<p>The milker has a lower base with a concave bottom and a lower exit under vacuum that can be closed by a float with valve until the milk level pivots and/or raises the float to open the exit. An enclosure body is fitted on the base and includes a main vacuum inlet and a milk inlet nipple positioned and angled to direct milk inflow at the side and/or below the float. An enclosure cap is releasably fitted on the top of the enclosure body and mounts an air valve, pulsation nipples and a further vacuum inlet. A central stem from the bottom extends up through a central passageway in the float and also through the cap to afford a fulcrum or support for an arm that pivots or slides to close the main vacuum inlet when the air valve is opened. The float can pivot and rise to a limited extent when milking or when the milker is inverted for washing.</p> |
