Abstract

1506636 Milking machines ALFA LAVAL AB 5 June 1975 [14 June 1974] 24274/75 Heading AIM The teat cup pulsation chambers 6b, 7b are subjected to a reduced pulsation vacuum when the milk flow drops below a predetermined level. To achieve this, a valve arrangement 17 comprising a magnetically operated shut - off valve 18 and a by - pass 19a provided with a reduction valve 19 is positioned in the vacuum line leading to a pulsator 16. A magnet 11 in a float 10 of a milk collector 9 operates an electric relay 20 to close the shut-off valve 18 when the milk flow is lower than the predetermined value. A similar valve arratigement may be inserted in the milk conveying side of the milking machine, in the hose 13, so as to reduce the vacuum applied to the interior of the teat cup liners when the milk flow is below the predetermined value, but the degree of vacuum is arranged to be higher than that applied to the pulsation chambers.
