Abstract

At one of its ends, an injector needle (IN) (6) has a seating area in a nozzle/jet unit (7) and, at its other end, supports a bush (1) that sits on the IN's periphery and slides in relation to the IN. With springy support on the IN, the bush defines a control chamber (10) against a fuel injector's component linking on-axis to the nozzle/jet unit.
