<p>#CMT# #/CMT# The injector (10) has a valve piece (20) fastened to an injector body (12), and a valve sleeve (42) guided in the valve piece. A magnetic actuator (38) is attached at an end (36) of the sleeve, and a valve seat (24) is limited at another end of the sleeve, where the sleeve is directly actuated by the magnetic actuator. The end (36) of the sleeve is formed as an armature plate. The valve piece is engaged at the injector body by an adjusting disk (40) and has a transverse borehole (26), which is connected with a supply borehole (28) in the valve piece above the valve seat. #CMT#USE : #/CMT# Fuel injector for injecting fuel into a self-igniting internal combustion engine. #CMT#ADVANTAGE : #/CMT# The direct actuation of the valve sleeve by the magnetic actuator reduces force necessary for opening a needle-shaped injection valve of the fuel injector and prevents re-feeding of the fuel to the fuel injection system, thus providing simple and cost-effective structure for a high pressure storage system, and reducing pump capacities concerning to high pressure fuel conveying assembly of the high pressure storage system. The fuel injector eliminates the need for a control valve, pressure rod and leakage pipelines, thus reducing installation space of the fuel injector. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a fuel injector with a directly actuated valve sleeve. 10 : Fuel injector 12 : Injector body 20 : Valve piece 24 : Valve seat 26 : Transverse borehole 28 : Supply borehole 36 : End 38 : Magnetic actuator 40 : Adjusting disk 42 : Valve sleeve.</p> |
