Abstract

The fuel injector (19) comprises a reed valve (35) . The reed valve has at least one orifice and at least one reed valve blade, the or each reed valve blade having a valve head attached to at least one resilient spring arm. The or each valve head opens and closes a respective orifice in the valve seat. A support surrounds the reed valve blade(s). Each spring arm extends inwardly from the support and is curved.
