<p>A jetter apparatus for washing the vacuum-operated teat cup assemblies of a milking machine includes a housing which supports four teat cup attachment assemblies and which defines an internal chamber therein, the housing also defining an inlet to the chamber, and a valve device which is adjustably connected to the housing so as to control the flow of washing liquid entering the chamber through the inlet. The valve device can include a valve stem which is threadingly engaged with the housing, a first end of the valve stem extending into the chamber and the second end extending outside the housing, the first end supporting a conical valve head which, upon rotation of the valve stem, with move toward and away from the inlet and thus control the flow of washing liquid which can flow into the chamber and ultimately through the teat cup attachment assemblies and into the teat cup assemblies attached thereto.</p> |
