Ventilator with reversible system for cooling and cleaning radiators

Abstract

A ventilator with a reversible system for cooling and cleaning radiators can reverse the blades ( 1 ) about the shaft ( 5 ) thereof, such that forced air circulation cleans out dust, weed chaff, cereal chaff, sugarcane chaff and other small dirt particles suspended in the air and that end up on or attached to the radiator wings and air inlet grids, thus preventing the entire engine cooling system from heating up.

What is claimed is: 
     
         1 . Ventilator with reversible system for cooling and cleaning radiators which can reverse the blades ( 1 ) around their own shaft ( 5 ), comprising: a set of blades ( 1 ), each one of them having a toothed shaft ( 5 ) that extends into the blades and can be properly rotated to the position of ventilation or exhaustion due to the rack piston ( 15 ) into which the teeth of the shaft ( 5 ) of said piston ( 15 ) fit; said rotation also being achieved through two large bearings ( 4 ) which are arranged in the cylindrical part of the shaft ( 5 ) and contain a gasket holder ( 6 ) and a gasket ( 7 ), containing an o-ring ( 2 ) and a sealing ring ( 3 ) above the upper bearing, and an elastic ring ( 8 ) and a smaller bearing ( 9 ) below the lower bearing; the ventilator comprising an inner cover ( 10 ) and an outer cover ( 19 ) properly joined by a set of screws ( 25 ) that fasten the covers one to another, thus keeping closed a set of guide pins ( 11 ) arranged in a circular fashion, each of said pins containing a compression spring ( 12 ); said ventilator being able to receive compressed air through a n air duct ( 14 ) and an air pin ( 24 ), said pin containing bearings ( 21 ), an elastic ring ( 20 - 23 ) and a retainer ( 22 ) wherein said air duct ( 14 ) is properly fastened to the connecting ring ( 13 ) and protected by a protection cover ( 26 ), also containing an o-ring ( 16 ) that attaches the piston ( 15 ) to the outer cover ( 19 ), and an elastic ring ( 17 ) and a retainer ( 18 ).
