Brenn- oder Treibstoffdüse mit einem kraftausgeglichenen Rückschlagelement

摘要

The axial forces due to fuel pressure acting in opposite directions on the valve member 90 are balanced by providing passages 106, 108 in the member or passages in the injector body 62. Space for fuel leakage is provided between the tip portion 96 of the member 90 and the tip wall 72 of the body 62. The member 90 is actuated for injection through the orifice 80 by solenoids 112, 114 or mechanically or hydraulically. <IMAGE>
