Abstract
A filter for a fuel injection system includes a body that defines a longitudinal axis, a first end face, a second end, an outer surface extending between the first end face and the second end, an inner surface defining an inner chamber closed at the first end face and open at the second end. The body also defines at least one perforated portion formed in the outer surface extending from the outer surface to the inner surface, at least one slot extending axially along the outer surface. The slot is open and is in fluid communication with the first end face and defines an edge along the outer surface. The edge provides fluid communication between the slot and the perforated portion. Additionally, the edge and an inlet channel of the fuel injection system are adapted to define a first filtration zone. The perforated portion defines a second filtration zone.
