<p>A fuel injection nozzle of the inwardly opening type has a valve member (21) which is movable against the action of a spring (24) by fuel under pressure to allow fuel flow through an outlet (20). The valve member is coupled to a piston (29) which is slidable within a cylinder (28) formed in a part (27). The cylinder forms a damping chamber (33) from which there is a leakage path and the part (27) is axially adjustable to determine the degree of restriction.</p> |
