DUSTPROOF DEVICE FOR VENTILATING COOLING DEVICE FOR LIQUID COOLING RADIATOR FOR ENGINE

摘要

PURPOSE:To automatically remove the dusts attached onto a ventilating dustproof fitting by installing a dust removing operation device which is temporarily selection- driven from a dustproof operation state to an attached dust removing work state, at least before the completion of the stop of an engine. CONSTITUTION:The title dust removing operating device 16 sets a dust removing port cover 15 into closed posture, and can be serection-operated between the dustproof operation state for setting a ventilating dustproof fitting 3 into dustproof posture and an adsorbed dust removing operation state for setting the dust removing port cover 15 into opened posture and setting a ventilating dustproof fitting 3 into attached dust removing posture. Accompanied with the stop operation of an engine E and operation, at least temporary selective drive from the dustproof operation state to the attached dust removing work state is performed before the completion of stop of the engine E by the instruction of a dustproof instruction device 17. Therefore, the dusts attached onto the ventilating dustproof fitting 3 can be splashed outside from a dust removing port 14 by the cooling wind generated by a cooling fan 2. Therefore, the trouble of deterioration of the cooling faculty of a radiator 5 due to the adhesion of dusts can be prevented.
