Abstract

Le dispositif comprend un moteur pneumatique 10 d'essuie-glace à mouvement alternatif et une pompe comportant un piston central 15 ayant deux prolongements 16, 17 formant un second piston, des conduits 13, 14 raccordant les chambres 21, 22 situées de part et d'autre du second piston à deux points 11, 12 du moteur dont les pressions varient cycliquement au cours du cycle de fonctionnement du moteur. Des conduits d'alimentation et de refoulement 31, 29, munis de clapets anti-retour 26, 27, 28 et 30, sont raccordés aux chambres 23, 24 situées de part et d'autre du piston central pour permettre l'aspiration et le refoulement du liquide de lavage par la pompe.
