Date Mar. 4, 1993.A fuel injector is actuated by cylinder compression pressure acting against the exposed face (31) of piston means (30, 35) to compress fuel in high pressure chamber (45) in injector body (10). The piston means (30, 35) moves against spring (36) and controllable fuel pressure in low pressure chamber (37). The high pressure chamber (45) communicates with injection orifice (68) via delivery chamber (65) and non-return delivery valve (56). Fuel delivery is regulated by varying fuel pressure in low pressure chamber (37) and various means are disclosed for controlling this pressure. |
