Title: IC engine fuel injection nozzle - has valve needle with piston shaped end which is mounted in pressure relieved hole to prevent pressure fluctuations
Inventor: KOPSE ODON
IPC: F02M55/00
Filed: 1977-06-10
Abstract: The fuel injector (1) is mounted in a holder (2). The holder has a valve seal (3) against which the conical section (4) of the valve needle (5) sits.
