Abstract

The vacuum applied to the teat connection varies and alternates between a heavy and a slight vacuum. The interior of the teat connection is connected to the atmosphere by means of an air leakage point, and to the milk container which is kept under vacuum by means of a valve. The valve is constructed so that the vaccuum on the teat connection is roughly equal to the vacuum produced by the oscillating pressure source. The vacuum is a membrane valve, one side of the membrane being exposed to the pressure in the teat connection, and the other side to the pressure of the oscillating pressure source. The teat connection with chamber has a flexible seal.
