(under subclass 14.27) Milkers having the fluid pressure control associated with the cover of a receiver.
(1) Note. Compare with subclass 14.32 above. The fluid control means of this subclass 14.39 is distinguished from the trap chamber of subclass 14.32 by the fact that the control does not trap the milk and discharge it therefrom. The control in one position permits through vacuum and milk flow from the teat cup to the receiver and in an alternate position permits atmospheric air to relieve the pressure on the teat cup but does not disturb the vacuum in the receiver.
