Abstract

In the case of a fluidic nozzle (12) a nozzle body (13) is fixed in a housing (17) by a form-locking latching connection (18). For this purpose, an elastically deformable latching body (14) engages in a recess (16) of the housing (17). The operational position of the nozzle body (13) is thereby defined with high accuracy, with the result that an undesirable escape of the liquid between the nozzle body (13) and the housing (17) is prevented. Furthermore, at the same time the contact surface can be reduced here to a section (20) which is inclined toward an outlet opening (19) of the fluidic nozzle (12) and has a correspondingly improved sealing.
