Abstract
A teat cup has an inflation with an intermediate portion sealed against the shell, defining a space adjacent the bottom of the shell, separate from the pulsation space. Holes through the shell and the inflation wall below the intermediate seal admit air to the inflation aiding the flow of milk. An air filter keeps dirt from the milk.
