Abstract (en)
[origin: EP0730090A2] The valve has a valve member (5) moving axially in a boring (3) in a valve body (1). The conical valve seal surface (7) meets a conical valve seat surface (9) on the boring connecting to a dead-end cavity (21) on the combustion chamber side. There is a pressure space (15) between the valve member and the boring wall. The injection channel (23) is downstream of the valve seat in the inner wall of the injection valve. The intake zones of the injection channel are rounded. The upper intake zone has a rounding (RA) of greater radius and the lower zone has a rounding of smaller radius. The greater radius is 0.75-1.5 times the dia. (D) of the injection channel, and the lesser one is 0.2-1.0 of the same.
