Descrizione
This is the pulsator from an Alfa-Laval Company Ltd. bucket type milking machine. A milking machine works by creating a vacuum that alternates with the air pressure to draw the milk from the cow’s teats. The pulsator is a device which regulates the alternating vacuum and air pressure cycle to draw milk with damaging the teat. The Alfa-Laval pulsator is made of Bakelite and brass and has only two moving parts which work without oil. This, along with other parts from the Alfa-Laval bucket milker, belonged to the donor’s father-in-law, a part time farmer in Buxton, Derbyshire, 1950–1990.
