The milk machine works by having a collapsible '''liner''' within a solid '''pulsation chamber'''. The liner forms a seal at the top of the teat and connects with the '''short milk tube''' to deliver milk to the '''claw piece''' of the '''cluster'''. Via the '''short pulsation tube''', the pulsation chamber has an alternating vacuum/atmospheric air delivered which causes the milk liner to open and close beneath the level of the teat. When vacuum is present within the pulsation chamber, there is an equal pressure with that in the short milk tube, which has a constant vacuum supply to facilitate movement of milk away from the udder. The equal pressures means the liner is open and milk is drawn out. Conversely when atmospheric air is introduced into the pulsation chamber, the pressure differential causes the liner to collapse and the teat no longer to be exposed to the vacuum. This allows blood flow to return to the teat necessary to prevent teat damage and is called the '''massage phase'''. A constant vacuum applied to the teat, as in the early parlour designs, causes a vast amount of soft tissue trauma which would cause untold levels of mastitis.
