Abstract
An anti-reflection device for preventing the reflection of pressure waves inside a fuel injection valve. The anti-reflection device includes an essentially cylindrical base body with a first base side, a second base side, and an outer surface. The anti-reflection device also includes a longitudinal axis orientated parallel to a propagation direction of a pressure wave. The longitudinal axis penetrating the first base side and the second base side. The anti-reflection device also includes a flow path for fuel formed between the first base side and the second base side. The flow path forming a curve around the longitudinal axis.
