<p>The control armature comprises a low-pressure side suitable for connection on a vacuum pump and a high-pressure side suitable for connection on a supply container for pressure medium. Whereby the connecting conduit on the low-pressure side between the shut-off valve of the intake connecting piece and the shut-off valve of the pump connecting piece as well as the connecting conduit on the high-pressure side between the shut-off valve of the pressure-media-inlet connecting piece and the shut-off valve of the pressure-media-outlet connecting piece are in flow connection by way of a common conduit section in the armature casing, formed in each case by a junction curve for the respective connecting conduit, whereby the conduit section, formed by the junction curves, is at least partially in visual range of the sight glass. These measures permit precise observation of the process of flow on the low-pressure side as well as on the high-pressure side by means of a single sight glass. Furthermore, the flow connection between the low-pressure side and the high-pressure side permits the realization of, for example, the vacuum cleaning of the complete armature.</p> |
