Abstract: In an oil-flow regulator for vacuum pumps in milking systems, the amount of oil to be introduced is determined by the dimensions of an annular gap between a valve cone and a restrictor. The valve cone is attached to a diaphragm between the oil chamber and a partial-vacuum chamber that communicates with the suction line to the vacuum pump. When the vacuum pump is turned on, a partial vacuum builds up in the partial-vacuum chamber, forcing the diaphragm and the valve cone upward until the valve cone impacts against an axially adjustable stop. This establishes the oil flow. When the pump is turned off, the partial vacuum in the partial-vacuum chamber cancels out again, the valve cone blocks off the restrictor, an oil flow is interrupted. No oil can flow into the catch chamber when the pump is turned off and lead to an excessive rate of flow and excess oil consumption.
