Abstract: A connection device for at least one plug-in portion including an annular external groove includes a housing, into which at least one plug-in portion can be plugged, and also at least in each case one integral locking element and a securing device. A locking element includes a securing portion and a locking portion which can be preassembled in the housing. In the preassembled state, the locking portion, by elastic deflection, permits a plug-in portion to be plugged into the housing and brings about the locking of the plug-in portion in the housing. By means of the securing device, the securing portion can be secured on an outer side of the housing opening against displacement in a circumferential direction. A securing device is designed as a ring which engages around the housing and is movable on the housing at least axially counter to a resistance and has an axial recess in a plugging-in direction.

Abstract: A method of identifying a spray tip from a plurality of spray tips based on a selected fluid is presented. The method comprises the step of selecting the fluid. The fluid is characterized by a set of given physical parameters. The method also comprises the step of selecting an application pressure. The application pressure is sufficient to cause atomization of the fluid through the spray tip. The method also comprises the step of selecting the spray tip for the fluid applicator, based on characteristics of the fluid. The spray tip is selected based on an ability to process the fluid. The spray tip is selected such that the fluid has a viscosity on the order of 10 mPa·s in the shear rate range of 104-106 s?1 to ensure a turbulent flow downstream of a pre-orifice.
