Abstract

Automatic milking apparatus for hydraulic milking, in which there is no air bleed at or upstream of the clawpiece during milking of a cow. Each teat cup has a liner within the rigid teat cup shell which has a passage through which air may be admitted to the liner body from an air admission tube, at will after milking and before removal of the teat cups from the cow. The air admission tube runs from the linear body passage, between the liner and shell, through the pulse tube and into the clawpiece, where air admission is manually controlled.
