ABSTRACT:
The invention is directed to a self-cleaning liquid filter of the type which includes a filter element through which a liquid sample is selectively passed which is taken from a stream of liquid which flows past one side of the filter element. The filter includes a housing with an inlet, a bypass outlet and a filter outlet. A filter element is mounted in the housing between the inlet and filter outlet and the inlet and bypass outlet communicate with each other through a chamber on the inlet side of the screen, the chamber extending around the inlet. The inlet is positioned in close proximity and oriented relative to the filter element so that liquid entering the housing through the inlet will hit the filter element at a right angle so that when the flow of liquid through the filter outlet is blocked all of the liquid will reflect off of the filter element and outwardly into the chamber for washing off particles on the inlet side of the filter element.
