Piston Type Single Bucket Milking Machine

When the pulsator slides over and suction is applied to the teat and the teat cups try to climb up and swallow the teat just as they do on any milking machine, butthe instant the pulsator slides the other way and the suction eases, the freely swinging unit pulls them right back where they belong.The principle of machine milking is to extract milk from the cow by vacuum. The machines are designed to apply a constant vacuum to the end of the teat to suck the milk out and convey it to a suitable container, and to give a periodic squeeze applied externally to the whole of the teat to maintain blood circulation.
