1.The design of milking machine imitates the movement which the calf is nursed, the vacuum  provides the power for the milking machine, the milk cup group is the instrument which completes milking directly.

2.The tubbish space between the milk cup sheath is called inter mural chamber, which is controlled by the connection of the short pulse tube and the pulsation.

3.Milking stage: In the seal vacuum system, the pressure of the milk cup inner sheath is equal to the inter mural chamber’s,which makes the inner sheath of milk cup open, when inter mural chamber is at the vacuum state, thus nipple cup draws out milk. As Figure 2 shows.

4.The rest stage: In the seal vacuum system, when the air enters the interspersed chamber, it will be a pressure difference between the milk cup inner sheath and the inter mural chamber, the milk cup inner sheath is closed, the milk flows stopped, it is the rest stage. As Figure 3 shows
