Patent ID: 6923388

Claim:
A fuel injection valve for internal combustion engines, comprising a valve body ( 1 ), in which a pistonlike valve member ( 5 ) is longitudinally displaceably disposed in a bore ( 3 ), the valve member ( 5 ) being surrounded, over at least part of its length, by a pressure chamber ( 7 ) that can be filled with fuel, and a valve seat ( 18 ), embodied on the end toward the combustion chamber of the bore ( 3 ), on which seat the valve member ( 5 ) comes to rest with a valve sealing face ( 26 ) in a closing position, so that the pressure chamber ( 7 ) is disconnected from at least one injection opening ( 20 ) located downstream of the valve sealing face ( 18 ), and first and second parallel annular grooves ( 30 , 32 ) disposed axially toward the valve seat ( 18 ) and embodied in the end region of the valve member ( 5 ) toward the combustion chamber, the valve sealing face ( 26 ) being disposed on an annular land ( 27 ) that remains between these two annular grooves ( 30 ; 32 ), wherein the annular land ( 27 ) of the valve member ( 5 ) that remains between the annular grooves ( 30 ; 32 ) is resilient in the direction of motion of the valve member ( 5 ).
