MILK PUMP DEVICE AND METHOD FOR DISPLACING AN AMOUNT OF MILK

摘要

The invention relates to milk pump device (1), comprising a passage duct (10), a first one-way valve (11), a second one-way valve (12) and a membrane pump (20). The first and second one-way valves (11, 12) are included in the passage duct (10) and oriented in the same direction relative to each other. The membrane pump (20) is positioned between the first one-way valve (11 ) and the second one-way valve (12). The membrane pump (20) forms a first milk meter for generating a first milk measurement with respect to a number of complete pumping strokes of the membrane pump (20). The milk pump device (1 ) further comprises a second milk meter (30) for carrying out a second milk measurement with respect to a residual pumping stroke.
