ABSTRACT:
A self cleaning screen particularly for an engine cooling system comprises a housing having a screen front wall and a rear wall in which there is provided a circular opening. The housing is divided by divider plates connecting between the front and rear walls and extending outwardly from the circular opening to outer side edges of the housing. A baffle is mounted at the center of the opening and is rotatable by a fin or an electric motor. The baffle includes a triangular front plate for closing off a part of the screen aligned with the opening together with a side plate portion which closes off the area defined between the divider plates. As the baffle rotates therefore a portion of the screen extending radially from the centre of the opening to the side edge is closed off so that air does not flow through that area allowing filter debris to fall from the screen.
