Abstract (en)
[origin: EP1273790A2] The valve has a housing and a piston (30), which engages on a valve needle (10) via a pressure piece (32). The cylindrical pressure piece is guided stationary in a guide sleeve (36) in the housing. It has a dead-end bore (39), open towards the valve piston, with the piston engaging on the base of the bore. A non-central leakage oil bore (37) extending in longitudinal direction of the pressure piece, connects the end face facing the valve needle, to the dead-end bore.
