ABSTRACT:
A self-washing device for separating and filtering solid particles from a ow of liquid includes a tubular casing defining an internal chamber, a tangential liquid inlet opening into the internal chamber and arranged to create a vortex in the internal chamber which acts to centrifuge out solid particles and carry them at the vortex periphery, a tangential liquid outlet for discharge of liquid carrying the solid particles from the internal chamber, and a tubular filter disposed longitudinally within the internal chamber for taking and filtering a portion of liquid flow at a center of the vortex, the filter having a longitudinal central duct communicating with at least one longitudinal liquid outlet for the filtered liquid. The device is of particular use in a fuel injection circuit.
