Abstract

L'invention concerne un nettoyeur haute pression (10) comportant un cadre tubulaire (12) servant de structure porteuse, et une unité pompe-moteur (36) présentant un moteur (37) et un groupe de pompe (38) pouvant être entraîné par le moteur, le groupe de pompe (38) étant disposé en amont du moteur (37) dans le sens longitudinal (19) du nettoyeur haute pression (10), et un dispositif de refroidissement de moteur (39) présentant au moins un orifice d'entrée (40) pour de l'air de refroidissement de moteur étant disposé sur le moteur (37) sur le côté opposé au groupe de pompe (38). L'invention vise à améliorer un tel nettoyeur haute pression (10) de telle manière que celui-ci permet un fonctionnement plus fiable. A cet effet, le nettoyeur haute pression (10) comporte une paroi de protection (54) fixée au cadre tubulaire (12) derrière le dispositif de refroidissement de moteur (39) dans le sens longitudinal du nettoyeur haute pression, la paroi de protection recouvrant le au moins un orifice d'admission (40) perpendiculairement au sens longitudinal (19).
