摘要

The system has a spray nozzle (1) that corresponds to an outlet orifice (14) of a valve stem (12) and is intended to apply washing liquid. The nozzle and the orifice are displaced with respect to each other during a driving movement of a windshield wiper shaft (2) so as to alternatively open and close the orifice. The stem is integrated on a small brass tube (7), and the nozzle is disposed in a nozzle body (15).
