Abstract
A milk pumping system used in vacuum milking installations for the purpose of withdrawing the milk that is in a vacuum milk receiver that is under constant vacuum, in cases wherein the milk must be pumped to a higher and more remote bulk tank that is under atmospheric pressure. For this purpose a milk releaser provided with a float is connected to the outlet of the vacuum milk receiver, and, when the milk releaser is filled up with milk, the float acts through a linkage to close a vacuum line connecting the first milk releaser to the vacuum milk receiver and establish a communication with the external atmosphere. The first milk releaser is in communication through an air line to an air-operated two-way valve, and the two-way valve is operated such that it is able to change a second milk releaser which is connected to the outlet of the first milk releaser and is under atmospheric pressure, to a vacuum, so that the milk that has collected in the first milk releaser can be aspirated out by the second milk releaser. The milk is let out of the second milk releaser into a bulk milk tank that is under atmospheric pressure.
