Abstract

A fuel injection nozzle has valve member 16 biased to the closed position by a spring 32 and piston 25 housed in bore 24, the space 19 being connected to the inlet 11 of the nozzle by way of a non-return valve at the top of piston 25. A space between the piston and valve member is vented to a drain 27a. In order to minimise leakage of fuel, the piston 25 and the bore 24 define a groove 27 which is connected to the fuel inlet so that any fuel leaking from the end of the piston subjected to the pressure of fuel at the inlet collects in the groove and returns to the inlet via cannelure 30 when the pressure of fuel at the inlet falls. <IMAGE>
