cycle, the apparatus provides a controlled higher than atmospheric pressure to the air intake port of the vacuum line pulsator. An alternating vacuum and air pressure is thereby applied between the teat cup shell and inflation to provide a massaging action which causes stimulation of the cow and full milk let-down. Timing means are provided in the apparatus to shut off the air pressure to the pulsator a selected period of time after initiation of the stimulation, and to thereafter supply filtered atmospheric air to the pulsator to allow milking to continue in the usual manner.
