Abstract (en)

[origin: EP0391366A2] 1. Fuel injection device for diesel internal combustion engines with a minimum of one pump plunger 4, which is carried and forms a seal in a plunger sleeve 5 and together with the plunger sleeve 5 forms a high-pressure chamber 11, which during the downward movements of the plunger caused by fuel is connected by a control element to a low-pressure chamber 13, the high-pressure chamber 11 being flow- connected to an injection valve 49 via an injection line 48. <??>2.1 The object of the invention is to design the clearance of the fuel injection device as small as possible in order thereby to achieve high injection pressures. <??>2.2 This object is met according to the invention by a permanently open flow connection between the high-pressure chamber 11 and the injection valve 49. <IMAGE>
