Abstract: An additive atomizing device and further means and a method for the atomization of a liquid additive in a gaseous pressure medium, more particularly compressed air, flowing through a pressure medium flow duct (10). The additive is conveyed from one inlet (26) of an additive passage duct (24) for supplying the additive from an additive supply means (27 and 28) to an outlet (25) opening into the pressure medium flow duct (10). A detecting means (17 and 18) detects at least one physical characteristic in the pressure medium flow duct (10) and signalizes same by way of a signalizing means (19 and 20) to a control means (21). The control means (21) controls a pressure producing device (43 and 47) in a manner dependent on the at least one physical characteristic found by the detecting means (17 and 18) by way of a control connection (23.

Abstract: A plug connector may include an electrically insulated contact holder and a plug contact or contact element located in a contact chamber of the contact holder. The plug connector may be configured as a multi-pole plug connector exhibiting a plurality of contact chambers and contact elements. A plug contact or contact element may have an outwardly curving annular bead and may be configured as a bearing support with an annular groove in the contact chamber. The annular groove may be configured to complement the contour of the annular bead. The annular groove may be located in the terminal area on the connection side of a contact chamber. Alternatively, the annular groove may be located in the contact element and the annular bead may be disposed in the contact chamber. The plug connector may be manufactured without a water tight connection, if desired.
