Abstract

In un dispositivo di lavaggio per vetri di copertura di fanali di autoveicoli, comprendente un serbatoio dell'acqua di lavaggio, almeno un ugello spruzzatore (13), associato ad un vetro di copertura, e un generatore di pressione, disposto fra serbatoio dell'acqua di lavaggio e ugello spruzzatore (13), per produrre una pressione di spruzzatura, per migliorare l'effetto di pulitura senza mezzi tergitori meccanici ed evitando un elevato consumo di acqua di lavaggio, il generatore di pressione è eseguito come dispositivo pulsatore (12), che nel funzionamento ad intervalli genera lunghi impulsi di acqua per la spruzzatura tramite l'ugello spruzzatore (13). In un esempio di realizzazione preferito il dispositivo pulsatore (12) presenta una pompa (20) a pistone alternativo, il cui pistone (21) per la corsa di aspirazione è azionato a motore e per la corsa di mandata è azionato da una molla di richiamo (22) caricata durante la corsa di aspirazione (figura 2).
