Portion.The longitudinal axis of nozzle body relative to housing longitudinal axis.By being tangentially entered the liquid of housing, nozzle body is pressed onto
In the depressed part of basin shape, the depressed part is constructed for the supporting member of nozzle body, while nozzle body is placed around into housing
In the rotation of longitudinal axis.This cause effusion liquid beam equally show desired circus movement, so as to a beam nozzle phase
Under same pressure, it can be loaded to bigger surface with liquid.
However, if nozzle body has around the very high rotating speed of the longitudinal axis of housing, then this can cause to escape from outlet
The liquid beam fan out gone out, and thus, reduce the cleaning effect of liquid beam of the appearance to surface to be cleaned.
In addition to it is around the surround movement of the longitudinal axis of housing, nozzle body is also implemented around the longitudinal axis of its own
Spinning.The spinning also results in the fan out of the liquid beam from outlet effusion, and and then causes to reduce cleaning effect.
For the rotating speed of limits nozzle body, proposed in the A1 of DE 44 19 404, a kind of imbedding piece is inserted into housing
