Abstract
A fuel injection nozzle includes a fuel pressure actuated valve member which is biased into contact with a seating by resilient means. The nozzle also includes a spill valve member having a head which is biased into contact with a seating by the resilient means. The head of the spill valve is lifted from the seating by the application of fuel under pressure to a piston portion of the spill valve member. When the head of the spill valve is lifted from the seating fuel is spilled from the nozzle inlet to a drain.
